A 25-year-old man was admitted with fever, headache, vomiting and vision loss for 2 months. Clinical examination revealed neck stiffness, inability to perceive projection of light and papilledema. Magnetic resonance imaging (MRI) of brain showed nodular thickening of basal meninges with contrast enhancement and multiple ring-enhancing lesions [Figure 1] and [Figure 2]. Cerebrospinal fluid was suggestive of tubercular meningitis with positive polymerase chain reaction for tuberculosis (TB-PCR).{Figure 1}{Figure 2}

Tuberculous meningitis predominantly affects basal regions of brain, causing accumulation of exudates in suprasellar, Sylvian and interpeduncular cisterns, manifesting as optochiasmatic arachnoiditis (OCA). [1] It usually occurs in young individuals and causes slowly progressive vision loss. [2]
