眼内猪囊尾蚴病的超声诊断特征

摘要

目的：探讨眼内猪囊尾蚴病的彩色多普勒超声诊断特征。方法回顾分析临床诊断并经手术、病理证实为眼内猪囊尾蚴病的患者11例(11眼)，对其彩色多普勒超声特征进行分析，并根据术中所见判断超声诊断的准确性。结果11例患者(11眼)中玻璃体囊尾蚴7例(7眼)，视网膜下囊尾蚴4例(4眼)。眼内囊尾蚴的超声表现为玻璃体腔内或视网膜下的类圆形囊样中强回声，其内为无回声区，并伴有偏心的团状强回声。合并玻璃体积血或炎症的患者，玻璃体腔内出现弱点状、絮状或条状回声；合并视网膜脱离的患者，玻璃体内可测及与视盘或球壁相连的带状回声。彩色多普勒示囊尾蚴的类圆形囊样回声、其内的团状强回声以及玻璃体内的点状、絮状及条状回声上均未见血流信号；合并视网膜脱离的患者可在脱离的视网膜带状回声上测及与视网膜中央动、静脉相延续的血流信号。结论眼内猪囊尾蚴有特征性的超声表现，为临床提供可靠的诊断和鉴别诊断依据。%Objective To investigate the characteristic of the B-mode ultrasonography and the color Doppler flow imaging diagnosis for intraocular cysticercosis.Methods Eleven eyes of 1 1 patients diagnosed of intraocular cysticercosis clinically and confirmed by operation and pathology were retrospectively studied. Their B-mode ultrasonography and color Doppler flow imaging were analyzed.Surgery diagosis was also reviewed.Results Among 1 1 eyes of 1 1 patients,intravitreal cysticercus presented in 7 cases (7 eyes),and 4 cases (4 eyes)diagnosed of subretinal cysticercus.Intraocular cysticercosis showed a round or oval vesicle-like echogenic mass in the vitreous body or under the retina,and the high-level echo spot in it was the scolex. Some dot and stripe echo and retinal detachment also appeared in the vitreous cavity with vitreous inflammation.The blood flow signal was detected in retinal detachment with color Doppler flow imaging. Conclusions Ultrasonography is extremely useful in the diagnosis of intraocular cysticercosis and the findings can be pathognomonic.
