目的探讨睫状体脉络膜脱离的影像表现特点及诊断价值.方法回顾性分析19例睫状体脉络膜脱离(包括浆液性睫状体脉络膜脱离9例、脉络膜血肿7例和单纯睫状体脱离3例)的超声、MRI和CT表现,所有患者均行超声和MR检查,11例行CT检查.结果浆液性睫状体脉络膜脱离超声(9例)表现为眼球壁膜状隆起,范围不等,其后连赤道或视盘附近球壁,前界无法探及,膜下为无回声液性暗区;MRI(9例)示眼环鼻侧、颞侧均可见脱离薄膜,前界不超越睫状体眼环附着部,后缘止于眼环后部,脱离薄膜下为长T1、长T2液体信号;CT(5例)表现为眼环轻度增厚,眼球密度轻微增高.脉络膜血肿超声(7例)表现为眼球壁半球形或弧形膜状隆起突向玻璃体腔,膜下为大量弱回声光点;MRI(7例)和CT(5例)表现为眼环后部或眼环鼻、颞侧半球形、梭形及弧形隆起,CT呈等或稍高密度,T1WI和T2WI呈中或高信号;其中1例血肿区T2WI见分层信号表现.单纯睫状体脱离除超声(3例)发现异常外,Mm(3例)和CT(1例)无异常发现.结论影像检查可为睫状体脉络膜脱离的诊断提供可靠依据.

Objective To investigate the characteristics of imaging appearances and diagnostic value of ciliochoroidal detachment.Methods Ultrasound,MRI and CT appearances of 19 cases of ciliochoroidal detachment were reviewed,which included 9 cases of serous ciliochoroidal detachment,7 cases of choroid hematoma,and 3 cases of ciliary body detachment.All cases were examined by both B ultrasound and MRI at the same time,11 of them were examined by CT.Results UItrasound showed membrane bulge of the eyeball wall with different extent in 9 cases of serous ciliochoroidal detachment.Its postzone connected the equator or close to optic disc and its prozone could not been detected by ultrasound.There was echofree fluid darkspace under detached membrane.MRI showed membrane detachment at both nasal side and temporal side of ocular annulation in 9 cases of ciliochoroidal detachment.The detached membrane was approximately symmetry,its anterior margin did not exceed ciliary body adhesion of ocular annnlation and its posterior margin stopped at posterior part of ocular annulafion.There was long T1 and long T2 signal under detached membrane.CT showed slight thickening of ocular annulafion and slightly increased density of eyeball in 5 cases of serous cilioehoroidal detachment.Ultrasound showed hemispheroid or curve bulge of eyeball wall,projected toward the vitreous cavity in 7 cases of choroid hematoma,and there was an amount of low echo light spot under the detached membrane.Both MRI (7 cases)and CT (5 cases) showed hemispheroid,fusfform or curve bulge on the nasal side,temporal side and posterior part of ocular annulation.They appeared as isodensity or slight high density on CT,iso- or high signal on T1 WI and T2WI.Stratification was seen on T2WI in I case of choroid hematoma.Ciliary body detachment could not been detected by either MBI (3 cases) or CT (1 case) except ultrasound.Conclusion Imaging examination may provide reliable diagnostic evidence for ciliochoroidal detachment.
