Cine-magnetic resonance (MR) imaging examinations were performed in 10 patients with middle cranial fossa arachnoid cysts to evaluate communication between the cysts and the normal cerebrospinal fluid (CSF) space. Eight of 10 patients were evaluated by time of flight cine-MR imaging, and two by phase contrast cine-MR imaging. Two patients underwent membranectomy of the cysts, and were evaluated both pre- and postoperatively. Computed tomography cisternography was used to confirm communication between the cysts and the surrounding cisterns. Pulsatile fluid motion within the cysts was present in all patients. However, marked fluid motion and jet flow between the cysts and the surrounding cisterns were only observed in communicating cysts. In the two patients who underwent membranectomy, postoperative examination found greater fluid motion and jet flow not previously present. Cine-MR imaging demonstration of marked pulsatile fluid motion accompanied by jet flow suggests that a cyst communicates with the normal CSF space.
对10例中颅窝蛛网膜囊肿患者进行了电影磁共振（MR）成像检查，以评估囊肿与正常脑脊液（CSF）间隙之间的连通情况。10例患者中有8例通过飞行时间电影MR成像进行评估，2例通过相位对比电影MR成像进行评估。2例患者接受了囊肿膜切除术，并在术前和术后进行了评估。计算机断层扫描脑池造影用于确认囊肿与周围脑池之间的连通情况。所有患者的囊肿内均存在搏动性液体流动。然而，仅在交通性囊肿中观察到囊肿与周围脑池之间明显的液体流动和喷射流。在接受囊肿膜切除术的2例患者中，术后检查发现有先前不存在的更大的液体流动和喷射流。电影MR成像显示明显的搏动性液体流动并伴有喷射流，提示囊肿与正常CSF间隙相通。
