Diagnosis of ganglion in Guyon's canal by magnetic resonance imaging.
Compression of the ulnar nerve at the wrist can be caused by a multitude of intrinsic and extrinsic factors. The exact diagnosis and location of compression can frequently be difficult to determine. Magnetic resonance imaging can be a useful method in diagnosing the cause and location of ulnar nerve compression. A case is presented of ulnar nerve compression caused by a ganglion in Guyon's and diagnosed preoperatively by magnetic resonance imaging.
