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.
Insights
A rare case of a neuroepithelial cyst in a child was found with a chronic subdural hematoma. Surgical removal of the hematoma was successful, highlighting the cyst-hematoma association.
Area of Science:
- Neurology
- Neurosurgery
- Pediatric Neurology
Background:
- Neuroepithelial cysts are rare congenital brain malformations.
- Chronic subdural hematomas (CSDH) are collections of blood that can occur in children.
Observation:
- An 8-year-old boy presented with headache, altered consciousness, and right hemiparesis.
- CT and MRI revealed a left middle fossa cystic lesion and a significant chronic subdural hematoma with midline shift.
Findings:
- Intraoperative findings confirmed both a cyst and a chronic subdural hematoma.
- Histopathological examination of the cyst wall confirmed it as a neuroepithelial cyst.
Implications:
- This case highlights a rare association between neuroepithelial cysts and chronic subdural hematomas in pediatric patients.
- Understanding this relationship is crucial for accurate diagnosis and effective surgical management.
