A mucopyocele of the clivus: case report.
OBJECTIVE
There are increasing reports of nasal sinus mucopyoceles eroding the base of the cranium and causing the rapid onset of neurological complications. Uncommon presentations can mimic tumors, but the infectious nature mandates an urgent surgical decompression. It is important to document these uncommon presentations. CLINICIAL PRESENTATION: A mucopyocele of the clivus is reported in a patient with a frequent history of sinusitis. Diplopia caused by an acute sixth nerve palsy prompted the radiological diagnosis with computed tomography and magnetic resonance imaging.


METHODS
Transsphenoidal drainage of the lesion lead to marked improvement in the patient.


CONCLUSIONS
This is the third reported case of a clival mucocele. Mucoceles of nasal sinuses can erode intracranially, causing neurological sequalae, and clival involvement is extremely rare. Early drainage leads to marked improvement.
