A Case of Chronic Mesenteric Ischemia imitating Crohn's disease

Objectives: We present an atypical case of chronic mesenteric ischemia with weight loss as only clinical manifestation and endoscopic findings imitating Crohn´s disease. Materials and Methods: A CT Angiography of abdomen confirmed the diagnosis of mesenteric ischemia after total occlusion of celiac trunk and superior mesenteric artery. Results: The patient died due to severe sepsis, as a result of extended bowel infarction. Conclusions: The diagnosis of chronic mesenteric ischemia requires a high degree of clinical suspicion and can be life-saving if early conducted.

A Case of Mesenteric Pseudocyst Causing a Massive Abdominal Swelling

We present the case of a 55-year-old man, with a self-limited febrile condition associated to polyserositis with inconclusive investigation. Bilateral pleural and pericardial effusions resolved. The peritoneal fluid loculated and was compatible with an exudate. The patient remained clinically asymptomatic. Two years later, examination revealed a palpable and painless abdominal mass, which imaging study suggested a cystic lesion. Surgical resection was performed and the histological examination revealed a mesenteric pseudocyst. Mesenteric pseudocysts are rare intra-abdominal cystic masses, mostly benign, without causing specific symptoms. Although imaging tests are useful for their differential diagnosis, the histology is mandatory.

A Young Woman with Fever and Cervical Lymphadenopathy

Kikuchi-Fujimoto's disease is a self-limiting and rare disorder of unknown aetiology. The typical presentation includes fever, cervical lymphadenopathy and night sweats. Consequently, it is part of the differential diagnosis of infectious, lymphoproliferative and connective tissue diseases. Histology demonstrates necrotizing histiocytic lymphadenitis. Treatment is symptomatic with non-steroidal antiinflammatory agents, although there are reports of corticosteroid use in complicated cases. We present the case of a 23-year-old woman admitted to hospital for fever and cervical lymphadenopathies, and diagnosed with Kikuchi-Fujimoto's disease.
