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 eases,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.
