Lobar atrophy of the liver due to causes other than liver tumor or liver cirrhosis is a relatively rare pathological condition, and there are only a few reports in the literature. We report six such cases and try to evaluate the relationship between lobar atrophy and portal flow disturbance. The patients could be divided into two groups according to the site of the atrophy: those with atrophy of the left lobe (two cases) and those with atrophy of the right lobe (four cases). The two cases with atrophy of the right lobe had hepatholithiasis in the involved segments, but the cause was not determined in the remaining four cases. In all six cases, portal flow disturbance was noted, including invisibility of the portal vein in four cases, narrowing in one case, and portal thrombus in one case. Collateral circulation was not recognized in any of our cases. Of interest is the mode of lobar atrophy. Atrophy of the right lobe was always associated with marked enlargement of the left lobe, but that of the left lobe did not induce an enlargement of the right lobe.
由肝肿瘤或肝硬化以外的原因引起的肝叶萎缩是一种相对罕见的病理状况，文献中仅有少数报道。我们报告6例此类病例，并试图评估肝叶萎缩与门静脉血流紊乱之间的关系。根据萎缩部位，患者可分为两组：左叶萎缩患者（2例）和右叶萎缩患者（4例）。右叶萎缩的2例患者在受累节段有肝内胆管结石，但其余4例病因未明。6例均发现门静脉血流紊乱，包括4例门静脉不可见、1例狭窄和1例门静脉血栓形成。我们的病例中均未发现侧支循环。有趣的是肝叶萎缩的方式。右叶萎缩总是伴有左叶明显增大，但左叶萎缩并未导致右叶增大。
