RESUMEN
This article reviews the computed tomography (CT) findings of miscellaneous regional and diffuse small bowel disorders. CT technique and potential pitfalls are discussed. Several categories of regional and diffuse small bowel conditions are reviewed, with representative CT images. These disorders often have relatively nonspecific CT appearances, and correlation with the history, clinical, and laboratory findings in each specific case is critical. In selected conditions, the CT findings are highly specific. The imaging literature of some of the common as well as some of the less common entities is reviewed, and clues to narrowing the differential diagnosis are provided.

We present a case of a 75-year-old male who presented with lower back pain found to have an incidental finding of intramural vesicular fat on an unenhanced computed tomography of the pelvis. This relatively uncommon finding of a normal entity should not be mistaken for other causes of pathology within the urinary bladder.

Monitoring of esophageal pH is a major component of the evaluation of gastroesophageal reflux disease. A recent innovation has led to the replacement of the intraluminal probe by a wireless capsule. This capsule is attached to the esophageal wall and transmits the appropriate data to a patient-worn receiver. After a short period of time the capsule detaches itself from the wall and is eliminated. We recently encountered a patient in which the capsule did not detach in a timely manner. It was imaged during a preoperative esophagogram.

The postprocedural period is a critical time in which serious complications can manifest. Localization of suspected complications following abdominal and pelvic procedures can be difficult on clinical evaluation alone. For example, abdominal pain after a colonoscopy may vary in etiology and can result from simple colonic spasm to colonic perforation, hemoperitoneum, or even splenic rupture. Vague abdominal pain following a renal biopsy may be due to minimal postprocedural bleeding into and around the kidney or may be due to potentially life-threatening hemorrhage. In such patients, computed tomography can play a crucial role in the rapid identification of complications as well guidance of subsequent patient management. The purpose of this article is to demonstrate the benefit of computed tomography-assisted diagnosis of complications associated with routine procedures performed on or throughout the abdomen and pelvis, including cardiac catheterization, colonoscopy, endoscopy, percutaneous biopsy, and interventional radiology procedures.
