Abstract

Neuroenteric cysts, are rare benign endodermal lesions which mostly occur in the central nervous system. We report a case of a neuroenteric cyst in a 30-year-old man who presented with rhinoliquorrhea at the ENT department. After clinical examination, a semisolid mass was revealed in the left nostril. The Computer Tomography Scan revealed a frontal ethmoidal nasal meningoencephalocele with inferior extension into the left nostril. Gadolinium-enhanced T1-weighted MR images showed a well-defined frontal mass with ring-like enhancement and extension into the cribriform plate of the ethmoid bone and into the left nostril. The lesion measured 10/10/20 mm. The tumor was totally resected using a unilateral subfrontal approach. At five months’ follow-up, the patient showed significant amelioration of symptoms and remission of cerebrospinal fluid leakage. Native and Contrast-enhanced Cerebral Computer Tomography, as well as Magnetic Resonance Imaging showed total surgical resection of the cyst. Supratentorial neurenteric cysts involving the anterior fossa are rare. Intracranial neurenteric cysts should be differentiated by any well-demarcated cystic tumors. The gold standard treatment remains complete surgical resection with favorable outcome.
