Case Reports Comparative Study
CT demonstration of pancreatic transection: a case report and comparison with other diagnostic modalities in the evaluation of blunt pancreatic trauma.
A case of prevertebral pancreatic transection demonstrated by pre-operative computed tomography is presented. The dramatic demonstration of pancreatic transection in this case suggests that CT scanning should be considered among the first-line modalities in the evaluation of suspected pancreatic injuries. In addition, the value of other diagnostic modalities in the evaluation of this disorder is reviewed.

Case Reports
Demonstration of unsuspected malignant disease of the pericardium by computed tomography.
Massive pericardial effusion associated with mediastinal neoplasm was first diagnosed by findings at computed tomography (CT) in two patients. In each case the CT findings prompted urgent pericardiocentesis for relief of pericardial tamponade. One of the patients was subsequently found to have a widely disseminated renal papillary adenocarcinoma, and the other had fibrosarcomatous mesothelioma of the pericardium. The role of CT in the diagnosis of pericardial disease is discussed.

The CT findings in patients with subarachnoid hemorrhage include visualization of the aneurysm (10% of the cases), subarachnoid, intraventricular, or intracerebral hemorrhage (87% of cases scanned within five days), "ischemic" lucency secondary to spasm (10%), and hydrocephalus (54%).

Coronal plane computed tomography (CT) is a valuable adjunct to standard transverse plane computed tomography in determining size and extension of intracerebral lesions. Extracerebral lesions at the skull base can also be evaluated by coronal plane CT. The appearances and diagnostic evaluations of these lesions, when used in conjunction with techniques to demonstrate bone detail, form the basis of this report.
