Signal intensity on T1-weighted magnetic resonance images provides highly useful diagnostic information on mucinous cystic tumors of the pancreas. Furthermore, tumors may be classified into two groups according to the type of epithelial lining.
BackgroundChronic mesenteric ischemia (CMI) is a rare disease; however, symptomatic CMI has a risk of acute exacerbation without timely revascularization.Case presentationA 54-year-old man who had had postprandial pain for 6 months was admitted to our hospital because of vomiting and diarrhea. Although the celiac and superior mesenteric arteries were occluded at the proximal portion, contrast enhancement of the bowel wall was good in contrast-enhanced computed tomography (CECT). Endoscopic examination revealed only a healed gastric ulcer and slight mucosal erosions in the colon. He was diagnosed as having acute enteritis or inflammatory digestive disease and observed with conservative therapy, which improved his acute symptoms. On hospitalization day 42, he suddenly complained of lower back pain. CECT showed abdominal free air, which indicated gastrointestinal perforation. Emergency surgery was performed for jejunum resection. Two days later, a second operation was performed for a leak in the anastomotic site of the jejunum. Necrotic change in the small intestinal serosa was also observed and required broad resection of the small intestine. He was diagnosed with acute exacerbation of CMI, and we performed surgical retrograde bypass to the gastroduodenal artery using a saphenous vein graft as the third operation. After the surgery, he was free from digestive symptoms and was discharged.ConclusionsWhen patients complain of chronic and gradual digestive symptoms, we should always consider symptomatic CMI. Timely mesenteric revascularization is important for symptomatic CMI before severe complications occur.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
