Wegener granulomatosis invading the cavernous sinus: a CT demonstration.
A case of localized cranial Wegener granulomatosis was imaged with high resolution computed tomography. The mass extended from the infratemporal fossa, through the basal foramina, and into the cavernous sinus, causing complete occlusion of the internal carotid artery. Computed tomography demonstrated absence of bone destruction and a normal parotid gland and nasopharynx. Although uncommon, Wegener granulomatosis should be considered in the differential diagnosis of a parapharyngeal mass with intracranial extension.
