Case 15 - Recurrent squamous cell carcinoma of right orbit with extension to ophthalmic division and gasserian ganglion

This 68-year-old male had recurrent squamous cell carcinoma in the right supra-orbital area. This was treated with local excision, orbital exenteration, post-operative radiation therapy and chemotherapy. Recent follow-up MRI examination showed progression of the orbital lesion with perineural extension to the ophthalmic division of the trigeminal nerve and the gasserian ganglion. Patient was then treated with continuation of selective chemotherapy.
