Small bowel diverticulitis - Spectrum of CT findings and review of the literature

A Case of Uncomplicated Duodenal Diverticulosis Presenting With Right Upper Abdominal Pain

Small bowel diverticulosis is not a common disease entity; however, it is increasingly diagnosed and linked to various gastrointestinal complaints. Although rare, complications can occur and may sometimes require surgical or endoscopic intervention. Furthermore, suspecting and diagnosing duodenal diverticulosis (DD) can be challenging due to the variety of presenting signs and symptoms. Much of our current knowledge comes from case reports and series. This report aims to document a case of DD presenting with severe right upper quadrant pain mimicking the signs and symptoms of acute cholecystitis. It also reviews and summarizes the available literature on the clinical manifestations of DD, its diagnostic approach, treatment modalities, and possible complications encountered in the ED.

Left side jejunal diverticulitis: US and CT imaging findings

Small bowel jejunoileal diverticulosis is an uncommon and usually asymptomatic condition. Complications may occur such as acute diverticulitis including infection or perforation, bleeding, small bowel obstruction and volvulus. Herein we report a case of a 76 years-old woman with acute left side abdominal pain and tenderness. A clinical suspected diagnosis of colonic diverticulitis was formulated. She underwent Ultrasound that revealed a collapsed small bowel loop with a large sac-like out-pouching lesion with mixed content (fluid and pockets of air) associated to hyperechogenicity of perilesional fat. Because of the atypical US findings, the patient underwent abdominopelvic CT that confirmed that the large sac-like out-pouching was a jejunal inflamed diverticulum. The patient underwent emergency surgery. Radiologist should be aware of imaging findings of jejunoileal diverticulitis in order to achieve a prompt diagnosis.

Acute Abdomen Secondary to Ileal Diverticulum: A Case Report

Small-bowel diverticulosis is rare. We report the case of a male with an acute abdomen secondary to an ileal diverticulum. A 46-year-old male complained of progressive abdominal pain over 24 hours of evolution in the left flank. On physical examination, we found abdominal pain in the left flank and mesogastrium, tenderness, and signs of peritonitis. The simple abdominal CT showed a heterogeneous tubular image in the small bowel. We performed a diagnostic laparoscopy and found a normal cecal appendix. There was no free abdominal fluid or adhesions, and the colon was without diverticula. We found a single diverticulum of 4 cm in length and 2 cm in diameter in the small intestine and therefore converted the procedure to a laparotomy. We performed a bowel resection including the diverticulum and intestinal anastomosis. The patient reported remission of symptoms after surgery.

Imaging spectrum of non-neoplastic and neoplastic conditions of the duodenum: a pictorial review

Given its crucial location at the crossroads of the gastrointestinal tract, the hepatobiliary system and the splanchnic vessels, the duodenum can be affected by a wide spectrum of abnormalities. Computed tomography and magnetic resonance imaging, in conjunction with endoscopy, are often performed to evaluate these conditions, and several duodenal pathologies can be identified on fluoroscopic studies. Since many conditions affecting this organ are asymptomatic, the role of imaging cannot be overemphasized. In this article we will review the imaging features of many conditions affecting the duodenum, focusing on cross-sectional imaging studies, including congenital malformations, such as annular pancreas and intestinal malrotation; vascular pathologies, such as superior mesenteric artery syndrome; inflammatory and infectious conditions; trauma; neoplasms and iatrogenic complications. Because of the complexity of the duodenum, familiarity with the duodenal anatomy and physiology as well as the imaging features of the plethora of conditions affecting this organ is crucial to differentiate those conditions that could be managed medically from the ones that require intervention.
