MS-3685

A 55-year-old man presents with a 3-month history of a progressive headache that is worse in the morning, nausea and reduced appetite. He reports that he has been bumping into hanging objects more frequently.

During the examination of his cranial nerves, a left superior homonymous quadrantanopia is detected. However, his visual acuity is normal.

Given the ophthalmological finding, where is the suspected location of the space-occupying lesion? An urgent MRI brain has been scheduled.
