The aim of this study was to determine the accuracy of multidetector row CT angiography in the diagnosis of acute mesenteric ischemia. Ninety-three consecutive studies on 91 patients with clinically suspected acute mesenteric ischemia underwent abdominal CT angiography as the first, and usually the sole, diagnostic procedure. CT was performed with a multidetector 16-row CT system from the level of the diaphragm to the pelvis in two phases: early arterial and late portal phase. CT examinations were reviewed by the duty radiologist. Final diagnosis was established by a senior radiologist. CTA was diagnostic in 92 studies. Mesenteric ischemia was diagnosed in 18 patients, 14 of them were of the thromboembolic type and four from the nonocclusive type. Positive CTA findings were confirmed by surgery in 13 patients and by clinical follow-up in three cases. Other reasons for abdominal pain were diagnosed by CT in 38 patients out of the remaining 74. There were two false positive and two false negative CT results, resulting in an overall accuracy of 95.6%. Multidetector CT angiography is a fast and accurate investigation for the diagnosis of acute mesenteric ischemia and in most cases can be used as the sole diagnostic procedure.

Conservative treatment and delayed operation is an acceptable option for acute cholecystitis. Percutaneous gall bladder aspiration is a simple and effective procedure, with a high success rate and low morbidity. Laparoscopic cholecystectomy after drainage of the gall bladder has low morbidity with a relatively low conversion rate.

Intra luminal gallbladder bleeding is a rare cause of hemobilia that results in upper gastro-intestinal bleeding. In this case report we present a patient who presented with melena and eventually was diagnosed as bleeding from an ulcer in the gallbladder which was induced by gallstones and eroded into the cystic artery. Surgery revealed perforation of gallbladder which was the result of a pressure sore induced by a second gallstone.

Introduction:Usual treatment for patients with aldosteroneproducing adrenal adenoma is adrenalectomy, whereas adrenal hyperplasia is generally treated medically. Selective adrenal venous sampling (AVS) has been adopted to differentiate between adenoma and hyperplasia. A previous ratio used in our institution for the diagnosis of adenoma proved to be too low. As a result, a disproportionate number of patients with a preoperative diagnosis of adenoma were operated and subsequently found to have hyperplasia.
