Extensive Intracranial Arteriovenous Malformation in a Child with Aplasia Cutis Congenita.

We report on a child with multiple lesions of membranous aplasia cutis congenita of the scalp since birth who developed an extensive intracranial arteriovenous malformation several years later. Even in the absence of other clues to suggest intracranial anomalies, children with multiple scalp defects should be carefully surveyed and followed up in the long term.
