Cerebral venous angioma (CVA) is an embryonic venous malformation. Its incidence was thought to be radiologically rare previously but with greater clinical awareness, the routine use of contrast enhanced computerised tomography (CECT) and the increasing availability of magnetic resonance imaging (MRI), it is no longer perceived to be a rare lesion. In fact, it is the commonest intracranial vascular malformation seen at autopsy. We report our experience of 15 patients with cerebral venous angiomas, 14 of whom had their lesions confirmed by cerebral angiography. Presentation was variable and non-specific. The commonest presenting symptom was headache (n = 7). Other clinical presentations included epilepsy (n = 5), intracerebral bleed (n = 4, two were thought to be due to an associated cerebral cavernous angioma and one was due to a ruptured arteriovenous malformation) and non-specific giddiness (n = 3). Six were diagnosed incidentally. Based on the angiographic findings and the relatively benign clinical course in the majority of our patients, we believe that CVA is a developmental anomaly and should not be excised routinely.
脑静脉血管瘤（CVA）是一种胚胎性静脉畸形。以前认为其发病率在影像学上较为罕见，但随着临床认识的提高、对比增强计算机断层扫描（CECT）的常规使用以及磁共振成像（MRI）的日益普及，它不再被视为罕见病变。事实上，它是尸检中最常见的颅内血管畸形。我们报告了15例脑静脉血管瘤患者的经验，其中14例通过脑血管造影证实有病变。临床表现多样且不具特异性。最常见的症状是头痛（n = 7）。其他临床表现包括癫痫（n = 5）、脑出血（n = 4，其中两例被认为是由于合并的脑海绵状血管瘤，一例是由于动静脉畸形破裂）和非特异性头晕（n = 3）。6例为偶然诊断。基于血管造影结果以及我们大多数患者相对良性的临床病程，我们认为CVA是一种发育异常，不应常规切除。
