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。
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 ifndings. 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 signiifcant enhancement. Enhanced MRI lesions showed ring enhancement. The liver SNN had a completely necrotic core with fibrous capsule, no parasite or atypical cell was identiifed. hTe surrounding parenchyma was normal. Conclusion：Liver SNN has special radiological and pathological features. Clinical treatment is local excision with good progression and without recurrence.
