摘要
目的:报告7例肝结核并结合有关文献讨论肝结核的CT表现。材料和方法:报告的7例患者均经手术或肝穿病理证实。男3例,女4例;年龄24~58岁(平均50岁)。其中包括粟粒型肝结核、结节型肝结核和结核性胆管炎三个病理类型。结果:(1)粟粒型肝结核CT表现为肝脏弥漫性肿大、密度减低或表现为肝脏肿大伴有多发性粟粒状低密度灶,增强扫描无明显强化。(2)结节型肝结核可表现为肝内局灶性低密度区,增强扫描可有周边性强化;亦可表现为肝内结节状混杂密度灶,其特点是病灶中心密度高,尤其是伴有“粉末”状钙化,周围密度低,增强扫描有轻至中度的环形强化。(3)结核性胆管炎罕见,沿胆管壁走行的钙化、管型结石可能是本病的特点。结论:粟粒型肝结核CT表现缺乏特征性,除非有结核病史或伴有其他脏器结核,否则CT不能做出正确诊断。结节型肝结核和结核性胆管炎的CT表现有一定的特征性,可提示肝结核的诊断。
