目的分析肝肺吸虫病的超声造影特点,提高超声造影对肝肺吸虫病的诊断水平。方法选择2011年6月至2015年12月在四川大学华西医院行超声造影检查并经手术病理或穿刺活组织检查证实为肝肺吸虫病27例患者,其中男性17例,女性10例;年龄24~60岁,平均年龄43.0岁。使用Philips i U22型超声诊断仪进行超声造影,回顾性分析肝肺吸虫病的超声造影特点。结果 27个病灶中14个(51.85%)在动脉期呈高增强,其中8个(29.63%)门静脉期和延迟期均呈低增强,3个(11.11%)门静脉期呈等增强,延迟期呈低增强;3个(11.11%)门静脉期及延迟期均呈等增强;6个病灶(22.22%)在动脉期呈等增强,其中4个(14.81%)门静脉期呈等增强,延迟期呈低增强;2个(7.41%)门静脉期和延迟期均呈等增强。7个病灶(25.93%)呈3个时相低/无增强。不同病灶在动脉期增强形态不同,14个高增强病灶均表现为不均匀增强伴部分坏死,其中9个周边可见环状强化;6个等增强病灶中2个(7.41%)动脉期呈整体均匀增强,4个(14.81%)呈不均匀增强,其中2个周边可见环状强化。病灶内部坏死形态以隧道样改变为主(48.15%)。结论肝肺吸虫病的超声造影表现具有多样性,超声造影能较好地评估肝肺吸虫病的血流灌注特征,提高对肝肺吸虫病的诊断能力。
Objective To analyze the characteristics of liver paragonimiasis by contrast-enhanced ultrasound and to improve the diagnostic value of contrast-enhanced ultrasound on liver and paragonimiasis. METHODS: From June 2011 to December 2015, 27 patients with liver-paragonimiasis were confirmed by ultrasonography in West China Hospital of Sichuan University and confirmed by pathology or biopsy. There were 17 males and 10 females, aged 24 ~ 60 years old, average age 43.0 years old. Uses the Philips U22 ultrasonic diagnostic apparatus to carry on the ultrasonography, retrospectively analyzes the characteristic of hepatic paragonimiasis. Results Fourteen of the 27 lesions (51.85%) were highly enhanced in the arterial phase. Eight of them (29.63%) showed a low enhancement in the portal venous phase and delayed phase and three (11.11%) showed an equal increase in the portal venous phase with a delay of 6 cases (22.22%) showed equal enhancement in the arterial phase, of which 4 (14.81%) showed equal enhancement in the portal vein phase and a low delay period Enhanced; 2 (7.41%) portal venous phase and delayed phase showed an equal increase. Seven lesions (25.93%) showed low / no enhancement at three phases. Different lesions in the arterial phase enhanced morphology, 14 high-enhanced lesions showed uneven enhancement with partial necrosis, of which 9 peripheral enhancement seen ring; 2 of 6 enhanced lesions in 2 (7.41%) were uniform throughout the arterial phase Enhanced, 4 (14.81%) showed uneven enhancement, of which 2 can be seen around the annular enhancement. The internal necrosis of the lesion was dominated by tunnel-like changes (48.15%). Conclusion The results of contrast-enhanced ultrasound in the detection of hepatic paragonimiasis are quite diverse. CEUS can better evaluate the perfusion characteristics of liver paragonimiasis and improve the diagnosis of hepatic paragonimiasis.
