Ulnar neuropathy caused by a lipoma in Guyon's canal--case report.
A 74-year-old female presented with a 3-month history of compression neuropathy of the right ulnar nerve in Guyon's canal. Magnetic resonance imaging and ultrasonography revealed the location of the mass lesion. Surgical exploration discovered a lipoma pressing against both the ulnar nerve and the ulnar artery. The mass was extirpated. The postoperative course was uneventful with good function recovery.
