The authors report their classification of venous anomalies and abnormalities within the central nervous system. The so-called venous angiomas are developmental venous anomalies (D.V.A.). The different forms encountered express the extreme variations in the transcerebral venous system. Their symptomatic character depends on the aging changes that the cerebral venous system undergoes or the frequent association of D.V.A. with cavernomas of the central nervous system. The cavernous hemangiomas are true tumors that present a proliferative character. They are localized in the dura or in the extradural space intracranially or at the spinal level. They must be considered as tumors and can be seen at angiography as they present a fine parenchymatous stain. The cavernomas of the central nervous system are true vascular malformations of the venous type; they are locally multiple, but can also be disseminated within the intracranial space. Some familial forms have been reported. They are often associated with D.V.A. They have a high bleeding potential, which does not carry a high morbidity or mortality incidence. However, the natural history of this lesion is poorly known at present. The spinal cord posterior fossa and paraventricular localizations present probably the least favorable localizations. Only the cavernomas deserve to belong to the vascular malformation group. The same comments and observations apply to spinal cord venous lesions.
作者报告了他们对中枢神经系统内静脉异常的分类。所谓的静脉血管瘤是发育性静脉异常（D.V.A.）。所遇到的不同形式表现出经脑静脉系统的极端变异。它们的症状特征取决于脑静脉系统所经历的老化变化，或D.V.A.与中枢神经系统海绵状血管瘤的频繁关联。海绵状血管瘤是具有增殖特征的真性肿瘤。它们位于硬脑膜内或颅内硬膜外间隙或脊髓水平。它们必须被视为肿瘤，在血管造影时可见，因为它们呈现出细微的实质染色。中枢神经系统的海绵状血管瘤是真正的静脉型血管畸形；它们局部多发，但也可在颅内空间播散。已有一些家族性病例报道。它们常与D.V.A.相关。它们有很高的出血潜能，但发病率和死亡率并不高。然而，目前对这种病变的自然史了解甚少。脊髓后颅窝和脑室旁定位可能是最不利的定位。只有海绵状血管瘤才属于血管畸形组。同样的评论和观察适用于脊髓静脉病变。
