PURPOSE: To present a case of a child with an extensive facial hemangioma in whom the suspicion of intracranial involvement was raised by visual evoked potential (VEP) evaluation. DESIGN: Observational case report. METHODS: VEP analysis was performed using flash and pattern stimuli to determine whether treatment intervention other than occlusion therapy was needed. RESULTS: VEP analysis indicate d a marked transoccipital asymmetry in the flash and pattern VEP suggestive of r ight hemispheric dysfunction. Neuroimaging showed intracranial extension of the hemangioma. CONCLUSION: The VEP evaluation is a noninvasive technique performed in the awake child. This case highlights the usefulness of VEP analysis in the m anagement of extensive periocular capillary hemangiomas and its use as a modalit y to identify potential intracranial involvement. Large plaquelike facial capill ary hemangiomas may have possible underlying dural involvement suggestive of PHA CES syndrome.
