目的探讨眼眶肌锥内占位性病变的病理组织学类型与影像学表现之间的相互关系.方法收集近三年间诊治的52例肌锥内占位性病变患者的临床资料和组织标本切片,回顾性分析其病理学类型及影像学表现.结果眼眶肌锥内良性占位病变52例,主要为血管源性病变37例,其中海绵状血管瘤(25例)占总体的48.1％,CT多表现为类圆形占位,边界清楚,均匀软组织密度,强化明显,动态扫描可呈渐进性强化,平扫CT值均大于50 HU,CDFI显示未见明显血流信号；8例神经源性病变中神经鞘瘤(5例)占总体的9.6％,CT多表现为圆形或椭圆形占位影,边界清楚,密度均匀或不均匀,平扫CT值在35～50 HU之间,偶可见特征性的“小尾巴”状影,CDFI显示较丰富血流信号,呈低速低阻型血流频谱；此外,炎性病变、囊性病变及淋巴组织增生性病变比例(分别为7.7％、3.8％、1.9％)及CT、彩色多普勒的表现均存在异同.资料中未见恶性病变.结论眼眶肌锥内占位性病变以良性为主,其中血管源性病变占据较大比例.CT、彩色多普勒检查技术对判断肌锥内占位性病变的性质、病变范围具有重要意义.

Objective To investigate the relation between pathology and imaging findings in the orbital intracone lesions.Methods The clinical materials and sample slices of 52 patients with intracone lesions were collected,and retrospectively analyzed the pathological types and imaging findings.Results Fifty-two cases of the orbital intracone benign lesions,mainly vasogenic lesions (37 cases),including cavemous hemangioma of the total proportion of about 48.1％ (25 cases).In the CT-scan,the round space-occupying lesions,a clear boundary,uniform middle density,marked enhancement,dynamic scan showed progressive enhancement.CDFI showed no flow signal; in the 8 cases neurogenic lesions,nerve sheath tumors accounted for a larger proportion of about 9.6％ (5 cases),CT more performance for the round or ovalplaceholder shaped shadow,clear boundary,homogeneous or inhomogeneous density,the CT values between the 35-50HU,even visible characteristic "tail"-like shadow,CDFI showed rich blood flow signal and low-speed low resistance blood flowspectrum.In addition,the inflammatory lesions,cystic lesions and lymphoproliferative lesions might also occur in the orbital intracone.Conclusion The majority of orbital intracone lesions are benign,and vasogenic lesions have a large proportion.Therefore,the imaging techniques including CT,B ultrasound,and Color doppler ultrasound,have the significant value in the diagnosis or prognosis of lacrimal sac lesions.
