Although some mesenchymal lesions include readily diagnosable entities, some patients have difficult presentations and unusual radiographic results. This review of mesenchymal tumors covers hemangioma, infantile hemangioendothelioma, angiomyolipoma, angiosarcoma, epitheloid hemangioendothelioma, fibroma, malignant fibrous histiocytoma, inflammatory pseudotumor, mesenchymal hamartoma, embryonal sarcoma, and sarcomatoid hepatocellular carcinoma.
