Benign triton tumor of the trigeminal nerve.
Benign triton tumors (neuromuscular hamartomas) are rare neoplasms composed of well-differentiated striated muscle fibers admixed with peripheral nerve fibers. To the best of our knowledge, this is the third case reported in the world literature of a benign triton tumor involving cranial nerve V (trigeminal nerve) and the first in the radiology literature. The previous reports of this lesion have focused on its unusual pathology and not on the imaging findings. In light of the imaging appearance of this lesion, we consider that the imaging findings may suggest this uncommon diagnosis.
