    ABSTRACT: Cholecystenteric fistula is one of the rarest complications of biliary lithiasis, with a frequency of less than 1%. Bouveret syndrome is a gastric outlet obstruction produced by gallstone(s) located in the distal stomach or proximal duodenum. The route of gallstone migration to the bowel is most commonly via a cholecystoduodenal fistula; however, fistulization of the stomach is a rarer variation. Early diagnosis of this situation is crucial to reduce morbidity and mortality. In this report, we present a patient with cholecystogastric fistula and Bouveret syndrome. To our knowledge, there is no published paper in the literature related to the diagnosis of Bouveret syndrome with multidetector computed tomography (MDCT) (64 detectors) and/or contrast-enhanced magnetic resonance cholangiopancreatography (CE-MRCP). Our aim was to discuss the efficacy of MDCT and CE-MRCP in the detection and evaluation of cholecystenteric fistulas. We showed the exact localization and relation of biliary stones and the fistula by MDCT and CE-MRCP. We also evaluated the biliary system with CE-MRCP physiologically. In conclusion, when biliary lithiasis and ileus are detected in plain radiography, the first-line diagnostic tool should be MDCT. In complicated cases or when biliary obstruction is suspected, CE-MRCP can give important morphological and physiological information regarding the whole abdomen and biliary system.

    ABSTRACT: Subhepatic-retrocecal appendicitis is a rare entity in which the diagnosis is challenging. In patients presenting with right abdominal pain with atypical clinical, laboratory and ultrasound (US) findings, acute appendicitis should be eliminated with computed tomography (CT). Multi-detector CT (MDCT) can be used effectively for the diagnosis of retrocecal appendicitis without additional preparation or focused examination. Here, we present a patient with acute subhepatic-retrocecal appendicitis in whom the clinical and US findings mimicked acute cholecystitis. To the best of our knowledge, there is no previous report related to acute appendicitis presented only with pericholecystic fluid that could be diagnosed with MDCT. Retrocecal-subhepatic appendicitis is a rare condition that might present with atypical clinical, laboratory and radiological signs. US is usually insufficient for the definitive diagnosis. In this situation, MDCT could be a rapid and efficient tool for localizing the appendix and for the differential diagnosis.

    ABSTRACT: Obscure gastrointestinal bleeding (OGB) is defined as bleeding of an unknown origin that persists or recurs after negative initial endoscopies (1). Capsule endoscopy (CE) has been recommended as the third diagnostic test for patients with OGB (2). The etiological causes of small intestinal bleeding are tumors, Meckel's diverticulum, Crohn's disease, vascular lesions, and nonsteroidal antiinflammatory drug-induced small bowel disease (3). Ureteroenteric fistula is known to be a rare cause of OGB. A 38-year-old female had undergone surgery for cervical carcinoma in August 2009. A ureteral injury had developed as a complication during the procedure and was repaired intraoperatively. Thereafter, in December 2010, ureteroplasty and double-J stent insertion were performed for ureteral stricture. In the postoperative period, during the follow-up for surgical wounds and double-J stent, a urinary tract infection was detected. As she was treated for this infection, she developed hematochezia accompanied by a concurrent hematuria. No lesion could be found on the lower and upper gastrointestinal (GI) endoscopies. Subsequently, she referred to our clinic for further investigation. On CE, a lesion compatible with ureteroenteric fistula was observed at the distal small intestine (Figure 1). Magnetic resonance (MR) enterography revealed that the double-J stent was displaced and there was a fistula between the ureter and ileum (Figure 2 A, B, C). Ureteroenteric fistula is a rare cause of GI hemorrhage of unknown etiology. To our knowledge, this is first case of CE appearance of the ureteroenteric fistula.

    ABSTRACT: PURPOSE: We aimed to present our clinical experience with the renal artery catheterization (RAC) technique, which reduces the volume of intra-arterial contrast media (ICM) used during endovascular aortic repair (EVAR), and describe the short term results of this technique. MATERIALS AND METHODS: We retrospectively evaluated 16 patients (15 males and one female) who underwent EVAR between March 2011 and February 2012 using the RAC technique for an abdominal aortic aneurysm. A Simmons-1 catheter was preferred for renal artery cannulation. The mean age of the patients at the time of treatment was 70 years (range, 61-82 years). Fifteen cases were fusiform aneurysms, and one case was a saccular aneurysm. Creatinine and estimated glomerular filtration rate (eGFR) values were recorded before the procedure and during the first 72 hours post-procedure. RESULTS: Bifurcated stent grafts were implanted with 100% procedural success using the RAC technique. The inferiorly positioned renal artery was cannulated with a Simmons-1 catheter in the first five patients, and was maintained at the level of the renal artery orifice in the remaining patients. The mean volume of the ICM used was 47 mL (range, 23-83 mL). The creatinine and eGFR values were not significantly different between the pre- and postoperative periods (P > 0.05). CONCLUSION: Reducing the volume of ICM used during EVAR is critical for protecting renal function. The RAC technique is a safe and effective method in appropriate patients when performed by experienced clinicians.

    ABSTRACT: A radiological sign can sometimes resemble a particular object or pattern and is often highly suggestive of a group of similar pathologies. Awareness of such similarities can shorten the differential diagnosis list. Many such signs have been described for X-ray and computed tomography (CT) images. In this article, we present the most frequently encountered plain film and CT signs in chest imaging. These signs include for plain films the air bronchogram sign, silhouette sign, deep sulcus sign, Continuous diaphragm sign, air crescent ("meniscus") sign, Golden S sign, cervicothoracic sign, Luftsichel sign, scimitar sign, doughnut sign, Hampton hump sign, Westermark sign, and juxtaphrenic peak sign, and for CT the gloved finger sign, CT halo sign, signet ring sign, comet tail sign, CT angiogram sign, crazy paving pattern, tree-in-bud sign, feeding vessel sign, split pleura sign, and reversed halo sign.
