Contrast-enhanced ultrasound can differentiate malignant from benign hepatic tumors, but has not been studied in malignant mesenchymal liver tumors.
We describe the findings of contrast-enhanced ultrasound in a cohort of five patients with histological-proven malignant hepatic mesenchymal tumors.
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.
If these findings are demonstrated in large hepatic tumors, then the diagnosis of hemangioma is unlikely and further workup is necessary.
超声造影可区分肝脏良恶性肿瘤，但尚未在肝脏恶性间叶性肿瘤中进行研究。
我们描述了5例经组织学证实的肝脏恶性间叶性肿瘤患者的超声造影表现。
外周（结节状）强化、中央血管紊乱及延迟期无造影剂强化等影像学特征有助于与肝血管瘤相鉴别。
如果在肝脏较大肿瘤中出现这些表现，则肝血管瘤的诊断可能性不大，需要进一步检查。
