The American College of Radiology Pediatric LI-RADS Working Group was formed in 2017 with the task of advancing the imaging work up, diagnosis, and management of pediatric liver tumors, particularly pediatric hepatic malignancies. This exhibit will present how the Pediatric LI-RADS Working Group is working towards this goal by means of advocacy, education, and research. In regard to advocacy, the Working Group is a strong proponent for the standardization of imaging practice for pediatric liver tumors. Based on expert interpretation of the literature, the Working Group established consensus imaging recommendations for children with a known or suspected liver neoplasm. This exhibit will highlight the key recommendations for choosing imaging modality and protocol for the work up of a pediatric liver tumor. Education is another major component of the Working Group’s mission. The group has presented at meetings and published manuscripts on various topics. Topics include age and indication-based imaging strategies for pediatric liver tumors and liver masses in children with predisposition syndromes. This exhibit will touch on the major teaching points of these papers. Lastly, this exhibit will present the research conducted by the Pediatric LI-RADS Working Group. Their research studied the utility of applying adult LI-RADS criteria to children. Another study analyzed the imaging features of hepatocellular carcinoma in children with and without an underlying predisposition. To summarize, through discussion of the major accomplishments of the Pediatric LI-RADS Working Group, this exhibit will provide insight, education, and resources for the radiologist interpreting pediatric liver tumors.

Keywords: Liver Tumor, Malignancy, Abdominal Imaging

Teaching Points: 1. Review the imaging approach and differential diagnosis for cardiac masses in children 2. Illustrate the characteristic imaging findings of benign and malignant pediatric cardiac tumors and understand the spectrum of pseudotumors that may be encountered in pediatric cardiac disease. 3. Discuss the screening guidelines and management approach to cardiac masses in children with predisposition syndromes. 4. Review radiologic-pathologic correlation for cardiac masses and pseudomasses in children. Outline: 1. Review our institutional experience, including the relative frequency of cardiac masses and pseudomasses 2. Describe the recommended imaging protocols for screening, surveillance, and characterization of cardiac masses on echocardiography, CT, and MRI 3. Describe the imaging findings at echocardiography, CT, and MRI in the spectrum of pediatric cardiac tumors and pseudotumors in: a. Predisposition syndromes: Tuberous sclerosis, Nevoid basal cell carcinoma syndrome, Carney complex, etc. b. Primary malignant cardiac tumors: Rhabdomyosarcoma, angiosarcoma, malignant fibrous histiocytoma, fibrosarcoma, etc. c. Secondary cardiac tumors: Osteosarcoma, hepatoblastoma, neuroblastoma, Ewing sarcoma, synovial cell sarcoma, etc. d. Benign cardiac masses: Mature teratoma, vascular malformations, lipoma, myxoma, fibroma, etc. e. Cardiac pseudomasses and mimics: Thrombus, Epicardial/myocardial fat necrosis, pseudoaneurysms, granulomatous disease, etc. 4. Provide radiologic-pathologic correlation for cardiac masses and pseudomasses in children Read More

Children undergoing hematopoietic stem cell transplantation (HSCT) are at high risk for infectious and non-infectious complications after transplant. While computed tomography (CT) is commonly used to identify asymptomatic infections or other abnormalities before transplant, there are limited data to support routine pre-transplant imaging with CT. We aimed to investigate the frequency of CT findings of infection, air trapping, or other unexpected abnormalities pre-HSCT. Read More
