Abstract
Compression of the ulnar nerve in Guyon's canal leads to Guyon's canal syndrome. Lipoma is a rare cause of such compressions with only 12 cases reported previously. We report a 55-year-old man who presented with swelling in the left hand with decreased sensation in the ring and little fingers. Magnetic resonance imaging revealed high signals in T1-weighted and T2-weighted images with suppression of the short T1 inversion recovery signal, suggestive of lipoma. On exploration a well-encapsulated, dumbbell-shaped, fatty tumor was seen in the hypothenar space and Guyon's canal. The tumor was enucleated in toto. At 6-month follow-up, the patient had fully regained sensation. A review of the literature is presented for similar cases where a lipoma was the cause of Guyon's canal syndrome.
