Fig 11. Nasopharyngeal carcinoma with infiltration of the prevertebral musculature, skull base, and cavernous sinus. A, Postcontrast fat-suppressed T1-weighted scan shows a large nasopharyngeal carcinoma, which demonstrates contrast enhancement of the prevertebral musculature on the left side (arrow). B, Note the growth through the foramen ovale (arrow) into the Meckel cave and cavernous sinus on the left side via cranial nerve V. C, The cavernous sinus extension on this axial postgadolinium fat-suppressed scan is well demonstrated (arrow). There may also be enhancement in the pterygopalatine fossa on the left side.
