Developmental venous anomalies (DVAs) are considered to be congenital anatomical variants of venous drainage. In most cases unspecific symptoms lead to their diagnosis. We describe a 35-year-old patient presenting with headache and dizziness. MRI was suspicious for arteriovenous malformation and the dorsal horn of the right lateral ventricle was enlarged. Digital subtraction angiography showed complex venous malformations with abnormal supratentorial venous drainage and bilateral cerebellar DVAs with associated varix nodes. This is a unique case of complex supra- and infratentorial abnormal venous drainage. After considering the complexity of these venous anomalies and the fact that the patient was asymptomatic there was no reasonable indication for treatment.
发育性静脉异常（DVAs）被认为是静脉引流的先天性解剖变异。在大多数情况下，非特异性症状导致其被诊断出来。我们描述了一名35岁出现头痛和头晕的患者。磁共振成像（MRI）怀疑有动静脉畸形，右侧脑室后角增大。数字减影血管造影显示复杂的静脉畸形，伴有幕上异常静脉引流以及双侧小脑发育性静脉异常并伴有静脉曲张结节。这是一例独特的幕上和幕下复杂异常静脉引流病例。考虑到这些静脉异常的复杂性以及患者无症状这一事实，没有合理的治疗指征。
