Hepatocellular carcinoma is a common malignancy in this locality due to the high prevalence of hepatitis B carriers. Radiofrequency ablation is frequently used for treatment of hepatocellular carcinoma. Thermal injury to the diaphragm during radiofrequency ablation for liver tumour is a rare complication. Thermal injury may lead to a defect in the diaphragm and hernia formation. Intestinal obstruction can result from incarceration of the diaphragmatic hernia. We present a patient with intestinal obstruction due to incarcerated diaphragmatic hernia after radiofrequency ablation. The causes, presentation, and imaging findings of this condition are reviewed.
