Radiological appearance of the ampulla of Vater.

The localized dilatation below the confluence of the bile and pancreatic ducts is known as the ampulla of Vater. The purpose of the present study was to delineate the radiological features of the choledochopancreaticoduodenal junction, with special reference to ampullar formation in this region. This was done by specimen radiography and review of the films from 255 examinations with endoscopic retrograde cholangiopancreatography. Full evaluation was possible in 200 cases. Ampullar dilatation was observed in only 9 (5.1%) of the 175 patients with a common terminal opening. No ampullar dilatation was observed in the 25 patients with separate openings of the duct. The appearance in the presence of ampullar dilatation is described. The distal end of the common bile duct, below its confluence with Wirsung's duct, has been known as the ampulla of Vater for nearly 130 years. This is a most important diminutive region of the human body, but there is little in the literature concerning its radiological presentation. In this report a radiological study is presented on the choledochopancreaticoduodenal junction.

Calcifications of the palatine tonsillary region: CT demonstration.

The scans of 100 consecutive patients referred for computed tomographic examinations that included the oropharynx were reviewed with regard to calcifications of the palatine tonsillary region. Calcifications were found in 20% of the female patients and 13% of the male patients. Ten patients had one calculus, and six had two or more. The sizes of the calculi ranged from 1 to 7 mm. Tonsillary calculi must be included among the diagnostic possibilities when survey radiographs of the neck show soft-tissue calcifications.

The early manifestation of Yersinia colitis demonstrated by the double-contrast barium enema.

A 19-year old female with a bloody, diarrheal illness of acute onset where Crohn's disease primarily was suspected is presented. The double - contrast barium enema revealed multiple, diffusely scattered aphthous erosions of the colonic mucosa: the rectum was scarcely affected. Biopsies taken by endoscopy demonstrated nonspecific inflammatory changes of the mucous membrane. However, routinely taken stool cultures revealed an infectious colitis due to Yersinia enterocolitica. Our case demonstrates the necessity to consider Yersinia enterocolitis in the radiographic differential diagnosis when the diagnosis of Crohn's disease or ulcerative colitis seems obvious.

Carcinoid infiltration and fibroplastic changes of the mesentery as a cause of malabsorption.

The presentation of carcinoid involvement of the mesentery is described, with clinical manifestation of severe malabsorption: angiographically it resembled retractile mesenteritis. The special biologic activity of the carcinoid cells inducing fibroblastic activity with secondary alterations of vascular, lymphatic and neural structures of the mesentery is discussed in relation to the altered physiology and morphology of the intestine, causing the clinical picture of sprue.

The angiographic features of tumor infiltration of the greater omentum.

The angiographic findings of a metastatic neoplasm of the greater omentum are presented, and a survey of the angiographic features of previously reported omental tumors, primary and metastatic, is given. The angiographic pattern seems to be quite uniform with no specific relation to the histologic origin of the tumors and angiography is probably at the present time the best diagnostic modality.

Pancreatic cystadenoma. Angiographic and histologic findings illustrated by two cases.

Two cases of pancreatic cystadenoma are presented, demonstrating the typical angiographic and histologic pattern as given in previous literature. Although computed tomography and ultrasound examinations may be useful [11], angiography seems to play a decisive role in establishing the diagnosis, demonstrating the localization and extent of the tumor, and permitting the possible differentiation of benign and malignant lesions.
