Background

Developmental venous anomalies are considered benign lesions; however, they can become symptomatic. A capillary stain, which is an atypical angiographical feature of developmental venous anomalies, is reported to be relevant to symptomatic developmental venous anomalies.

Case description

A 20-year-old man with no pertinent medical history had an epileptic seizure. Magnetic resonance imaging showed severe focal oedema and gadolinium contrast enhancement in the right precentral gyrus and inferior frontal gyrus adjacent to the Sylvian fissure, indicating venous congestion; these presentations had not been observed on magnetic resonance imaging 8 months before. Digital subtraction angiography revealed a developmental venous anomaly with capillary stain. After conservative treatment, the brain oedema resolved spontaneously and contrast enhancement of the lesion reduced significantly.

Conclusion

We report a rare case of a symptomatic developmental venous anomaly with unique radiological characteristics and its natural and clinical evolution. Despite the presence of a capillary stain, our patient exhibited temporary exacerbations and spontaneous regression, suggesting that the capillary stain was associated with a reversible condition. This is the first report to detail the spatiotemporal changes of a developmental venous anomaly with capillary stain through imaging, suggesting that regular follow-up imaging is warranted in the management of patients with developmental venous anomalies.

有毛细血管染色的有症状的发育性静脉异常的自发消退

背景

发育性静脉异常被认为是良性病变；但是，它们可能会出现症状。据报道，毛细血管染色是发育性静脉异常的非典型血管造影特征，与有症状的发育性静脉异常有关。

案例描述

一名没有相关病史的 20 岁男性癫痫发作。磁共振成像显示右侧中央前回和靠近外侧裂的额下回严重局灶性水肿和钆造影增强，表明静脉充血；这些表现在 8 个月前未在磁共振成像中观察到。数字减影血管造影显示有毛细血管染色的发育性静脉异常。经保守治疗后，脑水肿自行消退，病灶对比增强显着减弱。

结论

我们报告了一例罕见的有症状的发育性静脉异常病例，具有独特的放射学特征及其自然和临床演变。尽管存在毛细血管染色，但我们的患者表现出暂时性加重和自发消退，表明毛细血管染色与可逆病症相关。这是第一份通过成像详细说明发育性静脉异常伴毛细血管染色的时空变化的报告，表明在治疗发育性静脉异常患者时需要定期随访成像。
