Aneurysms of the portal vein and superior mesenteric vein

Abstract. Only scattered reports of portal vein and superior mesenteric vein aneurysms appear in the literature. Case reports of three patients with portal vein and superior mesenteric vein aneurysms diagnosed by computed tomography (CT) and gray-scale, color Doppler, and duplex Doppler sonography are presented. In one case, an isolated portal vein aneurysm was demonstrated. In the second case, an aneurysm of the portal vein and superior mesenteric vein resulting in biliary ductal dilatation was observed. In the third case, an isolated superior mesenteric vein aneurysm was found. None of the patients had a history or clinical evidence of underlying liver disease, pancreatitis, or other disease states that would predispose them to the development of aneurysms. The clinical presentations, possible etiologies, and imaging features of portal vein and superior mesenteric vein aneurysms are reviewed. The value of CT and sonography in the detection and characterization of these rare aneurysms is discussed.

Iatrogenic intubation injuries of the upper gastrointestinal tract in adults

Perforation of the hypopharynx, esophagus, and stomach complicated the insertion of flexible tubes in 11 adults. Nasogastric suction tubes were responsible for 5 instances of gastric perforation. Palliative intubation of obstructive carcinomas of the distal esophagus resulted in delayed perforation of the esophagus and stomach in 2 cases. The use of a Linton tube for decompression of bleeding varices caused esophageal rupture in 1 patient whereas 2 others developed pharyngoesophageal perforation due to misplaced endotracheal tubes. The remaining 1 case demonstrated penetration of a chest tube into the esophageal lumen. The radiographic features and mechanisms of these iatrogenic injuries are described and the pertinent literature is reviewed.

Esophageal intramural pseudodiverticulosis.

Esophageal intramural pseudodiverticulosis (EIP) is a rare condition of unknown etiology. It is characterized by multiple, small, flaskshaped outpouchings in the esophageal wall. Involvement may be segmental or diffuse. Since this entity was first reported in 1960, there have been 43 cases described in the English literature. These cases are reviewed and six additional cases are reported with emphasis on clinical and radiographic parameters of this entity.

Magnetic resonance pancreatography (MRP).

Magnetic resonance pancreatography (MRP) is a technique that permits accurate evaluation of the pancreatic duct without instrumentation, contrast material administration, or ionizing radiation. Because MRP is entirely noninvasive, MRP avoids complications associated with endoscopic retrograde pancreatography (ERP) such as pancreatitis and perforation. MRP allows for the noninvasive evaluation of patients with acute and chronic pancreatitis, variant anatomy of the pancreatic duct, pancreatic duct trauma, and pancreatic neoplasia. MRP yields diagnostic information in the setting of a failed or incomplete ERP. When MRP is performed in conjunction with conventional abdominal MR, the result is a comprehensive examination of the pancreatic duct as well as the pancreas and other solid organs of the abdomen.

Benign diseases of the biliary tract: Evaluation with MR cholangiography

MR cholangiography (MRC) is a noninvasive, rapid means of evaluating the biliary tract that, in many instances, may replace invasive procedures such as diagnostic endoscopic retrograde cholangiography and percutaneous transhepatic cholangiography. This article describes and illustrates the MRC features of benign diseases of the biliary tract such as choledocholithiasis; intrahepatic bile duct calculi; congenital anomalies, including aberrant bile ducts and choledochal cysts; postsurgical strictures; and strictures related to chronic pancreatitis.

Right lower quadrant pain: Imaging with computed tomography

Computed tomography (CT) is a fast and accurate way to evaluate patients with acute right lower abdominopelvic pain. In the emergency setting, appendicitis is the most common etiology. A tailored CT examination can visualize the normal or abnormal appendix with accuracy, confirming or excluding appendicitis in 90–95% of cases. If the appendix is normal, CT often identifies an alternative etiology for the pain. This exhibit reviews the CT appearance of the normal appendix, usual and unusual presentations of appendicitis and complicated appendicitis, and pitfalls in diagnosis. The CT appearance of other conditions included in the differential diagnosis of acute right lower quadrant pain and clinically mimicking appendicitis is also presented, including disorders arising from the gastrointestinal tract, genitourinary tract, and vascular and musculoskeletal systems.
