Pial fistula in infancy: Report of two cases and literature review with special emphasis on the ruptured group

摘要

Cerebral pial fistula is a rare vascular pathology with no more than 150 cases reported. Most cases reported in infancy have been published as case reports. Owing to its high flow, its occurrence in this age group carries the potential risk of heart failure, chronic venous hypertension, seizures and, less frequently, cerebral haemorrhage.
