ABSTRACT
Magnetic resonance imaging was used to assess nine median nerves in the wrists of seven patients who had signs and symptoms of persistent compressive median neuropathy despite previous carpal tunnel release. Intraoperative findings were then correlated in eight surgically treated cases with both MRI findings and postoperative results. Magnetic resonance imaging suggested a potential abnormality in each of eight operative cases. These findings correlated very well with both intraoperative observations and postoperative results, which indicated that some abnormality involving either the median nerve or the transverse carpal ligament had been present in all cases. Magnetic resonance imaging proved to be a sensitive and specific tool in the evaluation of persistent postoperative median nerve compression.

The value of gray scale ultrasound in evaluating primary diseases of the abdominal aorta and peripheral vessels has been well documented. However, only limited attention has been given to complications associated with arterial graft surgery. Twelve patients with a variety of complications are reported. These include 10 anastomotic pseudoaneurysms, one abscess, two "aneurysms" in degenerated graft material, and four serous fluid collections around intact Dacron grafts. The latter two complications are previously unreported.

The accuracy of ultrasonic cholecystography is well established. However, oral cholecystography remains the primary screening examination. Ultrasonic and oral cholecystograms were performed in 100 consecutive patients to determine if ultrasound could be used as a primary screening procedure, particularly in patients with acute right-upper-quadrant pain, suggestive of acute cholecystitis. Ultrasound compared favorably with oral cholecystography in accuracy and specificity. It was also cost-effective, saving one to two days of hospitalization.

Intra-abdominal abscess formation is a common complication of ruptured and gangrenous appendicitis. The signs and symptoms associated with abscess formation are generally nonspecific and may be seen without a collection, which is amenable to surgical drainage. Because such patients are quite fragile, it is essential to use a diagnostic test which is noninvasive and highly accurate prior to further operation. B-scan ultrasound fulfills these requirements and is particularly valuable in assessing the recurrence of abscesses and in detecting wound abscesses.

B mode ultrasound can be used to evaluate intrathoracic masses that contact the chest wall. It provides a noninvasive technique to distinguish cystic from solid lesions and to assess the internal structure. Four cases are reported in which this procedure was used to provide diagnositc information.

The authors describe the ultrasound appearance of cystadenoma of the pancreas. Such lesions may be characterized as sonolucent, with good through-transmission, slightly irregular but well-defined margins, and internal echoes from septa.

Localized cutaneous as well as unifocal and multifocal systemic sporotrichosis may all produce roentgenographic findings. Localized cutaneous nodules may occasionally extend to the bone below producing a locally erosive lesion similar to those more commonly found in blastomycosis. More frequently, sporotrichosis involves the joints, either alone or with accompanying skin nodules. The joint changes are those of a pyogenic arthritis of the knees, elbows, hands, or feet which is difficult to distinguish from pyarthrosis produced by other organisms. The pulmonary findings depend upon whether or not the lung is the only site of infection. If there are no other areas of involvement, the pulmonary findings may be indistinguishable from those of secondary tuberculosis. However, if the skin on joints are also involved, small nodules appear and apparently do not proceed to cavitation.
