“…Neurenteric cysts are rare congenital lesions mostly found in intraspinal or intracranial locations. 8 – 11 The existence of extradural neurenteric cysts may be explained by communication between intra- and extradural spaces through dysraphic spinal columns. 12 It is proposed that neurenteric cyst embryological formation progresses through complex endodermal and ectodermal interactions, and abnormal inter-layer adhesions may give rise to locations anywhere between the gut and skin, including the temporal bone.…”

Neurenteric cysts are rare, developmental malformations mainly found in the spinal canal. The authors report on a 29-year-old woman who presented with congenital left-sided hearing loss and a 9 days history of left ear pain and facial weakness (House–Brackmann IV). Radiological examination revealed a complex 7 mm cystic structure involving the petrous and mastoid portions of the left temporal bone. Intraoperatively, a red-brown multicystic mass was discovered and excised completely. Histologic findings showed simple columnar epithelium with goblet cells and bilayers of submucosal musculature, resembling normal intestinal linings. Post resection, the patient regained nearly full facial nerve capabilities (House–Brackmann II) with complete resolution of pain, but no changes to her hearing. The objectives of this case report are to describe the clinical, radiologic, intraoperative, and pathologic characteristics of an extradural temporal neurenteric cyst with sensorineural deficits to contribute to the growing knowledge regarding this rare entity.
