A case of an isodense non-enhancing colloid cyst of the third ventricle which was not easily diagnosed by computed tomography is described. The patient underwent magnetic resonance imaging which clearly showed a colloid cyst of the third ventricle with accompanying obstructive hydrocephalus. Such lesions are potentially life-threatening if undiagnosed. It is suggested that magnetic resonance imaging has an important role to play in rapidly and clearly demonstrating the location, size and complications of such lesions when there is doubt about the aetiology of obstructive hydrocephalus of the lateral ventricles on computed tomography.
本文描述了一例第三脑室等密度、无强化的胶样囊肿病例，该病例通过计算机断层扫描不易诊断。患者接受了磁共振成像检查，结果清楚地显示出第三脑室胶样囊肿并伴有梗阻性脑积水。此类病变若未被诊断，可能会危及生命。建议当对计算机断层扫描显示的侧脑室梗阻性脑积水的病因存在疑问时，磁共振成像在快速、清晰地显示此类病变的位置、大小及并发症方面具有重要作用。
