Abstract
A 33-year-old woman presented with occasional mild nonlateralized headache. Examination was normal. Brain MRI revealed a neuroglial cyst in the right hemisphere which expanded slowly but relentlessly over subsequent years (figure 1; figure e-1 on the Neurology® Web site at www.neurology.org). At the last MRI, the lesion produced considerable mass effect, but the patient’s examination was still normal. She refused surgery. Neuroglial cysts are uncommon congenital lesions.1,2 Unlike the more common arachnoid cysts, they are located within brain parenchyma and arise from remnants of embryonic neural tube elements, sequestered in the developing white matter. Most neuroglial cysts remain stable in size. Minimal but persistent intracystic CSF secretion may explain cyst expansion over time.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
