目的：探讨眼眶套细胞淋巴瘤（MCL）的彩色多普勒超声特征，为本病的诊断提供参考。方法：回顾性分析2005年12月—2015年5月医院收治的12例（16只眼）眼眶MCL患者临床资料，采用彩色多普勒超声仪对患者进行检查，观察瘤体的体积、位置、形状、边界、回声及与周围组织关系，再观察彩色多普勒血流显示情况，测量舒张期最低流速（Vmin）、收缩期最高流速（Vmax）、阻力指数（Resistance index，RI）。结果：12例眼眶MCL患者中有10例在低回声区内可见分散的条索状强回声，并沿肌椎外间隙生长，2例表现为低回声，提高增益后仍可探及细弱的分隔。炎性假瘤肿块多位于球后眶内，并向前后蔓延；超声可见球筋膜囊水肿，双侧眼外肌明显增粗；其眼外肌增厚，呈低回声区，声衰逐渐减少。眼眶MCL肿块内血流信号丰富，内部血流纵横交错，峰值流速较高；炎性假瘤肿块内血流信号较为丰富，主要表现为有规律的分支血流；其中MCL组Vmin、Vmax、RI均显著高于炎性假瘤组（P＜0.05）。结论： 眼眶MCL超声存在一定规律， 同时结合患者临床表现、 发病部位有助于眼眶MCL的诊断。

Objective: To explore the color Doppler ultrasound features of the orbital mantle cell lymphoma(MCL), and to provide a reference for the diagnosis of the disease. Methods: A total of 12 cases(16 eyes) orbital MCL patients treated in hospital from May 2005 to December 2015 clinical data were retrospectively analyzed, examination of patients by color Doppler ultrasound, observed the umor size, location, shape, boundary, echo and relationship with the surrounding tissue, and then detected color Doppler blood flow display, for blood flow display, measured diastolic minimum velocity(Vmin), peak systolic velocity(Vmax), resistance index(RI). Results: Twelve cases of orbital MCL patients with 10 cases in the low echo area scattered the rope shaped strong echo, and the gres of along the muscle vertebra clearance, 2 cases showed low echo, improve gain can still be detected, and thin separated. The inflammatory tumor mass was found in many of the posterior orbital, and spread to the front and back. The ultrasound showed the swelling of the capsule, and the bilateral lateral muscle was significantly increased. Orbital MCL mass flow signal were rich, inflammatory pseudotumor tumor blood flow signal was very rich, mainly for regular branch flow. The Vmax, Vmin, and RI in MCL group were significantly higher than those in inflammatory pseudo tumor group(P<0.05). Conclusion: There are certain regularity ultrasound in the orbital MCL, and combine clinical manifestations and tumor location are helpful to the diagnosis of MCL.
