【摘要】：目的探讨儿童朗格罕细胞组织细胞增生症(LCH)肝脏损伤的MRI表现及诊断价值。方法回顾性分析10例经病理证实的儿童LCH肝脏损伤患儿的临床及MRI资料,10例均行MRI平扫加增强,7例行磁共振胰胆管成像(MRCP)检查。结果 (1)常规MRI表现:肝右叶局灶性病变1例,肝门汇管区受累1例,肝门汇管区合并肝叶受累8例,其中合并肝左叶受累2例,全肝弥漫性受累5例,肝门淋巴结肿大8例。肝门汇管区异常信号8例,表现为轴位上与门静脉伴行条状长T1、长T2信号5例,合并结节状短T1脂肪信号3例;肝实质内片状长T1、长T2信号3例,多发结节状长T1、长T2信号5例,囊状信号2例,扩散加权成像(DWI)序列病变高信号6例。增强后病变不强化2例,环状强化5例,片絮状强化3例。(2)MRCP表现:累及肝总管及右肝管2例,胆总管及肝总管2例,肝总管及左、右肝管1例,左、右肝管2例,继发远端胆管扩张6例。(3)MRI分级:Ⅰ级1例,Ⅱ级1例,Ⅲ级3例,Ⅳ级5例。结论儿童LCH肝脏损伤具有相对特征性MRI表现,正确认识其特点可以为临床治疗方案的选择提供重要依据。
[Abstract]:Objective to investigate the MRI findings and diagnostic value of (LCH) liver injury in children with Langerhans cell histiocytosis. Methods the clinical and MRI data of 10 children with LCH liver injury confirmed by pathology were retrospectively analyzed. MRI plain scan and enhancement were performed in 10 cases and (MRCP) examination on Mr cholangiopancreatography was performed in 7 cases. Results (1) conventional MRI findings included 1 case of focal lesions in the right lobe of the liver, 1 case of hepatic portal junction area, 8 cases of hepatic portal area with hepatic lobe involvement, including 2 cases with hepatic Zuo Ye involvement, 5 cases with diffuse hepatic involvement and 8 cases with hilar lymph node enlargement. Abnormal signal intensity in portal area of liver was found in 8 cases, showing long T 1, long T 2 signal in 5 cases and nodular short T 1 fat signal in 3 cases, flake long T 1 and long T 2 signal intensity in 3 cases of hepatic parenchyma, long T 1, long T 2 signal intensity in 3 cases of hepatic parenchyma, long T 1, long T 2 signal intensity in 3 cases. Multiple nodular long T 1, long T 2 signal in 5 cases, cystic signal in 2 cases, and high signal intensity in 6 cases on diffusion-weighted (DWI) sequence. (2) MRCP findings included common hepatic duct and right hepatic duct in 2 cases, common bile duct and common hepatic duct in 2 cases, common hepatic duct and left and right hepatic duct in 1 case, left and right hepatic duct in 2 cases, and left and right hepatic duct in 2 cases. (3) MRI classification: 1 case of grade 鈪，
