Abdominal cyst formation following ventriculoperitoneal shunt in a case of hydrocephalus due to cryptococcal meningitis

A 54-year-old woman was admitted to the hospital for evaluation of meningitis. Tuberculous meningitis was suspected initially because of general findings and a high adenosine deaminase activity (ADA) value in the cerebrospinal fluid. Administration of antituberculous drugs was not effective. Computed tomography scanning revealed progression of ventricular enlargement. A ventriculo-peritoneal shunt was placed upon diagnosis of hydrocephalus due to meningitis. The presence of a large abdominal cyst formation was demonstrated. Cryptococcus was detected in the cyst fluid, leading to a diagnosis of cryptococcal meningitis. Intravenous administration of fluconazole (400 mg/day) was begun. Excision of the cyst was performed when Cryptococcus was no longer detected in the cyst fluid. The patient recovered uneventfully.
