摘要
目的探讨肝硬化梗死再生结节的CT表现。方法回顾性分析经病理证实的5例肝硬化梗死再生结节患者的CT表现及临床资料。结果 5例患者均于食道或胃底静脉曲张出血后就诊。多数病灶呈圆形,病灶数目均大于10枚,直径0.5~2.0 cm,病灶边界多清晰,多位于肝周边邻近肝包膜下。4例结节呈簇状分布,1例呈散在分布,病灶均呈低密度,增强扫描边缘强化。1例3周后复查,之前所见结节消失。结论肝硬化梗死再生结节多发生于上消化道出血后。CT检查多表现为肝脏周边近包膜下簇状分布的多发、小而呈圆形的低密度灶,增强扫描病灶边缘强化,在一段时间的CT随访中,病灶可消失或大小有所缩小,这些有助于其诊断与鉴别诊断。
Objective To investigate the CT findings of infarcted regenerative nodules in patients with liver cirrhosis.Methods All CT features and clinical data of five patients with histologically proved infarcted regenerative nodules were retrospectively analyzed.Results All of five patients were admitted to emergency room after esophagus or gastric fundus variceal bleeding.Most of the lesions were round in shape,more than ten in number.The size of the nodules ranged from 0.5 cm to 2.0 cm.The lesions had mostly well-defined margins and were present in the periphery.Four cases had clustered distribution and one case had scattered distribution.All of the nodular lesions were seen as hypoattenuating with rim enhancement.In one case,the nodules which were seen previously,disappered three weeks after the event.Conclusion Infarcted regenerative nodules in liver cirrhosis occur predominantly after upper gastrointestinal hemorrhage.On CT examination,most of the lesions were located in the subcapsular areas of liver,and present as multiple,small,round,clustered distribution hypoattenuated with rim enhancement; After a period of time,On the follow-up CT,the nodules may disappear or decrease in size,which is useful for diagnosis and differential diagnosis.
