A 29-year-old physiotherapist with a history of bilateral vitreous haemorrhage is referred due to progressive ataxia. Which of the following is the most likely diagnosis?
Your Answer:
Correct Answer: Von Hippel-Lindau syndrome
Explanation:Retinal and cerebellar haemangiomas are key features of Von Hippel-Lindau syndrome. Retinal haemangiomas are bilateral in 25% of patients and may lead to vitreous haemorrhage. Von Hippel-Lindau (VHL) syndrome is an autosomal dominant condition predisposing to neoplasia. It is due to an abnormality in the VHL gene located on short arm of chromosome 3.

A 66 year-old marketing analyst presents to the respiratory clinic with a 2-month history of progressive weakness and shortness of breath. He finds it difficult to stand from sitting, and struggles climbing stairs. He is an ex-smoker with chronic obstructive pulmonary disease (COPD). He had a recent exacerbation one month ago for which he was treated by the GP with a course of oral prednisolone, during which time his weakness transiently improved. On examination, you note a left-sided monophonic wheeze and reduced breath sounds at the left lung base. Blood tests and a chest x-ray are requested. Hb 145 g/L WCC10.5 109/L, Na+136 mmol/L, K+ 4.3 mmol/L, Urea 6.8 mmol/L, Creatinine 93 mmol/L, Calcium 2.62 mmol/L, Phosphate 1.44 mmol/L, Chest x-ray shows hyperinflated lungs, left lower lobe collapse and a bulky left hilum What is the most likely cause of this patient's weakness?
Your Answer:
Correct Answer: Lambert-Eaton myasthenic syndrome
Explanation:This man has a small-cell lung cancer (SCLC) and associated Lambert-Eaton myasthenic syndrome – a well-recognized paraneoplastic manifestation of SCLC. This classically affects the proximal muscles, especially in the legs, causing difficulty in standing from a seated position and climbing stairs. In contrast to myasthenia gravis, eye involvement is uncommon. Treatment with steroids is often helpful, which explains his transient symptomatic improvement during treatment for his COPD exacerbation. Steroid myopathy does not fit as the symptoms started well before his course of prednisolone. Although the patient is mildly hypercalcaemic, this would not be sufficient to produce his presenting symptoms, although it does reinforce the suspicion of lung malignancy. Motor neurone disease would be unlikely in this context and would not improve with steroids. Myasthenia gravis could produce these symptoms, but in the context of a new lung mass is a less viable diagnosis.

A 53-year-old cashier with a history of chronic back pain presents for a check-up. He is aware of a dragging feeling affecting his left foot when he tries to walk. This has developed since a minor injury to his left knee. On examination, he has weakness of dorsiflexion and eversion of the left foot. The right is unaffected and plantar flexion and inversion are normal on the left. MRI of the spinal cord shows degenerative disc changes at multiple levels, but no evidence of cord or nerve root impingement. Nerve conduction studies and EMG results are pending. Which of the following sensory loss patterns would you expect to find in association with this motor defect?
Your Answer:
Correct Answer: Sensory loss over the dorsum of the foot and anterolateral leg
Explanation:This patient presentation is unlikely to be an L5 nerve root lesion given the results of the MRI scan. Therefore, the most likely diagnosis is a mononeuritis affecting the left common peroneal nerve. This would lead to sensory loss over the dorsum of the foot and anterolateral leg on the left.

A 21-year-old patient is referred to the tertiary neurology clinic because of a possible diagnosis of Juvenile Parkinson’s disease. His symptoms began predominantly with dystonia affecting the lower limbs, but he now has more classical signs of older onset Parkinson’s including tremor, bradykinesia, and rigidity. You map out his family tree and understand that his sister developed Parkinson’s at the age of 16 but that his parents do not have signs of Parkinson’s. Which of the following is the most likely mode of inheritance?
Your Answer:
Correct Answer: Autosomal recessive
Explanation:Juvenile Onset Parkinson’s is an autosomal recessive condition that usually presents in late childhood to early adulthood, initially with gait disorders caused by lower limb dystonia that later develops to the more classical signs Parkinson’s.

