摘要
目的总结肝脏孤立性坏死结节的超声造影表现。方法回顾性分析了10例经病理确诊的肝脏孤立性坏死结节患者的超声造影表现。结果 8例肝脏孤立性坏死结节病灶超声造影动脉期、门脉期、实质期均无增强,呈边界清晰的造影剂充盈缺损区。2例病灶超声造影动脉早期周边可见环状增强,于动脉晚期消退,门脉期、实质期内部无增强。结论肝脏孤立性坏死结节具有特征性的超声造影表现,超声造影对肝脏坏死性结节有较高诊断的价值。
Objective To investigate the value of contrast-enhanced ultrasonography （CEUS） in diagnosis of solitary necrotic liver nodule. Methods Ten pathologically proven solitary necrotic liver nodules were retrospectively analysed by CEUS. Results Eight lesions were described as well-defined perfusion defects throughout all phases on CEUS, two lesions had peripheral rim enhancement in early arterial phase which disappeared after late arterial phase. No enhancement was detected in the portal and parenchymal phase. Conclusion The olitary necrotic liver nodule has characteristic manifestation on CEUS. CEUS is valuable for diagnosis of solitary necrotic liver nodule.
