title: Third ventricular neuroepithelial cyst originating from the massa intermedia--case report.
abstract: A 47-year-old female presented with a 3-year history of progressive emotional disturbance. Computed tomography and magnetic resonance imaging revealed a cyst in the third ventricle causing hydrocephalus. Endoscopic surgery found the cyst originated at the massa intermedia. Histological examination confirmed the diagnosis of neuroepithelial cyst. Neuroepithelial cyst originating from the massa intermedia may be due to persistence of neuroepithelial crest at this location.
