RESUMEN
Pancreatic arteriovenous malformation (PAVM) is very rare anomaly. It occurs most commonly in the pancreatic head portion and gastrointestinal bleeding is the most common symptom. The management of PAVM is rather complex, with complete treatment usually accomplished by a total extirpation of the affected organ or at least its involved portion. We report the clinical presentation and management of 64 year-old male patient with PAVM, which was developed in pancreatic tail portion with sudden abdominal pain. Pancreatic computed tomography and magnetic resonance cholangiopancreatography were consistent with a vascular formation on pancreatic tail portion and simultaneously revealed with pseudocysts beside it. A subsequent superior mesenteric artery angiographic findings depicted PAVM on pancreatic tail portion. The patient underwent laparoscopic distal pancreatectomy and splenectomy and had a favorable outcome.

Pseudomembranous colitis is mostly related to antibiotics and it presents symptoms of diarrhea, abdominal pain, fever, hypoalbuminemia and hypovolemia. Diarrhea is the most common manifestation, but in geriatric patients, symptoms of pseudomembranous colitis can be different from those of usual cases and the course of disease can be more aggressive. For these reasons, it can be misdiagnosed. So physicians must take pseudomembranous colitis into consideration in older patients with acute abdominal pain, who have been treated with antibiotics. We reported a case of an older patient with pseudomembranous colitis which was misdiagnosed as acute appendicitis with perforation.
