Cerebral varices are intracranial venous anomalies that are characterized as thin-walled vessels, with a single layer of endothelium lining it and a thin lamina or fibrous connective tissue surrounding it. These varices are usually associated with vascular abnormalities such as arteriovenous malformations or developmental venous anomalies, but may rarely be found as isolated lesions as well. Diagnosis of these isolated lesions on imaging is a challenge, because it is a rare entity and can mimic a space occupying lesion in the brain. The patients with isolated cerebral varix can present with neurological symptoms; however, majority are asymptomatic with the diagnosis made incidentally.
The aim of this study is to report a case of a 21-month-old boy who was diagnosed with an isolated cerebral varix and had presented with delayed milestones in addition to seizures. His MRI scans showed a solid-cum-cystic lesion with contrast enhancing walls that was excised through craniotomy. Postoperatively, he regained his milestones.
The patients with isolated cerebral varix can present with neurological symptoms; however, majority are asymptomatic with the diagnosis made incidentally. These patients have a low risk of bleeding and are treated conservatively, with surgical intervention indicated only in symptomatic patients.
脑静脉曲张是一种颅内静脉异常，其特征为薄壁血管，内有单层内皮细胞衬里，周围有薄层或纤维结缔组织。这些静脉曲张通常与血管异常相关，如动静脉畸形或发育性静脉异常，但也可能很少作为孤立性病变出现。在影像学上诊断这些孤立性病变具有挑战性，因为它是一种罕见的实体，可能会被误诊为脑部占位性病变。孤立性脑静脉曲张患者可能出现神经症状；然而，大多数患者无症状，诊断是偶然发现的。
本研究的目的是报告一例21个月大的男孩，他被诊断为孤立性脑静脉曲张，除癫痫发作外还出现发育迟缓。他的MRI扫描显示一个实性兼囊性病变，壁有强化，通过开颅手术切除。术后，他恢复了发育。
孤立性脑静脉曲张患者可能出现神经症状；然而，大多数患者无症状，诊断是偶然发现的。这些患者出血风险低，采用保守治疗，仅对有症状的患者进行手术干预。
