BACKGROUND
We report a rare case of arachnoid cyst incorporating choroid plexus. This 7-month-old girl presented with macrocrania. Magnetic resonance (MR) imaging disclosed a cystic lesion arising from the left prepontine cistern extending to the left middle cranial fossa.
METHODS
First, we performed resection of the membrane microscopically and obtained an adequate reduction of the cystic size. However, 4 months after the first operation, the cyst was enlarged again, and bulging of the portion of the craniotomy was noted. Thus, we performed neuroendoscopic transcortical ventriculo-cyst-cysternostomy and confirmed the choroid plexus inside of the arachnoid cyst.
DISCUSSION
Postoperative course was uneventful. This is the first reported case of choroid plexus within an arachnoid cyst, determined neuroendoscopically.
背景
我们报告一例罕见的包含脉络丛的蛛网膜囊肿病例。这名7个月大的女孩表现为巨颅症。磁共振成像显示一个囊性病变，起源于左桥前池并延伸至左中颅窝。
方法
首先，我们在显微镜下切除了囊肿包膜，使囊肿大小得到了充分减小。然而，首次手术后4个月，囊肿再次增大，且开颅部位出现膨隆。因此，我们进行了神经内镜经皮质脑室-囊肿-脑池造瘘术，并证实蛛网膜囊肿内有脉络丛。
讨论
术后过程顺利。这是首例经神经内镜确定蛛网膜囊肿内存在脉络丛的报道病例。
