We report an unusual case of an amyloidoma of the gasserian ganglion associated with trigeminal neuralgia. MR imaging showed a mass in Meckel's cave, which was isointense with surrounding tissue on T1-weighted images and hypointense on T2-weighted images. After contrast administration, the mass enhanced homogeneously, and thin cuts through the region showed involvement in the expected location of the gasserian ganglion and, more laterally and inferiorly, in the proximal part of V1. A review of the literature revealed that only one similar case has been reported since the advent of modern neuroimaging. Amyloidoma, although rare, may be considered as a rare differential diagnosis of a mass in this region.

UI	MeSH Term	Description	Entries
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D012668	Trigeminal Ganglion	The semilunar-shaped ganglion containing the cells of origin of most of the sensory fibers of the trigeminal nerve. It is situated within the dural cleft on the cerebral surface of the petrous portion of the temporal bone and gives off the ophthalmic, maxillary, and part of the mandibular nerves.

D017772	Amyloid Neuropathies	Disorders of the peripheral nervous system associated with the deposition of AMYLOID in nerve tissue. Familial, primary (nonfamilial), and secondary forms have been described. Some familial subtypes demonstrate an autosomal dominant pattern of inheritance. Clinical manifestations include sensory loss, mild weakness, autonomic dysfunction, and CARPAL TUNNEL SYNDROME.
