[Multicystic sphenoethmoidal mucocele with intracranial extension presented with generalized convulsion: a case report].
A 53-year-old male presented with generalized convulsion. Magnetic resonance imaging and computed tomography revealed large sphenoethmoidal mucocele extending intracranially. Signal intensities between paranasal and intracranial portion of the mucocele were different. Preoperatively it was not obvious that intracranial portion of the mucocele communicated with paranasal portion of the mucocele. We approached the paranasal portion of the mucocele by transsphenoidal approach resulting in disappearance of the intracranial portion of the mucocele. Sphenoethmoidal mucocele with intracranial extension presenting with generalized convulsion was the first case in the literature. Transsphenoidal approach for sphenoethmoidal mucocele with intracranial extension is the first choice of surgical treatment, though neuroimaging shows that there is no communication between paranasal and intracranial portion of mucocele.
