: Solitary necrotic nodules of the liver can be multiple and usually appear as hypovascular nodules mimicking hepatic metastases, but they are relatively small and located in the subcapsular areas of the liver. We report a very rare case of multiple solitary necrotic nodules of the liver mimicking hepatic metastases in a patient with previous history of lung cancer. The lesions appeared as low-attenuated or low-signal intensity nodules with thin rim enhancement on both contrast-enhanced computed tomography (CT) and magnetic resonance (MR) imaging, making them difficult to differentiate from hepatic metastases. This rare benign entity should be kept in mind, especially when lesions are small and located in the subcapsular areas of the liver.
肝脏孤立性坏死结节可为多发，通常表现为类似肝转移瘤的乏血供结节，但它们相对较小，位于肝脏的包膜下区域。我们报告了1例既往有肺癌病史的患者出现酷似肝转移瘤的多发肝脏孤立性坏死结节的罕见病例。在对比增强计算机断层扫描（CT）和磁共振（MR）成像上，这些病变均表现为低衰减或低信号强度结节，并伴有薄环状强化，这使得它们难以与肝转移瘤相鉴别。尤其是当病变较小且位于肝脏包膜下区域时，应牢记这种罕见的良性病变。