A 22-year-old male has had complex tics since childhood. He repeatedly bends his knees and rubs his nose. He is prone to loud vocalisations, sometimes including swear-words. A diagnosis of Gilles de la Tourette syndrome has been made. Which of the following is the best treatment option?
Your Answer:
Correct Answer: Risperidone
Explanation:Gilles de la Tourette syndrome is the most severe and rare of the tic syndromes, consisting of multiple tics involving both motor actions and vocalisation. Onset is usually in childhood. Symptoms include utterance of obscenities (coprolalia); echolalia (repetition of another person’s spoken words) and palilalia (involuntary repetition of words, phrases, or sentences).
The underlying cause is unknown, with no particular imaging or standard histopathological abnormalities having been identified. The EEG shows non-specific abnormalities in about half of patients. However, more recent immunocytochemical studies have suggested altered dopamine uptake in the striatal system.
Risperidone is an effective therapeutic option without the effects associated with chlorpromazine and haloperidol. -

A 43-year-old police officer is admitted with a history of unsteadiness and slurring of speech. This has worsened over a period of three months. He complains of a tremor affecting his right hand and diplopia on right lateral gaze. He smokes 30 cigarettes a day and takes regular diclofenac for his arthritis. On examination, he is dysarthric and feels nauseated. Fundoscopy is normal, however there is marked horizontal nystagmus and evidence of a right VI nerve palsy. There also appears to be some mild facial weakness on the right side. Upon conducting Weber’s test, a louder tone is heard in the left ear. On conducting the Rinne test, both ears are normal. On examination of the upper limb, there is a right intention tremor and dysdiadochokinesis. Tone, power and reflexes are normal. On examination of the lower limb, tone, power and reflexes are normal, however he appears to walk with a broad-based gait and is leaning to the right. Lumbar puncture: Opening pressure 13 cm H20 (5–18) Protein 0.67 g/l (0.15–0.45) WCC 3 cells/ml (<5) Red cell count (RCC) 2 cells/ml (<5) Glucose 3.2 mmol/l (3.3–4.4) Blood glucose 5.8 mmol/l (3.0–6.0) Oligoclonal bands Present Serum oligoclonal bands Present Magnetic resonance scan shows a calcified lesion broadly attached to the petrous part of the temporal bone. In view of the above history and findings, what is the likely cause of this patient’s symptoms?
Your Answer:
Correct Answer: Meningioma of the cerebellar pontine angle
Explanation:This patient has a combination of right cerebellar dysfunction with right-sided cranial nerve palsies (VI, VII, and VIII). The magnetic resonance imaging (MRI) shows a calcified meningioma within the right cerebellar pontine area, which would account for these findings. The cerebrospinal fluid (CSF) analysis shows oligoclonal bands, however, these are matched in the serum, which reflects a systemic inflammatory response from his rheumatoid arthritis.
The MRI scan and CSF analysis would not be consistent with progressive multiple sclerosis. The progressive nature of her symptoms would be against a diagnosis of brainstem infarct, and one would expect more pyramidal signs in the peripheral nervous system.

A 26-year-old graduate student with a history of migraines presents for examination. His headaches are now occurring about once a week. He describes unilateral, throbbing headaches that may last over 24 hours. Neurological examination is unremarkable. Other than a history of asthma, he is fit and well. What is the most suitable therapy to reduce the frequency of migraine attacks?
Your Answer:
Correct Answer: Topiramate
Explanation:It should be noted that as a general rule 5-HT receptor agonists are used in the acute treatment of migraine whilst 5-HT receptor antagonists are used in prophylaxis. NICE produced guidelines in 2012 on the management of headache, including migraines. Prophylaxis should be given if patients are experiencing 2 or more attacks per month. Modern treatment is effective in about 60% of patients. NICE advises either topiramate or propranolol ‘according to the person’s preference, comorbidities and risk of adverse events’. Propranolol should be used in preference to topiramate in women of child bearing age as it may be teratogenic and it can reduce the effectiveness of hormonal contraceptives.

A 25-year-old athlete presented with a 7-month history of difficulty gripping things. He complained of finding it particularly difficult in cold weather. He remembered his father having similar problems. Upon examination, he had a bilateral ptosis with weakness of the facial muscles. He also had difficulty opening his eyes quickly. Limb examination revealed distal weakness in both hands with difficulty opening and closing both hands quickly. Which of the following is the most likely diagnosis?
Your Answer:
Correct Answer: Myotonic dystrophy
Explanation:Myotonic dystrophy is the most likely diagnosis here.
It is a multisystem disorder causing cognitive impairment, cataracts, cardiac problems and testicular atrophy, as well as affecting the muscles. Patients have muscle weakness, normally worse distally, and/or myotonia (which is worse in cold weather).
On examination, patients may also have frontal balding, a myopathic facies, bilateral ptosis, an ophthalmoplegia and wasting of facial muscles and other limb muscles. Myotonic dystrophy is associated with diabetes mellitus and pituitary dysfunction.
Diagnosis is normally based on clinical features with a characteristic electromyogram (EMG) of myotonic discharges. Creatine kinase is generally normal and muscle biopsy is non-specific. -

