Hepatic pathology after Fontan palliation: spectrum of imaging findings.
Patients with congenital heart disease corrected by Fontan palliation have chronic liver congestion that commonly progresses to fibrosis and cirrhosis with resultant complications. ⋯ A high percentage of patients had imaging abnormalities of the liver, chiefly abnormal parenchymal enhancement, which became more apparent as the duration of the Fontan circulation increased. The hypervascular nodules sometimes present had imaging characteristics most closely resembling those of focal nodular hyperplasia. The underlying fibrosis and eventual development of cirrhosis raise the risk of developing hepatocellular carcinoma.

Few published series are dedicated solely to CT-guided vertebral bone biopsy in children. ⋯ Percutaneous CT-guided vertebral bone biopsy can be performed safely in children with a high degree of diagnostic accuracy.

Historically, the evaluation of the pediatric chest has been accomplished via CT and conventional radiography. Our objective is to discuss and illustrate the role of US as a non-ionizing radiation alternative in the evaluation of the pediatric chest. US is a valuable tool in the evaluation of the pediatric chest. It can be used as a first-line modality in the evaluation of superficial lumps and bumps of the chest wall, diaphragmatic motion, the thymus and pleural effusions, and it can play a valuable secondary role in evaluation of mediastinal masses and pulmonary parenchymal disease.
