BACKGROUND AND STUDY AIMS:  The relevance of incidental colorectal focal (18) F-FDG PET/CT uptake is debatable. All patients who were referred for colonoscopy because of incidental colonic focal FDG uptake were included in this retrospective study. PATIENTS AND METHODS:  PET/CT imaging characteristics were reviewed by a nuclear physician who was blinded to endoscopic and histopathological findings to determine the location of FDG uptake sites and to measure the maximum standardized uptake values (SUVmax) and metabolic volume (MV)...

OBJECTIVE: We attempted to develop a scoring system for facilitating decision making regarding the performance of emergency endoscopy in patients with colonic diverticular hemorrhage. METHODS: This study involved analysis of the data of 178 patients who presented with hematochezia and were diagnosed as having colonic diverticular hemorrhage by colonoscopy. The patients were divided into 2 groups depending on whether the bleeding source was identified or not at the initial endoscopy (source-identified and source-not-identified groups), and on the basis of the results obtained, we established a scoring system for predicting successful identification of the bleeding source...

BACKGROUND: Neuroendocrine tumors (NETs) are heterogeneous neoplasms that originate from cells with a secretory function. Small bowel NETs (SB-NETs) are related to serotonin hypersecretion which causes: flushing, diarrhea, abdominal pain, bronchoconstriction and heart involvement, also known as carcinoid syndrome (CS). CS can be confused with an allergic reaction and thus should be considered as a differential diagnosis in the allergy consult. We present the case of a pediatric patient initially referred under the suspicion of food allergies...

We report a case of a 48-year-old female patient, who presented with abdominal pain, jaundice, and lack of appetite. Ultrasound showed intrahepatic biliary dilatation with retroperitoneal lymphadenopathy. Further magnetic resonance cholangiopancreatography detected Klatskin tumor. Computed tomography (CT) confirmed the Klatskin tumor with liver metastases and retroperitoneal lymphadenopathy. Biopsy from the hepatic lesion identified mucinous adenocarcinoma, likely originating from bile ducts. Endoscopic retrograde cholangiopancreatography was performed 3 times with stents placed in the left and right hepatic bile ducts...

A 27-year-old female heroin addict presented with a peritonitic and distended abdomen. Her medical history included depression and a 3-year history of heroin abuse with attendant constipation. CT scan showed free intraperitoneal gas, massive faecal distension of the rectum and sigmoid colon and likely bowel necrosis. She underwent an emergency Hartmann's procedure for perforation of the sigmoid colon. Pathology identified two areas of stercoral ulceration, one of them being the area of perforation. Postoperatively, the patient developed a deep vein thrombosis and is now on anticoagulant therapy...
