Imaging of peripheral nerve lesions in the lower limb.

Lower limb peripheral neuropathy may have a variety of causes. This article focuses on focal neural lesions because of neural entrapment associated with static mechanical compression or dynamic compression/stretching. Mechanical compression may relate to direct blunt trauma, surgical injury, mass effect associated with adjacent mass lesions, and frictional effects associated with fibrous bands.

MR imaging of traumatic and overuse injuries of the wrist and hand in athletes.

Traumatic and overuse injuries of the hand and wrist are common in athletes. Increasingly, MR imaging is being used to complement clinical and radiographic assessment in the diagnosis and management of these injuries. MR imaging is able to image accurately the bones, tendons, ligaments, nerves, and other small structures of the hand and wrist.

Overuse and impingement syndromes of the shoulder in the athlete.

Overuse and impingement syndromes in the shoulders of athletes are predominantly caused by instability of the glenohumeral joint. Glenohumeral joint instability is usually acquired from repetitive overuse of the rotator cuff and shoulder girdle muscles, or injury of the static and dynamic stabilizers of the glenohumeral joint. Congenital hypermobility of the joint may also contribute to these syndromes in some individuals.

A "paneful" perforation.

Radiographs of a woman presenting with abdominal pain revealed a large foreign body within the pelvis. A diagnosis of perforation of the colon was made, and at laparotomy an 8.5 cm long glass fragment was removed from the bowel.

Percutaneous gelfoam embolization of chronic enterocutaneous fistulas: report of three cases.

Purpose: A relatively simple radiologically guided method for the treatment of enterocutaneous fistula by gelfoam embolization is described.

Methods: Three cases of chronic enterocutaneous fistula are presented. In each case, a sheath was positioned with its tip at the enteric opening of the fistula.
