Abstract

Ventricular tumor is relatively rare and clinical diagnosis of this tumor is seldom possible and diagnosis depends upon neuroradiological studies, Among neuroradiological studies ventriculography is a primary diagnostic method in the anatomical localization of the ventricular tumor, however, cerebral angiography is also helpful indelineating the vascular supply of the ventricular lesion and aid in the surgical treatment, and the pathologic nature of some of these tumors can be identified by angiography. Seven cases of supratentorial ventricular tumors which were confiremd at Seoul National University Hospital during last four years were presented with operative and pathological findings. The authors attempt to make a certain angiographic criteria of choroidal arteries forlocalization and determination of pathological nature of the ventricular tumor, based on the anatomic distribution and character of vascular change of choroidal arteris. The results are as follows; 1. Anatomical localization ofthe ventricular tumor can be exectly determined by evaluation of changes of choroidal arteries. Blind spots inlocalization of the ventricular tumor by cerebral angiography are third ventricle and frontal horn of the lateral ventricle which have poor vascular supply. 2. Highly vascular ventricular tumors are meningioma and ependymoma inour series, however, differentiation betwen these tumors can be seldom possible by cerebral angiography. Astrocytoma is a hypovascular tumor.
