Abstract
A 50-year-old man with nasopharyngeal carcinoma was suspected to have progressive malignant disease because of an unexpected FDG-avid finding that was suspected to be neck lymph node metastasis on the follow-up FDG PET/CT after the definite anticancer therapy. However, after carefully correlating with the relevant MRI findings because of the atypical depth of the neck lesion and possible connection with the spinal nerve, the FDG-avid finding was reconsidered to be a tumor that originated from the nerve. The subsequent histologic examination confirmed the diagnosis of neurilemmoma. Copyright ? 2011 by Lippincott Williams & Wilkins.
