摘要
目的：探讨肝孤立性坏死结节的临床、病理形态学特点、影像学及其鉴别诊断，以期对此疾病进行更加深入的理解。方法：收集临床资料并结合影像学及病理形态学检查结果，运用光镜及特染技术研究1例肝孤立性坏死结节并系统进行相关文献复习。结果：影像学、B超、CT、MRI检查均表现为边界尚清楚的低回声、低密度、低信号结节，且增强扫描后内部不强化。MRI增强后病灶环形强化。镜下结节为一粉染无结构的非干酪样坏死物构成，其内未见细菌、寄生虫等病原体入侵。结节周围可见透明变性纤维包膜包绕。病变周围为正常肝组织。病理诊断：肝孤立性坏死结节。结论：肝孤立性坏死结节有特异影像学和病理组织学表现，临床治疗方案为病灶切除，术后预后良好，不易复发。

Abstract
Objective: To investigate the clinicopathological, imaging features and differential diagnosis of solitary necrotic nodule (SNN) of the liver. Methods: Clinical data were collected and combined radiological findings. One case of SNN of the liver was studied by light microscopy and special staining technique with system relevant literature review. Results: Combine US, CT, and MRI, displayed low echo, low dense, and without significant enhancement. Enhanced MRI lesions showed ring enhancement. The liver SNN had a completely necrotic core with fibrous capsule, no parasite or atypical cell was identified. The surrounding parenchyma was normal. Conclusion: Liver SNN has special radiological and pathological features. Clinical treatment is local excision with good progression and without recurrence.
