The CT venogram (with modified windows) confirm irregular erosion (moth-eaten) of the left jugular fossa, with a minimally heterogeneous enhancing mass that extends into the middle ear cavity at the cochlear promontory confirming a combined jugulotympanic paraganglioma. There is a left mastoid tip effusion. There is no venous sinus or jugular venous thrombosis.
There is a solitary punctate calcified granuloma within the left parietal lobe. There is incidental bi-maxillary antral mucosal thickening.
