摘要：
不连续的周边强化是一种通常归因于典型海绵状血管瘤的强化模式，这是肝脏最常见的良性实性病变。然而，在许多其他良性和恶性局灶性肝脏病变中，可能会遇到不连续的外周强化，作为非典型表现或演变，并且肝动脉期不连续外周过度强化的血管瘤可能并不总是在门静脉和门脉上具有典型的造影后模式。延迟阶段。因此，腹部放射科医生在实践中可能会面临周边不连续强化病变的挑战。本文旨在回顾可能显示不连续周边强化的良性和恶性局灶性肝脏病变的范围。一个特别令人感兴趣的点是诊断树路径，它可以指导放射科医生进行鉴别诊断。© 2024。作者。
The discontinuous peripheral enhancement is a pattern of enhancement usually attributed to typical cavernous hemangioma, that is the most common benign solid lesion of the liver. The discontinuous peripheral enhancement, however, may be encountered in many other benign and malignant focal liver lesions as an atypical presentation or evolution, and hemangiomas with discontinuous peripheral hyperenhancement on hepatic arterial phase may not always have the typical post-contrast pattern on portal venous and delayed phases. Therefore, abdominal radiologists may be challenged in their practice by lesions with discontinuous peripheral enhancement. This pictorial essay aims to review the spectrum of benign and malignant focal liver lesions that may show discontinuous peripheral enhancement. A particular point of interest is the diagnostic tree pathway that may guide the radiologists in the differential diagnosis.© 2024. The Author(s).
