title: Tuberculous meningitis with blindness and perichiasmal involvement on MRI.
abstract: An 11-year-old boy with tuberculous meningitis developed blindness, a rare complication of this disease in the United States. Magnetic resonance imaging demonstrated perichiasmal enhancement, suggesting that arachnoiditis caused the visual loss. Serial neuroimaging over 7 months revealed a persistent inflammatory process in the chiasmatic cistern, hydrocephalus, and progressive cerebral infarctions.
