Solitary necrotic nodule of the liver is a rare entity of unknown aetiology. We describe the case of a 59-year-old woman reporting sporadic right upper quadrant pain. An abdominal CT scan revealed a liver nodule located in segment 4. The complementary investigation was unable to identify the neoplastic lesion, and its surgical resection was performed, with an uneventful recovery. Pathological examination revealed a 'solitary necrotic nodule of the liver.' The patient remains asymptomatic and free of recurrence 3 years after surgery. This case corroborates that despite the advances in liver imaging and biopsy, liver nodules are sometimes a diagnostic challenge; quite often, only its surgical resection allows a definitive diagnosis.
肝脏孤立性坏死结节是一种病因不明的罕见病症。我们报告了一例59岁女性，她自述有偶发的右上腹疼痛。腹部CT扫描显示肝脏结节位于4段。进一步检查未能明确肿瘤性病变，遂进行了手术切除，术后恢复顺利。病理检查显示为“肝脏孤立性坏死结节”。患者术后3年仍无症状且未复发。该病例证实，尽管肝脏成像和活检技术有所进步，但肝脏结节有时仍是诊断难题；很多时候，只有通过手术切除才能做出明确诊断。
