PHACE(S) Syndrome Minus the H: A Case of Possible PHACE(S) Syndrome Without an Infantile Hemangioma.

A 4-month-old, full-term girl was referred for evaluation of a supraumbilical raphe and an anomalous aortic arch. Further work up for PHACE(S) syndrome was pursued, despite the absence of a cutaneous infantile hemangioma (IH), which identified hypoplastic and dysplastic cerebral vasculature. We present this case to raise awareness of possible PHACE(S) syndrome even in children without cutaneous IHs and the importance of recognizing supraumbilical raphe as a sentinel finding.
