MRI through the base of skull demonstrates an irregular mass located at the jugular foramen. It is of intermediate signal intensity on T1 and T2 weighted images with punctate regions of signal void (best seen on T2). Following administration of contrast, there is vivid contrast enhancement.
The mass contacts the internal carotid artery anteriorly almost encasing it, and posteriorly appears to have eroded into the posterior fossa.
There appears to have been prior right-sided surgery.
