To evaluate the MR findings of ganglion cysts of the cruciate ligaments in correlation with clinical findings.
We reviewed 12 patients with ganglion cysts of the cruciate ligaments obtained from a medical record of 4153 consecutive patients referred for knee MR examinations. All patients presented with chronic knee pain and 4 had restriction of knee motion. The MR imaging findings of the cysts were evaluated and correlated with clinical manifestations.
Seven ganglion cysts were found in the posterior cruciate ligaments and 5 in the anterior cruciate ligaments. All cysts were lobulated (n=7) or fusiform (n=5) in shape, 1.8-4.5 cm in size, along the posterior surface in the proximal or distal end of the ligaments. Ten patients had arthroscopic resection or aspiration of their cysts, became symptom free and had no recurrence on follow-up MR examinations. Two cysts reduced in size spontaneously by conservative treatment.
MR imaging can offer useful information in detection and diagnosis of patients with chronic knee pain due to ganglion cysts of the cruciate ligaments. The size and location of the ganglion cysts can attribute to the clinical manifestations.
评估交叉韧带腱鞘囊肿的磁共振成像（MR）表现及其与临床表现的相关性。
我们回顾了4153例因膝关节MR检查而连续就诊的患者病历，其中12例患有交叉韧带腱鞘囊肿。所有患者均有慢性膝关节疼痛，4例存在膝关节活动受限。对囊肿的MR成像表现进行评估，并与临床表现相关联。
在后交叉韧带中发现7个腱鞘囊肿，在前交叉韧带中发现5个。所有囊肿均呈分叶状（n = 7）或梭形（n = 5），大小为1.8 - 4.5厘米，位于韧带近端或远端的后表面。10例患者接受了关节镜下囊肿切除术或穿刺抽吸，症状消失，随访MR检查无复发。2例囊肿经保守治疗后自行缩小。
MR成像可为诊断因交叉韧带腱鞘囊肿导致慢性膝关节疼痛的患者提供有用信息。腱鞘囊肿的大小和位置可归因于临床表现。
