摘要
目的观察儿童郎格罕细胞组织细胞增生症(LCH)腹部超声表现。方法回顾性分析28例经病理证实的LCH患儿腹部超声资料。结果 28例中,25例LCH累及多系统,3例仅累及肝胆。28例肝脏均不同程度增大,肝实质内部回声不均匀,可见散在或弥漫性低回声区,其中13例伴胆管壁广泛性不均匀性增厚、回声增强,胆管腔局部扩张或局部狭窄。17例伴脾肿大,5例伴胰腺肿大,13例伴不同程度腹腔积液,14例伴肝门区淋巴结肿大。结论儿童LCH腹部超声表现具有一定特征性,有助于提高诊断准确率。
Objective To observe the abdominal ultrasonic manifestations of children with Langerhans cells histiocytosis（LCH）.Methods Imaging features of histopathologically proved LCH in 28 children were retrospectively analyzed.Results Among 28 cases,multi-system involvement was found in 25 cases,while only liver and bile duct involvement were detected in 3 cases.Different degrees of enlarged liver,inhomogeneous echo of liver parenchyma,scattered or diffuse hypoechoic regions were found in all 28 cases.Uneven thickening and echo enhancement of the bile duct wall,as well as local expansion or stricture of bile duct cavity were found in 13 cases.Splenomegaly was found in 17 cases,swelling of the pancreas was found in 5 cases,varying degrees of ascites were found in 13 cases,and hepatic hilar lymphadenectasis were found in 14 cases.Conclusion There are specific ultrasonographic manifestations of LCH in children,which may be helpful to improving diagnostic accuracy of LCH.
