Giant frontal mucocele invading the anterior cranial fossa and orbit

Abstract

Mucocele is a rare intracranial pathology. In majority mucoceles arise within the frontal and ethmoid sinuses. Intracranial and intraorbital extensions are uncommon. A 48 year old male with a history of head trauma with multiple craniofacial fructures for 30 years. After 30 years came to first generalized epileptic seizure, also the leftside exophthalmos was observed. The radiological investigations, computed tomography ( CT ) and magnetic resonanse ( MRI ), showed large extracerebral pathological mass invading the left frontal and ethmoid sinuses, left orbit and anterior cranial fossa with left frontal lobe compression. The left side fronto basal craniotomy was performed. The histopathological diagnosis was mucocele. Postoperative neurological examination revealed no deficit. The patient was seizures free and in good condition discharged from the department.Mucocele is a rare, benign pathology arising intracranial from the sinuses. The results are good, the frequency of complication is low.
