Computed tomography of miscellaneous regional and diffuse small bowel disorders.

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.

Intramural vesicular fat--an uncommon CT finding.

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.

Radiographic demonstration of a wireless capsule pH monitor in the esophagus.

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.

Complications of abdominal and pelvic procedures: computed tomographic diagnosis.

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.
