Abstract：
De novo arterio-venous malformations (AVMs) of the brain have been rarely previously reported, especially in the pediatric population. Although AVMs have possible connections with other diseases, the association with congenital portosystemic shunt (CPSS) has never been reported before. A child was followed for CPSS and cutaneous and hepatic angiomas. Brain MRI and angiography revealed an AVM within the left temporal region that was not present at a previous MRI. The patient underwent successful resection of the AVM. This case adds new evidence on the complex variety of diseases associated with multisystemic vascular malformations corroborating the hypothesis of a multifactorial origin of de novo cerebral AVMs, under a possible common genetic substrate.
摘要：
大脑从头动静脉畸形（AVM）以前很少报道，尤其是在儿科人群中。尽管AVM可能与其他疾病有关，与先天性门体分流术(CPSS)的相关性以前从未报道过.随访一名儿童进行CPSS以及皮肤和肝血管瘤。脑部MRI和血管造影显示左颞区存在AVM，以前的MRI不存在。患者成功切除了AVM。这个案例增加了与多系统血管畸形相关的复杂疾病的新证据，证实了从头脑AVM的多因素起源的假设。在可能的共同遗传底物下。
