交叉韧带囊肿MR影像与临床表现分析

目的:分析交叉韧带囊肿的MR影像和临床表现。方法:对7例交叉韧带囊肿患者进行回顾性分析,其中男性5例,女性2例。年龄22~38岁(平均年龄30.6岁)。对所有患者的临床表现,包括症状、症状持续时间、体征、外伤病史以及MR影像进行了分析。结果:本组病例有5例前交叉韧带囊肿和2例后交叉韧带囊肿,所有囊肿形态为椭圆形或分叶状。大多数位于交叉韧带的后方。采用关节镜手术对所有患者的囊肿进行切除和吸取,术后症状消失并且经过随访未出现复发。结论:膝关节内的交叉韧带囊肿较为少见。它可能造成膝关节疼痛,屈伸功能受限。MRI检查是有助于确立诊断、指导治疗的有效手段。这类损伤经过关节镜手术治疗可获得满意疗效。

Analysis of MR Findings with the Clinical Feature in Patients with Cruciate Ligament Cysts

Objective To evaluate the MRI findings of the cruciate ligaments cysts in correlation with clinical feature.Methods Seven patients with cruciate ligaments cysts were reviewed. There were 5 men and 2 women, aged from 22 to 38 years (mean 30.6 years). All patients were examined by the knee MRI. The clinical manifestations such as symptoms, duration of symptoms, sign, and the history of trauma were evaluated and then correlated with the MRI findings.Results Five ganglion cysts were found in the anterior cruciate ligaments and 2 in the posterior cruciate ligaments. All cysts were either oval or lobulated in shape. Most of them were located along the posterior surface of the ligaments. All cysts were resected or aspirated through arthroscopy. After surgery, all patients were asymptomatic without recurrence during follow-up.Conclusion Intraarticular cysts of the cruciate ligaments are uncommon. It can cause knee pain, limitation of knee extension and flexion. The unique MR images of the cysts help to diagnose patients with chronic knee pain, as well as to plan the treatment. The results of arthroscopic treatment for the cysts were satisfied.
