Computed tomography and angiogram of primary hepatic rhabdomyosarcoma: report of two adult cases.

Two adult cases of primary hepatic rhabdomyosarcoma, one of which was associated with hepatocellular carcinoma and had double malignant tumors, are described with emphasis on the radiologic features. On precontrast computed tomography, the lesion appeared as a well-defined hypodense mass like an abscess, while linear mottled enhancement was observed on the postcontrast scan. Angiography revealed displacement of the hepatic arteries and portal veins, irregular neovascularity in the peripheral portion, and scant tumor stain without dilatation of the feeding artery. Review of the literature revealed only 10 previous reports.
