BACKGROUND & AIMS The treatment of patients with extensive pancreatic necrosis remains controversial; a subpopulation of patients with extensive acute pancreatic necrosis develop complex, organized collections. This study examined the feasibility of endoscopic drainage in patients with extensive organized pancreatic necrosis. METHODS Eleven patients with(More)
Computed tomography (CT) is a highly accurate method of detecting and clarifying the nature of space-occupying lesions within the liver. Obstructive (surgical) jaundice can be differentiated from nonobstructive (medical) jaundice very accurately using CT scanning; when obstruction is present, its level and cause can often be diagnosed. CT is not a sensitive(More)
The authors analyzed the clinical and CT findings in 100 normal subjects and 31 patients with gastric disease to determine the significance of thickening of the gastric wall. Ninety per cent of the normal individuals had a wall thickness less than 1 cm with adequate distension of the lumen. Twenty-nine of the 31 patients with gastric disease (94%) had a(More)
The radiologic findings of acute focal bacterial nephritis in 13 patients are described. These include (1) focal swelling or mass on excretory urogram; (2) solid mass, often with echo amplitude lower than adjacent normal renal cortex on sonography; and (3) a poorly marginated, low density mass that exhibits patchy and inhomogeneous enhancement after(More)
The CT appearance of dilated hepatic lymphatics in liver transplant recipients has been described recently. We have observed similar findings of presumed hepatic lymphatic dilatation and perivascular lymphedema in 20 patients seen over an 8-month period, none of whom had received a liver transplant. Review of these patients' records showed that 18 (90%) of(More)
Spontaneously developing intrahepatic portal vein gas is usually associated with necrotic bowel, bacteremia, or both. Very few patients with this radiographic sign survive. A postoperative patient with severe abdominal pain and distention was found to have hepatic portal vein gas. At exploration two intraperitoneal abscesses were found and drained. The(More)
As CT is often the initial imaging method in the evaluation of suspected complications of abdominal aortic aneurysm, especially rupture of the aneurysm, it is important to be aware of other less common complications that can be detected by CT. A patient with an aortocaval fistula and renal venous hypertension is discussed. The constellation of CT findings(More)
Computed tomography (CT) easily and accurately demonstrates both the normal and abnormal adrenal gland. The normal adrenal gland can be seen in almost 95% of patients. With this technique, 29 of 29 proved adrenal masses were demonstrated; one case of bilateral adrenal hyperplasia could not be recognized, another showed equivocal enlargement. CT is an(More)
113 cases of pancreatic and renal disease studied by both ultrasound and computed tomography (CT) were analyzed retrospectively. CT provided a diagnosis when pancreatic ultrasound was unsuccessful due to overlying bowel gas or obesity and when renal ultrasound was unsuccessful due to obesity, reverberations from ribs, small lesions, or multiple lesions.(More)
