MRI images demonstrating extensive, strongly enhancing nasopharyngeal mass lesion with numerous flow voids. There is extension into the left infratemporal fossa with remodeling of the posterior wall of the maxillary sinus, as well as intraorbitally through the left inferior orbital fissure and orbital apex, with compression the left optic nerve. There are erosive changes in the skull base with intracranial/extradural extension in both the anterior and middle cranial fossa. In addition, there is elevation of the pituitary gland and compression of left cavernous sinus, associated with encasement of the ICA cavernous segment, the later shows however preserved flow void.
On the TOF angiography, left maxillary artery appears to be the main feeder of this mass in the infratemporal fossa with marked enlargement of its anterior branch.
Overall, findings consistent with juvenile nasopharyngeal angiofibroma.
