Pediatric Moyamoya Syndrome Secondary to Tuberculous Meningitis: A Case Report.

ABSTRACT

Objectives: Tuberculosis is uncommon in the United States and a rare cause of meningitis in children with severe neurologic consequences. Tuberculous meningitis (TBM) is an even rarer cause of moyamoya syndrome with only a handful of cases previously reported. Methods: We report the case of a female patient who initially presented at 6 years of age with TBM and developed moyamoya syndrome requiring revascularization surgery. Results: She was found to have basilar meningeal enhancement and right basal ganglia infarcts. She was treated with 12 months of antituberculosis therapy and 12 months of enoxaparin and maintained on daily aspirin indefinitely. However, she developed recurrent headaches and transient ischemic attacks and was found to have progressive bilateral moyamoya arteriopathy. At age 11 years, she underwent bilateral pial synangiosis for the treatment of her moyamoya syndrome. Discussion: Moyamoya syndrome is a rare but serious sequalae of TBM and may be more common in pediatric patients. The risk of stroke may be mitigated by pial synangiosis or other revascularization surgeries in carefully selected patients.
