RADIOLOGY OF THE SMALL-INTESTINE

Vascular diseases affecting the small intestine received considerable attention in the literature this year. Computed tomography, ultrasonography, and magnetic resonance imaging are capable of replacing angiography in detecting venous thrombosis and in following the response of the thrombus to therapy. Ischemic bowel injuries are described in patients with vasculitis, blunt trauma, and cocaine use. Two large series have shed light on effective approaches to the radiologic evaluation of patients with hemorrhage from a small bowel source. Computed tomography continues to be explored as a useful technique for detecting and evaluating small bowel obstruction. Studies from the Department of Radiologic Pathology at the Armed Forces Institute of Pathology review the features of two rare, benign, intestinal, neoplastic conditions: Peutz-Jeghers syndrome and inflammatory fibroid polyps.
