摘要：肝结核较罕见，因缺乏典型的临床症状及体征，临床诊断较困难。继发性肝结核较常
见，肝内症状少见，因肝外症状就诊者居多，主要病理表现为肉芽肿性病变，可见干酪样坏
死及郎格罕细胞。影像学检查对肝结核的诊断率较高，超声造影作为一种近年来迅速发展的
诊断方法，因其方便、实时、诊断率高而在临床广泛使用。发生肝结核时，超声造影的增强
模式可表现为动脉期不均匀低增强和延迟期的低增强，结合临床病史及相关检查，对于肝脏
肿瘤性质的鉴别有重要的诊断价值。

Abstract: Hepatic tuberculosis is a relatively rare disease, as its clinical symptoms and signs are lack
of typical, the clinical diagnosis is difficult. Secondary hepatic tuberculosis is relatively common,
intrahepatic symptoms are rare and most are extrahepatic symptoms. The main pathological feature is
granulomatous inflammation, the caseous necrosis and Langham’s cells can also be observed. Imaging
examination has a high diagnosis rate of hepatic tuberculosis. In recent years, ultrasound contrast has
developed rapidly. It has been widely used because of its convenience, real-time and high diagnostic
rate. For hepatic tuberculosis, contrast enhancement mode of ultrasound showed low enhancement of
arterial phase and delayed phase. Combined with clinical history and related examination, ultrasound
contrast has important diagnostic value for the nature tumor.
