Pulsatile tinnitus, hearing loss, and a number of patterns of cranial nerve palsies are commonly reported symptoms.
At the left petrous apex region, expanding the jugular foramen and extending into the left middle ear cavity, there is a vividly enhancing solid mass with elevated T2 signal and scattered flow-voids. The lesion has a subcentimeter protrusion abutting the cerebellum in the cerebellopontine angle. Partial obliteration of the mastoid air cells on the left.
Preserved left ICA flow-voids. Dural venous sinuses are patent, with normal opacification of the left sigmoid sinus and favourable torcular anatomy with good communication between both transverse sinuses.
