Adult liver Langerhans cell histiocytosis (LCH) is an extremely rare desease. This paper reports a 40 years old male patient who was diagnosed as liver LCH though ultrasound-guided liver biopsy. The initial Fluorrine-18- fluorodeoxyglucose positron emission tomography/ computed tomography (F-FDG PET/CT) showed multiple nodular low-density lesions in liver without obvious elevated F-FDG uptake. Four years later, the follow-up F-FDG PET/CT showed the liver multiple lesions with slightly elevated F-FDG uptake.
We describe this case, to highlight the importance of F-FDG PET/CT in differential diagnosis for the primary disease and the multiple liver nodules.
成人肝脏朗格汉斯细胞组织细胞增多症（LCH）是一种极其罕见的疾病。本文报告一名40岁男性患者，经超声引导下肝脏活检被诊断为肝脏LCH。最初的氟-18-氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（F-FDG PET/CT）显示肝脏有多个结节状低密度病变，F-FDG摄取无明显升高。四年后，随访的F-FDG PET/CT显示肝脏多处病变，F-FDG摄取略有升高。
我们描述此病例，以强调F-FDG PET/CT在原发性疾病和肝脏多发结节鉴别诊断中的重要性。