During these episodes, she can be unresponsive to questioning and has no recollection of them. Which of these drugs is contraindicated in this condition?
Your Answer:
Correct Answer: Carbamazepine
Explanation:The patient’s history points to absence seizures. Carbamazepine has been shown to aggravate generalized seizure types, especially absence seizures, because it acts directly on the ventrobasal complex of the thalamus which is critical to the neurophysiology of absence seizures.

A 71-year old gentleman presents with a subacute history of intermittent difficulty in walking, dry mouth, and variable slurring of speech. When the latter is severe he also has difficulty in swallowing. He has lost 3 kg in weight in the last 2 months. On examination he has bilateral mild ptosis, dysarthria, and proximal weakness of the upper and lower limbs, and he is areflexic. The degree of weakness is variable. Nerve conduction studies confirm the clinical suspicion of a neuromuscular junction disorder. Which of the following autoantibodies is likely to be the underlying cause of his neurological symptoms?
Your Answer:
Correct Answer: Anti-voltage-gated, calcium-channel antibody
Explanation:The clinical picture points to Lambert– Eaton myasthenic syndrome (LEMS) which often presents with weakness of the arms and legs. In LEMS, antibodies against voltage-gated calcium channels (VGCC) decrease the amount of calcium that can enter the nerve ending, causing autonomic symptoms like dry mouth and slurring of speech, as seen in this patient.

A 20-year-old gentleman presents to the A&E department complaining of a sudden-onset occipital headache associated with vomiting. His symptoms started 2 hours previously and are continuing. He has a previous history of infrequent migraine without aura, which also causes nausea but not vomiting. He rated his current headache as much more severe than his usual migraine. Examination is unremarkable. In particular, there is no neck stiffness or photophobia. Which of the following management options would be the most appropriate?
Your Answer:
Correct Answer: CT brain scan, followed by lumbar puncture if CT normal
Explanation:The patient presented with sudden-onset headache that is more painful than his usual migraine attacks. This gives a high suspicion of subarachnoid haemorrhage; thus, a CT brain scan should be ordered first to rule this out. However, a normal CT scan is apparent in 30% of patients with subarachnoid haemorrhage and should be referred for lumbar puncture to look for red blood cells.

She complains of pain in her right arm when twisting door handles anticlockwise. Phalen’s and Tinel’s tests are negative. She is otherwise neurologically intact. Which of the following is the most likely diagnosis?
Your Answer:
Correct Answer: Pronator teres syndrome
Explanation:Entrapment of the median nerve by pronator teres causes a median nerve neuropathy, which is worse during pronation of the forearm. Examination should involve excluding carpal tunnel syndrome and pronation of the affected forearm against resistance, which brings on the pain. Unlike carpal tunnel syndrome, the median nerve proximal to the wrist may be tender to palpation.

Which of the following features is not associated with an oculomotor nerve palsy?
Your Answer:
Correct Answer: Miosis
Explanation:Oculomotor nerve palsy is an eye condition resulting from damage to the third cranial nerve or a branch thereof. A complete oculomotor nerve palsy will result in a characteristic down and out position in the affected eye. This is because the lateral rectus (innervated by the sixth cranial nerve) and superior oblique (innervated by the fourth cranial or trochlear nerve), is unantagonized by the paralyzed superior rectus, inferior rectus and inferior oblique. The affected individual will also have a ptosis, or drooping of the eyelid, and mydriasis (pupil dilation), not miosis.

