摘　　要：目的:探讨MSCT脑室造影在婴幼儿颅脑疾病中的诊断价值及临床意义。材料和方法:对30例CT平扫发现脑室扩大的患儿进行经脑室造影后CT扫描,并进行多平面重建。结果:9例为单纯性脑积水(其中6例为梗阻性脑积水,3例为交通性脑积水),8例侧脑室局限性扩大(其中4例为侧脑室囊肿,4例为侧脑室单纯性局限性扩大),7例颅后窝囊肿(其中1例为Dandy-Walker综合征,1例为小脑蚓部囊肿,5例为枕大池囊肿),5例鞍上囊肿,1例脑穿通畸形。结论:MSCT脑室造影不仪有助于侧脑室单纯性局限性囊性扩大与脑室囊肿的鉴别,有助于鞍上囊肿与第三脑室囊性扩大的鉴别,有助于颅后窝囊肿的鉴别,而且在婴幼儿脑室扩大的病因诊断中具有较高的诊断价值。Purpose： To explore the value and clinical usefulness of MSCT - ventriculography in the diagnosis of intracranial disease of nurseling. Materials and Methods： 30 patients received the MSCT - ventriculography whose dilated ventriculus were found on plan CT scanning, and the images were reconstructed on post- processing station with multiplannar reformation. Results： On MSCT -ventriculography, 9 simple hydrocephalus （6 obstructive hydrocephalus, 3 communicating hydrocephalus）, 8 diagnosed as ventricular dilatation（4 ventricular cyst, 4 local ventricular dilatation）, 7 diagnosed as cyst of posterior cranial fossa（1 Dandy - Walker syndrome , 1 arachnoid cyst of vermis of cerebellum, 5 arach- noid cyst cisterna magna ）, 5 diagnosed as arachnoid cyst of suprasellar cistern, and 1 porencephaly were diagnosed. Conclusion： MSCT - ventriculography can distinguish local ventricular dilatation and ventricular cyst, suprasellar cistern and cystic dilatation of third ventricle of cerebrum, cystic diseases of posterior cranial fossa, and is valuable in etiological diagnosis of ventricular dilatation of nurseling.
