Case in brief
A woman in her mid-60s presented with orbital apex syndrome, characterized by dysfunction of multiple cranial nerves. Diagnostic challenges arose due to the rarity of tuberculosis-related OAS in non-endemic regions. A dural biopsy confirmed tuberculosis meningitis with necrotising granulomas and acid-fast bacilli. Following 2 months of modified anti-tuberculosis therapy, she showed improvement in extraocular motility and visual acuity.
Diagnostic / clinical pearl
Clinicians should consider tuberculosis as a potential cause of orbital apex syndrome, especially in atypical presentations in non-endemic areas.
