PURPOSE: Contrast-enhanced ultrasound can differentiate malignant from benign hepatic tumors, but has not been studied in malignant mesenchymal liver tumors. METHODS: We describe the findings of contrast-enhanced ultrasound in a cohort of five patients with histological-proven malignant hepatic mesenchymal tumors. RESULTS: The presence of imaging features such as peripheral (nodular) enhancement, chaotic central vascularization, and absence of contrast enhancement in the late phase allowed differentiation from hemangiomas. CONCLUSIONS: If these findings are demonstrated in large hepatic tumors, then the diagnosis of hemangioma is unlikely and further workup is necessary.
