title: [A rare case of middle fossa neuroepithelial cyst accompanied by chronic subdural hematoma].
abstract: We reported a rare case of middle fossa neuroepithelial cyst accompanied by chronic subdural hematoma. An eight-year-old boy was admitted to our hospital due to headache, disturbed consciousness and right hemiparesis. CT disclosed a left marginal high density in the left subdural space and remarkable midline shift. MRI showed a hematoma in the left to temporal tip extending to the chronic subdural hematoma. Radiological examinations revealed a cystic lesion with chronic subdural hematoma. An operation was performed to remove the hematoma. Intraoperatively, the hematoma in the cyst and the chronic subdural hematoma were observed. Histopathological diagnosis of the cyst wall was neuroepithelial cyst. The relationship between the neuroepithelial cyst and chronic subdural hematoma was discussed.
