Cavernous hemangioma of the sphenoid sinus: case report and review of the literature.
BACKGROUND
Few cases of paranasal sinus cavernous hemangiomas have been reported in the literature. We report the first case of cavernous hemangioma of the sphenoid sinus and discuss therapeutic considerations and differential diagnosis.


METHODS
A case of sphenoid sinus tumor in a 67-year-old woman is reported. The initial symptoms were a horizontal diplopia, a left facial dysesthesia, and a recent history of unusual headache. Physical examination revealed a left VIth nerve paresis. A CT scan was performed showing a hypodense homogeneous mass in the sphenoid sinus that was not enhanced after administration of contrast medium. MR study demonstrated on T1-weighted image an isointense nonenhancing homogeneous mass filling the sphenoid sinus. On T2-weighted images the tumor mass displayed a mild hyperintense signal. The patient was operated on via a transsphenoidal approach with total removal of the tumor. Pathological findings were consistent with a nonosseous cavernous hemangioma. MR imaging performed 5 years later was still normal.


CONCLUSIONS
The clinicoradiological and pathological features of this entity are described, and the literature reviewed.
