Computed tomographic and angiographic demonstration of gastroduodenal artery pseudoaneurysm in a pancreatic pseudocyst.

The complementary use of computed tomography and angiography in two patients with bleeding gastroduodenal artery pseudoaneurysm associated with pancreatic pseudocyst is presented.

The posterior pararenal space: an escape route for retrocrural masses.

In two patients with retrocrural tumors, dissection of the tumors selectively into the posterior pararenal space was observed by computed tomography. Cadaver studies confirmed the presence of potential communications between the retrocrural space and the extrapleural space of the thorax or the posterior pararenal space of the abdomen.

Localization of the head of the pancreas using the junction of the left renal vein and the inferior vena cava.

The junction of the left renal vein with the inferior vena cava is visualized on most computed tomography studies of the abdomen. This junction is a useful guide in localizing the pancreatic head, just as the superior mesenteric artery is used to localize the body of the pancreas.

A simple method of localizing the level of computed tomography cross sectioning.

Before computed tomography (CT) scanning, a preliminary radiograph of the area of interest is obtained with a Bell-Thompson ruler on the table top parallel to the spine. This allows precise localization of the level of CT sectioning in relation to the vertebral column.

Lack of visualization of the portal venous tree in cirrhosis of the liver: a computed tomography finding with possible diagnostic significance.

During computed tomography (CT) scanning of the liver, the inferior vena cava can be identified as a separate structure of lesser density adjacent to the caudate lobe in two-thirds of patients without known hepatocellular disease. In patients with alcoholic (portal) cirrhosis of moderate to severe degree, intrahepatic portal veins may not be identified on CT scans, even though their inferior vena cavas can be definitely distinguished from the caudate lobe. Portal cirrhosis causes distortion and obliteration of the portal triads, which is presumably reflected by lack of visualization of intrahepatic portal veins during CT scanning.

Visualization of the longitudinal fold of the duodenum by computed tomography.

The longitudinal fold of the duodenum can be visualized by computed tomography (CT). Visualization of the fold helps localize the hepatopancreatic duct entrance into the duodenum. Many pathological processes of the head of the pancreas such as pancreatitis or malignancy can produce swelling involving the longitudinal fold, which can be visualized by CT.

Subdiaphragmatic adiposity mimicking ascites by liver-lung scintigraphy.

A case is reported in which abnormal liver-lung scintigraphy mimicking ascites was secondary to subdiaphragmatic fat.
