Aneurysmal bone cysts (ABCs) are expansile lytic lesions and can cause significant disability and pain most commonly seen in patients 10-30 years old. This study evaluates the technical feasibility, safety, and efficacy of percutaneous management of ABCs in pediatric and adolescent patients. Read More

The role of locoregional therapy options (percutaneous thermal ablation, chemoembolization, and/or radioembolization) continues to gain traction in the pediatric oncology world, particularly with the management of primary and metastatic liver lesions. Post-treatment imaging of the liver must clearly differentiate between treatment response, residual untreated disease and progressive disease in order to guide the future therapeutic options. The post-treatment imaging appearance of pediatric liver lesions can be affected by multiple factors (tumor type, tumor vascularity, radiation vs non-radiation therapy, background liver characteristics, time lapse from the interventional oncology procedure, imaging technique, e.g.). The understanding and interpretation of such factors continues to evolve, as seen with the most recent ACR LI-RADS Treatment Response Assessment Update in 2024. This case cohort presents illustrative examples from multiple pediatric interventional oncology programs, using various imaging modalities to demonstrate post-treatment liver imaging findings following locoregional therapy for both primary and metastatic liver lesions in pediatric patients.

Evolution of MR Lymphangiography has expedited diagnosis and advanced potential implications for treatment in lymphatic disorders. In particular, evaluation of the central conducting lymphatic channels with dynamic contrast enhanced MR provides better spatial resolution, while sparing ionizing radiation inherent in lymphangio-scintigraphy and catheter lymphangiography. We will review indications, technique with pearls and pitfalls, and overall success rates after MR lymphangiography at our institution. To discuss post-imaging clinical outcomes and implications for treatment. To illustrate imaging findings of various lymphatic pathology diagnosed on MR. Read More
