An intensely enhancing well-defined soft tissue mass lesion is seen centred upon the left jugular fossa causing widening and moth-eaten erosions of the jugular foramen. It shows extension into the middle ear cavity hypotymanum abutting the cochlear promontory. The mass is seen eroding the posterior wall of the left carotid canal and slightly abutting the left internal carotid artery. It is seen inseparable from the left jugular vein with no evidence of transverse, sigmoid or jugular vein thrombosis.
