Hemobilia and occult cystic artery stump bleeding after a laparoscopic cholecystectomy: endovascular treatment with N-butyl cyanoacrylate.

Hemobilia is a rare phenomenon. In this case report we present an emergent transcatheter glue embolization (in which N-butyl cyanoacrylate is used as an embolizing agent) due to arteriobilary fistula occurred following the laparoscopic cholecystectomy in a 41-year-old woman.

Segmental costovertebral anomaly presenting with horn-like appearance in the chest.

Several types of abnormalities of the ribs have been reported. Many of these anomalies usually result in the correct diagnosis thanks to the characteristic radiological appearances. But some of the anomalies are rare and it is important to recognize and get accustomed to differing appearances of these osseous abnormalities in order to differentiate the pathological processes and to diagnose the syndromes which may accompany rib anomalies.

Bilateral extra-adrenal perirenal myelolipomas: CT features.

Myelolipomas are rare benign tumours composed of adipose tissue and haematopoietic cells that are typically found in adrenal glands but have also appeared in extra-adrenal sites. Distinguishing between extra-adrenal myelolipomas and malignant tumours, such as liposarcomas, is crucial to avoid an invasive procedure. To this end, we present a comprehensive report of the CT imaging characteristics of a pathologically proven bilateral extra-adrenal perirenal myelolipoma.

Incidental pancreatic lipomas: computed tomography imaging findings with emphasis on diagnostic challenges.

Purpose: The purpose of this study was to describe the computed tomography (CT) findings of pancreatic lipomas of 9 cases, with emphasis to diagnostic challenges.

Methods: Between March 2006 and April 2008, 9 patients with pancreatic lipomas that were diagnosed by CT were reviewed in the present study. Clinical data and CT features of these 9 cases were retrospectively analysed.

Prevalence and MDCT characteristics of asymptomatic Bochdalek hernia in adult population.

Purpose: To determine the frequency of asymptomatic incidental Bochdalek hernias in adults, using multidetector computed tomography (MDCT), and to ascertain any possible relationship between Bochdalek hernia and age, gender, or body mass index (BMI).

Materials And Methods: Seven hundred and forty-eight abdominal, and 602 chest MDCT scans, which had been performed for a variety of reasons on 1350 adults, were investigated retrospectively. Location and size of Bochdalek hernias seen on these scans were correlated with age, gender, and BMI.

Digital subtraction angiography of a persistent trigeminal artery variant.

Persistent trigeminal artery variants are described as cerebellar arteries that directly originate from the precavernous segment of the internal carotid artery. This has been observed in 0.18% of cerebral catheter angiograms.

CT-angiographic demonstration of hepatic collateral pathways due to superior vena cava obstruction in Behçet disease.

Behçet disease (BD) is a chronic multisystemic inflammatory disorder, mainly characterized by recurrent oral and genital ulcers, skin lesions, and uveitis. Large vein thrombosis in BD is unusual; when present, it is most frequently seen in the inferior or superior vena cava (SVC). The authors describe an unusual hepatic pseudolesion caused by abnormal focal enhancement through collateral pathways to the liver in two BD patients with SVC occlusion on three-dimensional multi-detector computed tomography, using volume rendering and maximum intensity projection techniques.

Dural sinus vein thrombosis in a patient with colon cancer treated with FOLFIRI/bevacizumab.

The adverse effects of regimes in cancer treatment have forced us to change to new targeted therapy options. Understanding these side effects, which can lead to discontinuation of the new therapy strategies, will allow the clinical management of these side effects and result in continuing therapies with effective medications. Bevacizumab, which is an IgG1 antibody against vascular endothelial growth factor, has side effects such as proteinuria, hypertension, venous and arterial thromboembolic events, and hemorrhage.

Synchronous tonsil, gallbladder, and cardiac metastases without any other visceral metastases of malignant melanoma.

Background: Malignant melanoma is a highly unpredictable tumor that has capacity to metastasize to any organ. A better understanding is needed of the clinicopathologic features of metastatic melanoma and, in particular, of its rare manifestations.

Case Report: A 33-year-old woman with a past medical history of malignant melanoma presented with symptoms of throat discomfort and bleeding.

Computed tomographic and magnetic resonance imaging findings of asymptomatic intra-abdominal gastrointestinal system lipomas.

Lipomas are common benign mesenchymal neoplasms documented in literature. This study aimed to describe the computed tomographic (CT) and magnetic resonance imaging (MRI) findings of gastrointestinal system lipomas, all of which are incidentally found in routine abdominal imaging studies. Lipomas were depicted as homogeneous, nonenhancing, well-marginated lesions consistent with adipose tissue on CT and MRI.
