The authors retrospectively analyzed the angiographic findings performed in 17 cases with central neurocytoma to document the angiographic characteristics and suggested the origin of tumor based on the angiographic findings. Their medical records and radiological investigations were reviewed and cerebral angiographies were thoroughly examined in arterial, capillary, and venous phases. In ten cases, marked or moderate tumor staining was found whereas the staining was either scanty or absent in seven cases. In the ten cases showing marked or moderate tumor staining, the feeding vessels were originated from the ipsilateral carotid and/or vertebro-basilar system. In the venous phase, the ipsilateral thalamostriate vein, tortuous and enlarged, was elevated, and the internal cerebral vein was depressed. Thus, the venous angle of the ipsilateral side was widened at an irregular contour. Based on the characteristic displacement and the increased size of the associated venous system, it is suggested that the central neurocytoma might originate from a neuronal cell mass of the subependymal zone located on the floor of the lateral ventricle around the foramen of Monro rather than from the septum pellucidum.
作者回顾性分析了17例中枢神经细胞瘤的血管造影结果，以记录血管造影特征，并根据血管造影结果推测肿瘤的起源。回顾了他们的病历和影像学检查，并对脑血管造影的动脉期、毛细血管期和静脉期进行了全面检查。10例出现明显或中度肿瘤染色，而7例染色稀少或无染色。在10例显示明显或中度肿瘤染色的病例中，供血血管起源于同侧颈内动脉和/或椎基底动脉系统。在静脉期，同侧丘脑纹状体静脉迂曲增粗并抬高，大脑内静脉压低。因此，同侧静脉角增宽，轮廓不规则。基于相关静脉系统的特征性移位和增大，提示中枢神经细胞瘤可能起源于位于侧脑室底部围绕室间孔的室管膜下区的神经元细胞团，而非透明隔。
