摘　　要：目的分析眼附属器淋巴瘤(OAL)的磁共振成像(MRI)特点,提高人们对该疾病的认识。方法回顾性分析2014年7月至2019年7月经手术病理证实的35例(38只眼)OAL患者的MRI特点。结果单眼发病32例(91.4%),双眼发病3例(8.6%),累及眼睑、结膜18只眼(47.4%),累及泪腺14只眼(36.8%),累及泪囊9只眼(23.7%),累及眼外肌9只眼(23.7%),累及2个以上部位23只眼(60.5%)。以眼外肌为参照,T1WI等信号29只眼(76.3%),稍高信号9只眼(23.7%);T2WI等信号26只眼(68.4%),稍高信号12只眼(31.6%),其内见低信号流空影4只眼(10.5%),伴发同侧副鼻窦炎症10只眼(26.3%);增强扫描轻度强化20只眼(52.6%),中度强化12只眼(31.6%),明显强化6只眼(15.8%);包绕眼球且未侵及球内结构32只眼(84.2%),其中30只眼球壁不变形。结论OAL的MRI表现有一定的特征性,单眼多见,好发于眶隔前组织,并向眶内侵犯,多部位受侵,弥漫性铸型生长,易包绕眼球但眼球不变形是其特点,信号多均匀,增强扫描多呈轻-中度均匀强化。Objective To analyze the magnetic resonance imaging(MRI)features of ocular adnexal lymphoma(OAL)and improve the understanding of the disease for people.Methods MRI features of OAL patients in 35 cases(38 eyes)confirmed by surgical pathology from July 2014 to July 2019 were retrospectively analyzed.Results There were 32 cases(91.4%)with one eye invoived,3 cases(8.6%)with both eyes involoved,eyelid and conjunctiva involved in 18 eyes(47.4%),lacrimal gland involved in 14 eyes(36.8%),lacrimal sac involoved in 9 eyes(23.7%),extraocular muscle involved in 9 eyes(23.7%)and 23 eyes(60.5%)involved more than 2 locations.Taking the extraocular muscle as the reference,29 eyes(76.3%)had equal signal intensity on T1WI,9 eyes(23.7%)had slightly higher signal intensity;26 eyes(68.4%)had equal signal intensity on T2WI,12 eyes(31.6%)had slightly higher signal intensity,4 eyes(10.5%)had low signal flow shadow,10 eyes(26.3%)had concomitant sinusitis on the same side;20 eyes(52.6%)had slight enhancement by enhanced scans,12 eyes(31.6%)had moderate enhancement,and 6 eyes had significant enhancement;32 eyes(84.2%)were surrounded by the eyeball without invading the inner structure of the ball,and 30 eyes had no deformation of the ball wall.Conclusion The OAL has certain characteristics in MRI manifestations,mostly monocular,it is prone to occur in the anterior tissue of orbital septum and invade many locations of the orbit,diffuse cast growth,easy to wrap around the eyeball but the eyeball is not deformed.The signal shows more uniform,and the enhanced scan shows more light-medium uniform enhancement.
