Benign Hepatic Nodules Mimicking Hepatocellular Carcinoma in the Setting of Fontan-associated Liver Disease: A Case Report.

Unlabelled: Fontan procedure, in which systemic circulation is redirected into pulmonary circulation by a baffle, is a palliative surgical strategy for patients born with single ventricle congenital heart disease. Hemodynamic changes secondary to Fontan procedure, also termed as Fontan physiology, result in end-organ damage, especially of the liver. Fontan-associated liver disease (FALD) represents a spectrum of pathologies ranging from mild liver fibrosis to advanced liver cirrhosis and hepatocellular carcinoma (HCC).

Retroperitoneal and Pelvic Lymph Nodes in Children: What Is Normal?

The purpose of this study was to evaluate size criteria for retroperitoneal and pelvic lymph nodes in healthy children. We identified all trauma patients younger than 18 years old without underlying disease and with CT scans without abnormalities in the abdomen and pelvis during 2014-2015. Two pediatric radiologists reviewed the studies independently and recorded the number of retroperitoneal and pelvic lymph nodes with a long diameter 5 mm or greater and the size (two perpendicular diameters) of the largest lymph node in five anatomic locations.

Characteristics of testicular tumors in prepubertal children (age 5-12 years).

Introduction: Testicular tumors in children have two peaks with different types of tumors; in the first 4 years of life a third to half are benign with increased risk of malignancy during puberty. The pathology of testicular tumors between these peaks, at the age of 5-12 years, is not known. We hypothesized that because of the low level of testosterone at this time, the incidence of malignant tumors is very low.

Fishtail deformity of the distal humerus: association with osteochondritis dissecans of the capitellum.

Background: Fishtail deformity is a rare deformity of the humerus exhibiting concavity of the lateral trochlea, resulting in ulnotrochlear joint derangement. We wanted to share our experience that osteochondritis dissecans of the capitellum is a common associated complication.

Objective: To summarize imaging of fishtail deformity in children centered on complications of the radiocapitellar joint.

Reirradiation of Recurrent and Second Primary Head and Neck Cancer With Proton Therapy.

Purpose: To report the clinical outcomes of head and neck reirradiation with proton therapy.

Methods And Materials: From 2004 to 2014, 61 patients received curative-intent proton reirradiation, primarily for disease involving skull base structures, at a median of 23 months from the most recent previous course of radiation. Most had squamous cell (52.
