Gallstone ileus demonstrated by CT.

OBJECTIVE: The appearance and evolution of gallstone ileus as seen by CT are reported. MATERIALS AND METHODS: CT examination was performed on three patients with unspecific abdominal pain. In one patient sequential investigations were performed over 7 months. RESULTS: In all cases the gallbladder was greatly distorted, contained air, and was in direct continuity with a thickened duodenal wall. The gallstone was detected in the small bowel in all cases. In one patient sequential CT examinations over several months demonstrated the evolution from uncomplicated gallstone disease to cholecystitis and finally to perforation of the gallstone into the duodenal bulb. CONCLUSION: Awareness of the CT findings in gallstone ileus may result in more rapid diagnosis and treatment, which may lead to a decrease in the rather high morbidity and mortality seen in this disease.

Radiography of pressure ulcers.

In patients with longstanding and/or deep pressure ulcers radiology is usually consulted. Survey radiography and sinography in 14 patients with pressure ulcers (6 over the tuber ischii and 8 over the femoral trochanter) were evaluated. Osteomyelitic involvement of adjacent bone was revealed in 9 patients on survey radiography. However, it was usually impossible to assess whether or not bony involvement represents healed or active osteomyelitis. Sinography did not contribute to the assessment of whether or not adjacent cortical bone was involved. However, when a fistulation to an adjacent joint was revealed this contributed substantially to the preoperative planning of resection. We therefore recommend that survey radiography and sinography should be included in the evaluation of these patients but that the results from such examinations are critically evaluated. Joint involvement should be taken seriously as progression of septic arthritis usually occurs rapidly.
