静脉血管瘤(Venous angioma)是一种比较少见的先天性血管畸形,脑和脊髓均可发生,以脊髓为常见。80％患者发生在20～60岁之间,男性多于女性。在颅内,静脉血管瘤主要发生在大脑中动脉分布区、大脑大静脉引流的脑中央区,小脑也可受累,也有发生在脉络丛。颅内静脉血管瘤可无症状,故检出率很低,尽管在尸解中并非罕见,但通常被认为是一种少见的先天性疾患。 Venous angioma (Venous angioma) is a relatively rare congenital vascular malformations, can occur in the brain and spinal cord, the spinal cord is common. 80% of patients occur between 20 and 60 years of age, more men than women. In the intracranial and venous hemangiomas occur mainly in the distribution of the middle cerebral artery, central cerebral ventricles drained by the cerebral venules, the cerebellum may also be involved, but also occur in the choroid plexus. Intracranial venous hemangioma can be asymptomatic, so the detection rate is very low, although not uncommon in the autopsy, but is generally considered a rare congenital disorders.
