Liver adenomas in glycogen storage disease in children. Ultrasound and angiographic study

The authors report the ultrasound and angiographic features of adenomas occurring in children with glycogen storage disease. Seven cases from 83 patients were diagnosed either by ultrasound, preoperative angiography or during surgery. The lesions appear on ultrasound as multiple rounded intrahepatic masses. Their degree of echogenicity as well of vascularity on angiography is highly variable. Ultrasound is the modality of choice in detecting adenomas. No malignant degeneration was observed.
