This article describes, illustrates, and correlates imaging and pathologic features of primary vascular mesenchymal neoplasms of the liver, which arise from the vascular endothelium and perivascular epithelioid cells.
Familiarity with the spectrum of benign, malignant-potential and malignant vascular neoplasms, and nonneoplastic mimickers allows consideration in the differential diagnosis of enhancing hepatic masses. Understanding relevant pathologic features facilitates recognition of key imaging features, specifically dynamic contrast enhancement patterns on CT and MRI, which provide a useful classification system.
本文描述、阐述并关联了肝原发性血管间叶性肿瘤的影像学和病理学特征，这些肿瘤来源于血管内皮和血管周上皮样细胞。
熟悉良性、恶性潜能和恶性血管性肿瘤以及非肿瘤性类似物的范围，可以帮助我们对增强型肝肿块进行鉴别诊断。了解相关的病理学特征有助于识别关键的影像学特征，特别是 CT 和 MRI 上的动态对比增强模式，这提供了一个有用的分类系统。
