Colloid cysts are relatively rare intracranial lesions located in the rostral aspect of the third ventricle. They may produce acute hydrocephalus, brain herniation, and lead to death. Although the clinical and imaging features of colloid cysts are well known, their etiology and the factors responsible for their imaging features continue to be a subject of debate. We present the imaging-pathologic correlation of a patient with a colloid cyst as well as data supporting the fact that the presence of cholesterol is probably responsible for the MR imaging features exhibited by some colloid cysts.
胶样囊肿是位于第三脑室前部的相对罕见的颅内病变。它们可能导致急性脑积水、脑疝，并可导致死亡。尽管胶样囊肿的临床和影像学特征已为人熟知，但其病因以及导致其影像学特征的因素仍是一个争论的话题。我们展示了一例胶样囊肿患者的影像-病理相关性，以及支持胆固醇的存在可能是一些胶样囊肿所表现出的磁共振成像特征的原因这一事实的数据。
