Case ReportsPneumatosis intestinalis: role of computed tomography in diagnosis and management.
Four patients with pneumatosis intestinalis (PI) demonstrated by computed tomography are presented. Computed tomography delineated the location and extent of PI more accurately than plain abdominal radiographs and demonstrated any coexisting abdominal pathology. ⋯ In one patient PI would have been overlooked entirely using only conventional abdominal window settings. This technical observation could have potential clinical significance in the investigation of patients with suspected intestinal ischemia or gangrene where the appearance of intramural air is an ominous prognostic sign.

Coronal nuclear magnetic resonance (NMR) imaging of the abdomen at 0.5 tesla.
Coronal nuclear magnetic resonance (NMR) abdominal imaging was performed on a normal volunteer. The scan technique and anatomic features are described. Coronal abdominal scanning optimizes vascular imaging in the abdomen and is helpful in defining the anatomic relationships of a variety of structures.

Six patients with clinical features suggestive of Tietze syndrome had a thoracic computed tomographic (CT) examination following a normal plain film or tomographic examination (or both) of the affected costochondral junction. A chest wall mass was excluded in all six patients. The CT findings included enlargement of the costal cartilage at the site of complaint (two patients), ventral angulation of the involved costal cartilage (two patients), and normal anatomy of the costochondral junction (two patients). Exclusion of a chest wall mass by CT may obviate the need for operative intervention.

A case of Whipple disease demonstrated on computed tomography (CT) a large mesenteric mass of low density and thickened folds in the jejunum, which was confirmed by barium studies. Retroperitoneal manifestations were absent. The importance of CT in demonstrating the extraintestinal manifestations of Whipple disease is emphasized.

Case ReportsValue of computed tomography for the diagnosis of a ruptured eye.
The diagnosis of scleral perforation of the globe following ocular trauma is often obvious on physical examination, but occult perforations occur frequently. In addition to locating intraorbital foreign bodies and associated facial bone fractures, computed tomography of the orbit can suggest an occult scleral rupture. Posterior collapse of the sclera causes flattening of the posterior contour of the globe, the "flat tire" sign. Other associated findings that are suggestive of scleral rupture are intraocular foreign body or gas, thickening of the sclera posteriorly, and a blood-vitreous fluid-fluid level.
