CTICasesDiaphragmatic Defect post-Tumor Ablation
Imaging findings
CT abdomen shows fat stranding and a small, focal defect in the right hemidiaphragm directly adjacent to a previously ablated liver dome tumor.
Key takeaways
Thermal ablation (radiofrequency or microwave) of hepatic tumors located near the diaphragm can cause collateral thermal injury. This can lead to localized diaphragmatic necrosis and defect formation, which carries a risk of diaphragmatic hernia.
