目的分析肝结核CT动态增强的CT表现，探讨CT动态增强在肝结核诊断和鉴别诊断。方法回顾性分析11例肝结核CT动态增强表现。结果11例中粟粒性肝结核1例，局限性肝结核5例，结核瘤型肝结核4例，肝包膜结核1例。粟粒性肝结核：（1）肝密度偏低不均匀，（2）增强在正常肝组织对比下可见弥漫性大小不一粟粒状、小结节状低密度灶；局限性肝结核：（1）平扫单发或多发结节状、片状低密度灶，（2）增强病灶各期边缘轻到中度强化，（3）中心不均匀轻度强化或无强化；结核瘤型肝结核：（1）平扫呈结节状低密度灶，（2）增强动脉期无或轻度周围强化，（3）门脉期病灶周围环形轻到中度强化（4）均有延迟强化，（5）病灶中心各期均无强化。结论 CT动态增强对肝结核诊断有较高诊断价值，结合临床和肝外结核病史多可以做出诊断。

ObjectiveTo evaluate the diagnostic value of dynamic contrast-enhanced CT in hepatic tuberculosis(TB).Methods CT of 11 patients with hepatic TB was analyzed retrospectively.Results Of 11 patients, the TB was miliary(1), localized(5), tuberculoma(4) or capsular(1). Miliary hepatic TB showed heterogeneous low density or diffuse hypodense micronodules of varying size. Localized TB appeared as solitary or multiple nodular and flaky hypodense foci with mild to moderate border enhancement in all phases, mild or no enhancement in the center. Tuberculomas were hypodense nodules with mild or no rim enhancement in the arterial phase, mild to moderate enhancement in the venous phase, persistent delayed enhancement, and no enhancement in the center.Conclusion Dynamic contrast-enhanced CT can aid diagnosis of hepatic TB combined with clinical history.
