Preoperative diagnosis of intracranial cysts has been simplified and made more rapid and accurate with computed tomography (CT). By means of conventional CT and CT metrizamide ventriculography, the position and communication of intracranial cysts with the ventricular system and subarachnoid space or cisterns can be demonstrated. Suprasellar arachnoid cysts can produce significant neurologic and endocrinologic abnormalities due to their position. They are a surgically curable cause of hydrocephalus. Preoperative differentiation from aqueduct stenosis or other causes of a large third ventricle is important. The usefulness of coronal CT and CT metrizamide ventriculography in the investigation of these lesions is illustrated in six patients.
计算机断层扫描（CT）使颅内囊肿的术前诊断变得更加简便、快速且准确。通过传统CT和CT脑池造影术，可以显示颅内囊肿与脑室系统、蛛网膜下腔或脑池的位置及连通情况。鞍上蛛网膜囊肿因其位置可导致明显的神经和内分泌异常。它们是脑积水的一种可通过手术治愈的病因。术前鉴别其与导水管狭窄或其他导致第三脑室扩大的病因很重要。六例患者的情况说明了冠状位CT和CT脑池造影术在这些病变检查中的作用。
