We report the appearance of a cavernous malformation associated with a developmental venous anomaly in a young boy 3 years after radiation therapy for a posterior fossa medulloblastoma. The presence of a stenosis of the venous drainage of the anomaly led us to postulate that venous restrictive disease, induced by radiation therapy, resulted in increased venous pressure and caused the formation of the cavernous malformation.
我们报告了一名小男孩在接受后颅窝髓母细胞瘤放射治疗3年后出现了与发育性静脉异常相关的海绵状畸形。该异常静脉引流存在狭窄,这使我们推测放射治疗引起的静脉限制性疾病导致静脉压力升高,并引发了海绵状畸形的形成。
