Periportal lesions were detected on ultrasound in two cases of Langerhans cell histiocytosis with liver involvement. Hypoechoic or hyperechoic lesions were detected in different stages of evolution. Hyperechoic lesions probably corresponded to periportal inflammation whilst hyperechogenicity suggested xanthomatous change.
在两例伴有肝脏受累的朗格汉斯细胞组织细胞增多症患者中，超声检查发现了门周病变。在不同的病变发展阶段检测到低回声或高回声病变。高回声病变可能与门周炎症有关，而高回声性提示有黄色瘤样改变。
