摘要
目的探讨眼眶原发性黏膜相关淋巴组织结外边缘区B细胞淋巴瘤的磁共振(MRI)信号特点。方法回顾性分析2010年9月至2017年8月10例经临床病理证实的眼眶原发黏膜相关淋巴瘤的MRI信号特点,10例均行MRI平扫,8例行MRI增强扫描。结果其中,单结节型5例,发生于眼睑2例,发生于眼球后方3例;弥漫型5例,发生于眼肌、肌间隙及球后。MRI信号T1WI呈等或稍高信号为主,T2WI呈等或稍高信号为主,信号均匀。8例行增强扫描,病灶呈中度至重度均匀强化。结论眼眶原发黏膜相关淋巴组织淋巴瘤MRI多数表现为T1WI等信号或稍高信号,T2WI等信号或稍高信号,增强扫描明显强化,包绕眼球生长具有一定的特征性。
Objective To investigate the magnetic resonance imaging(MRI)signal characteristics of primary mucosal associated lymphoma tissue lymphoma of the orbit.Methods MRI signal characteristics of 10 cases of orbital mucosal associated lymphoma tissue lymphoma between Sep.2010 and Aug.2017 were retrospectively analysed.All cases were confirmed by clinicopathology.MRI plain scan was performed in 10 cases and among them enhanced MRI scan was performed in 8 cases.Results There were 5 cases of single nodule type and 5 cases of diffuse type.Two cases of single nodule type occurred in the eyelid,and 3 cases of single of nodule type occurred in the rear of the eyeball.The diffuse type occurred in the eye muscle,intermuscular space and retrobulbar.MRI signal,T1WI presented equal or slightly high signal,and T2WI presented equal or slightly high signal,and the signal was uniform.The lesion of 8 cases who underwent enhanced scanning presented moderate to severe uniform enhancement.Conclusion The primary orbital mucosal associated lymphoma MRI shows equal or slightly higher signal intensity on T1WI and equal or slightly higher signal intensity on T2WI,which is significantly enhanced by enhanced scanning and shows some characteristics of encircling eyeball growth.
