Primary diffuse leptomeningeal gliomatosis mimicking meningeal tuberculosis.

Primary diffuse leptomeningeal gliomatosis (PDLG) is a rare condition, with only 45 cases recorded to date, characterized by infiltration of the meninges by glial cells without evidence of primary tumor in the brain or spinal cord parenchyma. Here, we describe a patient with PDLG who was managed with tuberculostatic drugs owing to multiple findings that were suggestive of tuberculous meningitis. A 19-year-old woman presented with headaches and behavioral changes.
