Pial arteriovenous fistulas (pAVF) of the posterior fossa are rare and may present with symptoms secondary to mass effect, venous hypertension or hemorrhage, among others. A case is presented of a previously healthy 2-year-old boy with neurological deficit arising from pAVF of the posteroinferior cerebellar artery. The pAVF was successfully treated with endovascular occlusion.
