Primary diffuse leptomeningeal primitive neuroectodermal tumor is a rare meningeal neoplasm which can masquerade as chronic meningitis. While the clinical presentation and radiological features may provide a clue to this condition, meningeal biopsy is essential to clinch the diagnosis. A high index of suspicion and a low threshold for re-evaluating cases of neuroinfection that do not respond to empirical therapy are essential in this scenario. We present the case of a nine year old boy who was initiated on antituberculous treatment for chronic meningitis with hydrocephalus. Meningeal biopsy revealed a primary diffuse leptomeningeal primitive neuroectodermal tumor.
