Consecutive instances of gallstone ileus due to obstruction first at the ileum and then at the duodenum complicating a gallbladder carcinoma: a case report.

Ectopic gallstone obstruction, gallstone ileus, due to cholecystoenteric fistula is an infrequent condition. Its occurrence as a complication of a gallbladder (GB) carcinoma is even more rare. We describe an unusual case of a GB carcinoma complicated by a cholecystoduodenal fistula leading to first gallstone obstruction in the ileum and then, later, in the duodenum, in which an accurate preoperative diagnosis was based on pathognomonic computerized tomography (CT) features. A correct diagnosis of this may be crucial and requires prompt surgical intervention; radiologists should be familiar with their classic CT appearance.

Congenital internal hernia as a cause of small bowel obstruction: CT findings in 11 adult patients.

The aim of this study is to report the CT findings in patients proved to have congenital internal hernia (CIH) as a cause of small bowel obstruction (SBO). The CT scans of 11 patients (9 men and 2 women, with ages ranging from 20 years to 95 years (mean 60.7 years), presenting with clinical symptoms and signs of SBO without previous abdominal surgery or trauma, were retrospectively reviewed. In all patients features of SBO were seen. In addition, in nine of them a saclike mass, containing dilated small bowel loops with mesenteric vessels converging toward its orifice was demonstrated and a pre-operative diagnosis of an incarcerated internal hernia was suggested. In the other two, a closed loop obstruction was seen without an identifiable cause. Mural thickening of the entrapped loops within the hernial sac was seen in five patients, with hypoperfusion in four of them, blurring of the mesenteric vessels with localized mesenteric fluid was demonstrated in seven and free peritoneal fluid in 10. All patients were operated on following the CT and an incarcerated CIH was confirmed. Gangrenous bowel was present at exploration in seven cases. One patient died. In conclusion, in patients with intact abdomen and SBO, CT may be the first imaging modality to discover a clinically unsuspected CIH, which requires prompt surgical intervention. Radiologists should be aware of the CT features suggestive of a SBO caused by CIH, i.e. a saclike mass of dilated small bowel loops, as a correct diagnosis will influence patient management and prognosis.

Small bowel obstruction related to left-side paraduodenal hernia: CT findings.

The role of computed tomography in the evaluation of patients with small bowel obstruction has been extensively described in the current literature. We report a rare case of small bowel obstruction related to a surgically proved left-side paraduodenal hernia detected on abdominal computed tomography.

Pictorial review. CT of duodenal pathology.

This pictorial review presents the CT findings in different pathological entities of the duodenum. The aim of the article is to demonstrate the contribution of a common imaging modality, i.e. abdominal CT, in the diagnosis of various duodenal disorders.