A 13-year-old boy complains of several episodes of collapse. He describes the majority of these episodes occurring when he is laughing. He states that he loses power in his legs and falls to the ground. He is alert throughout and recovers quickly. He also describes excessive daytime sleepiness with episodes in the morning of being awake but being unable to move his body. Examination is unremarkable. A diagnosis of narcolepsy is made. Which of the following is the first line treatment for excessive daytime sleepiness?
Your Answer:
Correct Answer: Modafinil
Explanation:Narcolepsy is a rare condition characterised by excessive daytime sleepiness, sleep paralysis, hypnagogic hallucinations, and cataplexy (sudden collapse triggered by emotion such as laughing or crying). There is no cure for narcolepsy. Treatment options include stimulants, such as methylphenidate (Ritalin) or modafinil (Provigil), antidepressants, such as fluoxetine (Prozac), citalopram (Celexa), paroxetine (Paxil), sertraline (Zoloft) and sodium oxybate (Xyrem). Modafinil has replaced methylphenidate and amphetamine as the first-line treatment of excessive daytime sleepiness (EDS).

A 48-year-old hairdresser presented to her GP complaining of tingling in the right palm and right wrist pain. She had intermittently experienced these symptoms; however, recently they had been keeping her awake all night. She had noticed a reduction in grip and was struggling to work at the salon. Otherwise, she felt well in herself and had not noticed any weakness in the other hand or lower limb. Her weight was stable, and she denied any neck problems or swallowing difficulties. She had a past medical history of hypothyroidism and hypertension and took regular thyroxine, Bendroflumethiazide and ibuprofen. She was a non-smoker and rarely drank alcohol. On examination, she appeared alert and orientated. Fundoscopy and cranial nerve examination were all normal and neck movements were full. On examination of the upper limb, there was wasting over the right thenar eminence and fasciculations with a small burn over the right index finger. There was weakness of thumb abduction and opposition, with loss of pinprick and light touch sensation over the thumb, index and middle finger in the right hand. Nerve conduction studies showed absent sensory action potential in right median palmar branches and denervation of the right abductor pollicis brevis. What is the most likely diagnosis?
Your Answer:
Correct Answer: Median nerve palsy
Explanation:The history is consistent with carpal tunnel syndrome (CTS) arising as a result of pressure on the median nerve in the carpal tunnel. The median nerve supplies the muscles of the thenar eminence: the abductor pollicis (C7, C8), flexor pollicis brevis and opponens pollicis, and the lateral two lumbricals. The nerve conduction studies confirm marked denervation and absent sensory potentials within the median nerve territory.

A 32 year-old man presents with his first generalized tonic-clonic seizure (GTCS). He has been complaining of headaches for the past 2 weeks, although he has been able to continue working at his job. Upon examination, he has mild left hemiparesis and bilateral extensor plantar responses. General examination is otherwise unremarkable. An urgent CT scan of the brain shows a 5cm multicentric mass lesion in the right frontal lobe with surrounding vasogenic oedema and some hemisphere shift. Which of the following is the most likely underlying pathology?
Your Answer:
Correct Answer: Glioblastoma
Explanation:Glioblastoma multiforme, also considered as grade IV astrocytoma, is the most malignant form of the tumour and accounts for about 20% of all cerebral tumours. These often remain clinically silent until they have reached a large enough size. In adults, glioblastoma multiforme usually occurs in the cerebral hemispheres, especially the frontal and temporal lobes of the brain. About half occupy more than one hemisphere at presentation, and some are multicentric. Biopsy shows high cellularity with mitoses, pleomorphism, and vascular hyperplasia. Prognosis is extremely poor, with only 20% surviving beyond 1 year and 10% beyond 2 years.

A 53 year-old dancer presents to the ED with increasing weakness. She has no pertinent past medical history aside from a recent diarrhoeal illness, which she attributes to an undercooked chicken meal. Her husband says that she has been unable to get up out of a chair for the past day. Upon examination, there is bilateral limb weakness and areflexia noted, but it is more severe in the lower limbs. You notice that if she lies flat in the bed, her oxygen saturations fall by around 2% on the pulse oximeter and she is unable to perform spirometry. Which of the following represents the most appropriate immediate management of choice in this patient?
Your Answer:
Correct Answer: ITU review for consideration of ventilation
Explanation:This woman has a history that is suggestive of Guillain– Barré syndrome. This may be precipitated by Campylobacter, and her history of recent diarrhoeal illness is pointing towards that. Certain features point to a poor prognosis, including rapidity of onset, reduced vital capacity or respiratory failure, age >40 and reduced amplitude of compound muscle action potential. Her inability to perform spirometry and desaturating whilst lying flat are suggestive of impending respiratory muscle weakness. Review for consideration of ventilation is recommended. Further management of choice for Guillain-Barre syndrome is IV immunoglobulins. Steroids have no value in the treatment of the condition.
