The perihepatic space is frequently involved in a spectrum of diseases, including intrahepatic lesions extending to the liver capsule and disease conditions involving adjacent organs extending to the perihepatic space or spreading thanks to the communication from intraperitoneal or extraperitoneal sites through the hepatic ligaments. Lesions resulting from the dissemination of peritoneal processes may also affect the perihepatic space. Here we discuss how to assess the perihepatic origin of a lesion and describe the magnetic resonance imaging (MRI) features of normal structures and fluids that may be abnormally located in the perihepatic space. We then review and illustrate the MRI findings present in cases of perihepatic infectious, tumor-related, and miscellaneous conditions. Finally, we highlight the value of MRI over computed tomography.
肝周间隙常累及一系列疾病，包括延伸至肝包膜的肝内病变以及累及相邻器官并延伸至肝周间隙的疾病状态，或因腹腔内或腹膜外部位通过肝韧带相通而蔓延至肝周间隙的疾病。腹膜病变播散所致的病变也可能影响肝周间隙。在此，我们讨论如何评估病变的肝周起源，并描述正常结构和液体在肝周间隙异常定位时的磁共振成像（MRI）特征。然后，我们回顾并举例说明肝周感染、肿瘤相关及其他情况的MRI表现。最后，我们强调MRI相对于计算机断层扫描的价值。
