摘要
目的:探讨牵牛花综合征的临床和影像学特征及其诊断价值。方法:回顾分析8例牵牛花综合征患者的临床及影像学资料。结果:牵牛花综合征的主要影像学表现:CT平扫示眼环视神经附着处变薄致玻璃体向眼球后壁呈球形突出;眼底荧光造影检查示早期视盘弱荧光,中晚期视盘周围动静脉显示清楚,晚期视盘荧光着染;B超检查示玻璃体腔暗区向后极部延伸至视乳头处并突向肌锥底部,玻璃体腔后部呈倒置的瓶颈状回声图像,部分患者可见视网膜脱离光带;A超显示玻璃体腔与瓶颈部一致的无回声暗区均为较平直的基线。结论:CT、超声、眼底荧光造影从不同的方面显示了牵牛花综合征的影像学特征,是正确诊断牵牛花综合征的可靠影像学手段。
Objective： To discuss the clinical setting and imaging features of morning glory syndrome. Methods： The clinical setting,CT, ultrasonography and fundus Fluorescein angiography （FFA） features were retrospectively analyzed in 8 cases of morning glory syndrome. Results： The CT characteristics of morning glory syndrome were as follows., attachment spot of optic nerve was thinned, spherical shaped protrusion of vitreous body toward the posterior wall can be seen. In the early phase of FFA, hypofluorescence on the optic disc can be revealed;abnormal arteries and veins around the optic papilla can be clearly displayed when the focus was adjusted to the periphery of the optic disc. In the advanced phase,optic discs were dyed with fluorescein. On the B-mode ultrasonography the dark anechoic area of vitreous cavity extended to the posterior pole and optic papilla, projecting toward the basal part of muscle cone, showing a converted bottleneck shaped posterior part of vitreous cavity. Sometimes the ＂light ribbon＂ appearance of retinal detachment can also be seen. On the A-mode ultrasonography, both vitreous cavity and the ＂bottle-neck area＂ showed anechoic without any evidence of wave crest. Conclusion： Imaging characteristics of morning glory syndrome can be revealed by CT,ultrasonography and FFA manifesting from different aspects, which was helpful＇for the diagnosis and differential diagnosis.
