Imaging review of spontaneous renal hemorrhage.

Spontaneous renal hemorrhage (SRH) is a diagnostic challenge and a significant cause of morbidity, and sometimes mortality. Early identification is essential to institute lifesaving and reno-protective interventions. In this review, we classify spontaneous renal hemorrhage by location, presentation and etiology.

Phase 2 study of pembrolizumab and circulating biomarkers to predict anticancer response in advanced, unresectable hepatocellular carcinoma.

Background: Checkpoint inhibitors have shown modest activity in patients with advanced hepatocellular carcinoma (HCC). Herein, the authors report a prospective single-institution clinical/translational phase 2 study of pembrolizumab in patients with advanced HCC and circulating biomarkers closely related to response.

Methods: Pembrolizumab was administered at a dose of 200 mg intravenously every 3 weeks among patients who may have developed disease progression while receiving, were intolerant of, or refused sorafenib.

Imaging of Unusual Renal Tumors.

Purpose Of Review: Renal masses are a wide entity and a common finding in clinical practice. Detection of these masses has increased in the last years, yet mortality rates have slightly decreased.

Recent Findings: According to the World Health Organization classification, there are 8 types, 51 subtypes, and a lot more subsequent subclassifications of renal tumors.

A Comprehensive Approach to Hepatic Vascular Disease.

The liver has a complex vascular supply, which involves the inflow of oxygenated blood through the hepatic artery (systemic circulation) and deoxygenated blood through the portal vein (portal circulation), as well as the outflow of deoxygenated blood through the hepatic veins to the inferior vena cava. A spectrum of vascular variants can involve the liver. Some of these variants may result in areas of enhancement that can mimic more serious pathologic conditions.

Recurrent Cardiac Tamponade: An Unusual Presentation of Intrahepatic Cholangiocarcinoma.

A 48-year-old Egyptian woman presented with 8 months of sharp right upper chest pain and weight loss. She was discovered to have an enlarged cardiac silhouette on chest x-ray, and an echocardiogram revealed a large pericardial effusion with diastolic right atrial collapse. Pericardial window was done, and epithelial membrane antigen-positive neoplastic cells were identified in the pericardial fluid.

Two Rare Cases of Hepatocellular Carcinoma after Kasai Procedure for Biliary Atresia: A Recommendation for Close Follow-Up.

The instigation of the Kasai procedure in infants who are born with biliary atresia has led to increased survival in this population for over half a century. The many complications that arise as a result of biliary atresia led to an early death for most patients. However, the Kasai procedure is not without its own impediments.

Imaging evaluation of the inferior vena cava.

The inferior vena cava (IVC) is an essential but often overlooked structure at abdominal imaging. It is associated with a wide variety of congenital and pathologic processes and can be a source of vital information for referring clinicians. Initial evaluation of the IVC is most likely to occur at computed tomography performed for another indication.

Focal nodular hyperplasia within accessory liver: imaging findings at computed tomography and magnetic resonance imaging.

Accessory liver tissue is a rare but probably underreported entity that may harbor the same spectrum of pathology as that of the parent organ. The rarity and aberrant locations of such lesions cause confusion and may lower diagnostic confidence despite otherwise classic radiographic appearances. Focal nodular hyperplasia (FNH) is the most common non-hemangiomatous benign hepatic tumor, but to our knowledge, ectopic FNH has been reported only once before in the gastroenterology literature.

A case of a ruptured sclerosing liver hemangioma.

Hemangiomas are the most common benign tumors found in the liver, typically asymptomatic, solitary, and incidentally discovered. Although vascular in nature, they rarely bleed. We report a case of a 52-year-old woman with a previously stable hemangioma who presented to our hospital with signs and symptoms indicative of spontaneous rupture.

Liver transplantation for hepatocellular carcinoma in the model for end-stage liver disease era.

Background: Since March 2002, the United Network for Organ Sharing liver allocation policy has given extra priority to patients with hepatocellular carcinoma (HCC) who meet specific medical criteria. This study reviews our experience with liver transplantation for HCC under this system.

Study Design: Between March 2002 and April 2009, 244 patients with HCC underwent primary liver or liver-kidney transplantation under the current allocation system at the University of Miami.

Innominate artery occlusive disease: sonographic findings.

Objective: The objective of this study was to report the sonographic abnormalities in a group of patients with angiographically proven innominate artery stenosis and occlusion.

Materials And Methods: A review of all cerebrovascular sonograms at our institutions was undertaken to identify patients with complete or partial flow reversal in the right vertebral artery and reversal or midsystolic deceleration of flow in any one of the three major segments of the right carotid system (common, internal, or external carotid artery). The distribution and appearance of these abnormalities was evaluated, and the presence or absence of tardus-parvus waveforms was noted in any segment of the right carotid artery.

Complications of renal transplantation.

Continued improvements in graft survival have led to widespread acceptance of renal transplantation as the preferred treatment for the majority of patients with end-stage renal disease. The long-term care of these patients is often provided away from transplantation centers. This article presents both the clinical and imaging features of renal transplantation complications and their interventional management.

CT features of renal infarction.

Purpose: To demonstrate the different patterns of renal infarction to avoid pitfalls. To present 'flip-flop enhancement' pattern in renal infarction.

Materials And Methods: Retrospective review of a total of 41 renal infarction in 37 patients were done.

Uterine artery embolization: sonographic imaging findings.

Objective: To examine the sonographic and angiographic imaging findings before and after uterine fibroid embolization for symptomatic leiomyoma.

Methods: This prospective study involved 14 premenopausal women who underwent uterine fibroid embolization for symptomatic leiomyoma. Preprocedure sonography with color Doppler imaging was performed.
