Squamous cell carcinoma involving trigeminal nerve, second division
Presentation
Squamous cell carcinoma of the face.
Patient Data
An enhancing soft tissue mass is seen in the left infraorbital foramen, extending along the course of V2 back to the cavernous sinus from the facial squamous carcinoma.
Case Discussion
The findings are compatible with perineural spread of the patient's squamous cell carcinoma. Fat suppression may help the conspicuity of subtle enhancement, especially in the optic nerve. At high field strengths, susceptibility artifacts from the tissue-gas interface at the margins of the maxillary sinus may actually be a hindrance if CHESS fat suppression is used to look at the V2 nerve.
