MS-1917

As a junior doctor on the infectious diseases ward, you come across a 42-year-old man who has been experiencing shortness of breath, haemoptysis, weight loss, and cough for the past two months. He has lost 5kg in weight and has recently returned from India where he worked for 18 months. Blood tests show no abnormalities, but a chest x-ray reveals left upper zone consolidation surrounding a round, mass lesion. Further evaluation through high-resolution CT (HRCT) of the chest shows left upper lobe consolidation surrounding a 1.7cm, smooth rimmed lesion with a degree of calcification, with no evidence of cavitation or other acute lung pathology. The diagnosis is primary tuberculosis with evidence of tuberculoma formation. Which cytokine is integral to the development of this man’s CT findings?
