CASE
A 28-year-old woman developed gait disturbance due to lower limb weakness 3 years before presentation. Conventional magnetic resonance imaging (MRI) findings were inconclusive; therefore, we performed cine MRI, which confirmed the presence of a pulsatile cyst on the posterior thoracic spinal cord. The cyst compressed the spinal cord, and its pulsations synchronized with the patient's heartbeats. We resected the intradural arachnoid cyst and thickened arachnoid membrane. The gait disturbance improved after surgery.
CONCLUSIONS
Cine MRI can be used to identify a pulsating arachnoid cyst that cannot be visualized with a conventional MRI. Cine MRI is useful in patients with unexplained spinal symptoms.
病例
一名 28 岁女性，在出现症状前 3 年出现下肢无力导致步态障碍。常规磁共振成像（MRI）检查结果不确定；因此，我们进行电影 MRI 检查，结果证实存在位于胸段脊髓后部的搏动性蛛网膜囊肿。该囊肿压迫脊髓，其搏动与患者的心跳同步。我们切除了硬脊膜内蛛网膜囊肿和增厚的蛛网膜。术后步态障碍改善。
结论
电影 MRI 可用于识别常规 MRI 无法显示的搏动性蛛网膜囊肿。电影 MRI 对不明原因的脊髓症状患者有用。
