Lipomatosis of Nerve: More than a Focal Distal Disease.

Lipomatosis of nerve is a rare, ill-defined, fibrofatty tumor intermingled among nerve fascicles. The classic presentation of lipomatosis of nerve describes focal distal involvement of the median nerve at the wrist. The purpose of this study was to determine the level of proximal lesion extension in cases of upper extremity lipomatosis of nerve using magnetic resonance imaging.

Musculoskeletal sonography of the postoperative orthopedic patient.

Musculoskeletal sonography has an important role in the evaluation of the postoperative orthopedic patient. One major advantage of sonography over magnetic resonance imaging and computed tomography is that artifact from metal, which is common after orthopedic surgery, is relatively limited. This allows a clear assessment of the soft tissues for abnormalities such as tendon tear, tenosynovitis, joint effusion, and soft tissue infection.
