Persistent stapedial artery in PHACE syndrome.

INTRODUCTION: PHACE syndrome is characterized by posterior fossa malformations, haemangioma, arterial anomalies, coarctation of the aorta, and eye abnormalities.

CASE REPORT: We present the case of a 6-year-old girl followed since birth for PHACE syndrome and left hemifacial haemangioma, who presented with left hearing loss. Computed tomography scan showed left persistent stapedial artery (PSA).

DISCUSSION: Two types of arterial anomalies may be observed in PHACE syndrome: persistence of embryonic arteries and anomalies of cerebral arteries. PSA can be observed in the context of PHACE syndrome. Children with PHACE syndrome require regular audiometric follow-up to detect hearing loss and avoid its consequences on speech and language development.
