Commentary [Trigeminal Amyloidoma: Case Report and Review of the Literature]

The authors have described a rare condition involving the lateral wall of the cavernous sinus and trigeminal nerve. Because of the patient's symptoms and the location involved, the lesion could be mistaken for a trigeminal schwannoma or chondrosarcoma. However, the radiological features appeared to be quite distinct-the lesion was hypointense or isointense on T2-weighted MRI, in contrast to these other two tumors. The authors' strategy of extraneural resection and nerve decompression appears to be a good one, especially if the diagnosis can be made by frozen section, and the tumor is distinguished from malignant lesions such as adenoid cystic carcinoma.
