Giant colonic diverticulum is a rare entity first described in 1946 by Bonvin and Bonte. It may be congenital or acquired and the average age of presentation is 65. There are less than 150 reported cases in the literature. A large abdominal mass was detected during a routine physical examination in an 82-year-old man. CT scan showed a large air-filled mass, barium enema showed multiple sigmoid diverticula, but no communication with the mass was found. A diagnosis of giant sigmoid diverticulum was made, elective sigmoidectomy and resection of the diverticulum was performed with no complications. The clinical picture may be different, varying from asymptomatic to acute abdomen, intestinal perforation or fistula. It can be diagnosed with abdominal X-ray, CT scan, barium enema or MRI, but colonoscopy is not effective. There are two accepted theories of the pathophysiology of this entity: first, a congenital origin and second, that inflammatory diverticula are caused by a perforation with a ball-valve that allows gas to enter, but not to leave the cyst, thus, enlarging the false diverticulum, and progressively destroying the bowel layers, causing secondary fibrosis. Elective treatment is a segmental resection of the affected colon with the diverticulum and in cases of acute abdomen two-stage bowel resection is preferred.

Plain abdominal radiographs and barium studies are no longer the only available radiological methods for investigating alimentary tract disease. These basic procedures still retain their importance because of their cheapness, wide availability, and ease of performance. The newer modalities such as ultrasound, nuclear medicine, and computed tomography, however, have had a dramatic impact on the way in which common alimentary tract problems are routinely investigated in 1986. This presentation offers guidance in the investigation of acute abdomen, abdominal mass, peptic ulcer disease, right upper-quadrant pain, jaundice, altered bowel habit, and suspected pancreatic abnormality.

Jejunal diverticulitis is a rare condition that can present with an acute abdomen and be referred for imaging. We present the case of an elderly patient who at CT was diagnosed with an intra-abdominal abscess involving both jejunum and transverse colon. However, the underlying eitiology was not initially clear until small bowel barium follow-through.Pertinent points regarding CT findings in jejunal diverticulitis are discussed, and practical recommendations in small bowel diverticulum recognition and diagnosis are made.

We report 2 cases of pancreatic cancer discovered incidentally in the wake of acute abdomen from other causes. Case 1 is a 67-year-old man who was referred to our hospital in October 2010 for the treatment of an incarcerated right inguinal hernia. The hernia was manually reduced, and mesh plug hernioplasty was scheduled for the next day. A 2.9 cm diameter tumor was detected in the tail of the pancreas on plain CT at the first visit and confirmed on enhanced CT soon after the hernia repair. A follow-up abdominal CT scan approximately 1 month later showed modest enlargement of the tumor to 3.5 cm diameter. The patient underwent distal pancreatectomy with lymph node dissection in December 2010. The histopathological diagnosis was tubular adenocarcinoma(tub1>tub2). Comprehensive findings were pT2, pN0, cM0, fStage II . He was treated with adjuvant chemotherapy consisting of gemcitabine 1,000mg/m2 for 6 months after surgery, and at 5 years and 7 months after surgery, he was alive and recurrence-free. Case 2 is a 74-year-old man who presented to our hospital with lower abdominal pain and diarrhea in early January 2016. Colonoscopy and barium enema revealed severe stenosis of the rectum(Rs). Rectal biopsy confirmed adenocarcinoma of the rectum. In addition, an enhanced CT scan showed irregular dilatation of the pancreatic duct in the pancreatic tail. The patient underwent low anterior resection and distal pancreatectomy, which was performed following an intraoperative pancreatic ultrasound examination that supported a diagnosis of pancreatic cancer. Pathological and comprehensive findings of rectal cancer were tubular adenocarcinoma(tub2)and pT3, pN0, cM0, fStage II , and those of the pancreatic cancer were tubular adenocarcinoma(tub2)and pT1, pN0, cM0, fStage I . The patient was discharged from the hospital 46 days after surgery. However, he died 18 days later due to sudden out-of-hospital cardiopulmonary arrest.

Superior mesenteric artery syndrome, also known as Wilkie's Syndrome, is a life threatening clinical entity which developes as a result of obstructed second or third part of duodenum compressed between aorta and superior mesenteric artery. In this rare syndrome, a rapid weight loss is accompanied by stomach ache, abdominal distension, lack of appetite, nausea and vomiting after meals. In patients admitted for acute abdomen, superior mesenteric artery syndrome should be included in the differential diagnosis in case of a preceeding rapid weight loss. X-ray of barium passage, abdominal ultrasound, gastroscopy, abdominal angio-tomography or abdominal magnetic resonance angiography may be useful for diagnosis. Conservative and surgical approaches are available for the treatment. In this report we aimed to emphasize that superior mesenteric artery syndrome cases may admit for acute abdomen and that superior mesenteric artery syndrome should be included in differential diagnosis.

Radiological examination occupies a significant role, complementary to endoscopic studies, in the diagnostic process of inflammatory bowel disease (IBD). Both ulcerative colitis and Crohn's disease, due to multiple remissions and relapses, require repetitive examinations to evaluate the disease extent, severity, and response to pharmacological treatment. Whereas the use of barium contrast studies is progressively reduced, plain radiography confirms its utility as a first-line imaging tool for acute abdomen. Computed tomography remains an easily accessible and effective method to demonstrate disease activity and extraintestinal manifestations. However, the related radiation exposure reduces its applicability to urgent situations. Ultrasound and magnetic resonance, with the great advantage of avoiding ionising radiation, are highly recommended to present the complications of IBD. Use of oral and intravenous contrast in computed tomography enterography and magnetic resonance enterography demonstrates IBD involvement in the small intestine wall, which is difficult to assess in other radiological and endoscopic examinations.
