Objective The purpose of this study was to evaluate and demonstrate the clinical and imagingfeatures of symptomatic duodenal diverticula presenting as or mimicking acute abdomen.Methods The imaging studies of 10 patients, all presenting with acute abdomen and diagnosedwith duodenal diverticula as the possible underlying cause, over a time period of 20 monthswere retrospectively analyzed.Results Eleven duodenal diverticula were depicted in 8 Multidetector Computed Tomography(MDCT) exams, 2 MRI-MRCP exams and in one intraoperative cholangiography. Acuteabdominal symptomatology resulting from duodenal diverticula was as follows: one patientpresented with perforation-diverticulitis, two patients with pancreatitis, one patient with acuteacalculous cholecystitis, four patients with biliary dilation and two patients with acute postprandialdiscomfort-pain. The mean maximal diameter of the diverticula examined was 2.67 cm (range0.96-4.98 cm). Further image analysis of the MDCT exams revealed that both the axial and thecoronal plane demonstrated the presence of the diverticula but the depiction of the diverticularneck was demonstrated in five cases in the axial plane and in all cases in the coronal plane.Conclusion Although duodenal diverticula constitute a rare cause of acute abdomen, carefulanalysis of imaging studies can aid to the identification of this uncommon factor of abdominalsymptomatology.Keywords periampullary/duodenal diverticulum, acute abdomen, imaging/diagnosisAnn Gastroenterol 2011; 24 (3): 192-199 (EN)
