We recently encountered two large intrasellar arachnoid cysts extending to the suprasellar region. The intensity of the cyst contents was identical to that of the cerebrospinal fluid on both T1- and T2- weighted MRI. On contrast-enhanced MRI, the pituitary gland was compressed posteroinferiorly and flattened in the sella turcica. In this report of rare intrasellar arachnoid cysts the discussion is focused on dislocation of the pituitary gland.
我们最近遇到了两例巨大的鞍内蛛网膜囊肿，囊肿延伸至鞍上区域。在T1加权和T2加权磁共振成像（MRI）上，囊肿内容物的信号强度与脑脊液相同。在增强MRI上，垂体被向后下方压迫，在蝶鞍内变平。在这份关于罕见鞍内蛛网膜囊肿的报告中，讨论的重点是垂体的移位。
