Transethmoidal meningocele: an unusual complication of intracranial neoplasm.

Cranial meningoceles/encephaloceles are congenital malformations characterised by protrusion of the meninges and/or brain parenchyma because of a skull defect. Meningoceles secondary to an intracranial neoplasm have not been reported in the published literature. We report a unique case of a 42-year-old man who presented with a sudden onset of altered sensorium. Transethmoidal meningocele secondary to an intraventricular epidermoid cyst was detected on imaging.
