Presentation transcript:

Contrast-agent–enhanced T1-weighted MR images (700/15) obtained in a 71-year-old man with skin cancer, who had TMJ tenderness and discomfort in the left ear. Contrast-agent–enhanced T1-weighted MR images (700/15) obtained in a 71-year-old man with skin cancer, who had TMJ tenderness and discomfort in the left ear. Symptoms related to V3 developed 8 months later.A, Axial image shows a parotid gland mass (T) that extends medially along the expected course of the auriculotemporal nerve (arrowheads) into the parapharyngeal space.B and C, Coronal images show the superior extension of the tumor along V3 (arrows in B) and middle meningeal artery (arrows in C) to involve the intracranial structures. Subtle dural enhancement is seen along the floor of the temporal fossa on the left (arrowheads in C). Note the normal appearance of V3 on the right. T indicates tumor. Image in C is slightly posterior to the image in B. Ilona M. Schmalfuss et al. AJNR Am J Neuroradiol 2002;23:303-311 ©2002 by American Society of Neuroradiology
