Periportal region is an anatomic space around portal vein comprising hepatic artery, bile duct, nerves, lymphatics and a potential space. Periportal pathologies may involve any of these structures diffusely or focally with characteristic radiologic findings. Radiologic findings can be helpful in differential diagnosis of pathologies of periportal structures including periportal cavernomatous transformation, hepatic artery aneurysm, biliary diseases, neurofibromatosis, lymphoma, langerhans' cell histiocytosis, periportal fatty infiltration and other causes of periportal halo in adult and pediatric patients. Lobar/segmental intrahepatic involvement can be seen in neurofibromatosis, cavernomatous transformation, fatty infiltration and periportal edema. In this review, we discuss CT and MRI findings of periportal pathologies which can be in the form of diffuse or segmental/lobar involvement.
门周区域是门静脉周围的一个解剖间隙，包含肝动脉、胆管、神经、淋巴管以及一个潜在间隙。门周病变可弥漫性或局灶性累及这些结构中的任何一个，并具有特征性的影像学表现。影像学表现有助于对门周结构病变进行鉴别诊断，包括门周海绵样变性、肝动脉瘤、胆道疾病、神经纤维瘤病、淋巴瘤、朗格汉斯细胞组织细胞增多症、门周脂肪浸润以及成人和儿童患者门周晕圈的其他病因。神经纤维瘤病、海绵样变性、脂肪浸润和门周水肿可见肝叶/肝段内受累。在本综述中，我们讨论门周病变的CT和MRI表现，这些病变可以是弥漫性或节段性/叶性累及的形式。
