Segmental biliary obstruction as a result of primary or secondary hepatic malignancy has been reported with increasing frequency. For two representative patients, the clinical and Tc-99m HIDA scintigraphic findings in segmental biliary obstruction are described. The presence of photon-deficient dilated bile ducts in one segment of the biliary tree is highly suggestive of localized biliary obstruction and should be considered in the patient with suspected or proven hepatic malignancy despite the absence of jaundice.
原发性或继发性肝脏恶性肿瘤导致的节段性胆管梗阻的报道日益增多。本文描述了两名具有代表性患者节段性胆管梗阻的临床及99m锝-亚氨基二乙酸（Tc-99m HIDA）闪烁扫描结果。胆管树某一节段出现光子缺乏性扩张胆管高度提示存在局限性胆管梗阻，对于疑似或已证实患有肝脏恶性肿瘤的患者，即便无黄疸也应考虑这一情况。
