Abstract: | Intracranial neurenteric cysts are rare entities. The term is currently used to describe epithelial cysts that are lined with a presumed endodermal-derived epithelium and are mostly located in the posterior fossa.Preoperative diagnosis is often difficult because of their clinical presentation, which may resemble a subarachnoid hemorrhage, and the radiological aspect, which can mimic vascular pathologies.We describe a posterior fossa neurenteric cyst in a 27-year-old woman, who presented with sudden headache as the only symptom and who was addressed to our hospital for subarachnoid hemorrhage. Diagnostic angiography was negative and MRI revealed a prepontine cystic lesion. The patient underwent a posterolateral approach on the right side, with subtotal resection of the lesion.We discuss the embryologic, diagnostic and therapeutic aspects of these cysts and review the literature. |
