Why the study?
Diagnosing rare mesenchymal malignant liver lesions is challenging due to their rarity and typically requires histological confirmation.
Ultrasound, including color Doppler and contrast-enhanced ultrasound, can help focus the differential diagnosis of rare malignant mesenchymal liver lesions.
May refine differentials for rare liver lesions on ultrasound; leaves open prospective validation studies.
The diagnosis or rare mesenchymal malignant lesions of the liver may be a challenge owing to the rarity of the disease and is usually made by histological confirmation. An ultrasound examination with, if required, color Doppler sonography and contrast-enhanced ultrasound, taking into account the clinical background of the patient, may help to focus the differential diagnosis. In this review, we describe the pathological and ultrasound features of several rare mesenchymal malignant liver lesions which include undifferentiated sarcoma of the liver, leiomyosarcoma, angiosarcoma, fibrosarcoma, liposarcoma, and epithelioid hemangioendothelioma.
