(A) A purple, telangiectatic, centrally depressed mass with pale margins was found behind the left ear at birth. (B) The mass shrank 2 weeks after arterial embolization. (C) The mass had almost completely resolved by 3 months of age, leaving a telangiectatic scar with halo margins.

The lesion was purple in color and had a telangiectatic appearance with a central depression and pale margins (Figure 1A). Due to stable condition, he was discharged from the hospital on day 18 (Figure 1B). At 3 months, the hemangioma had almost completely regressed, leaving a halo-shaped telangiectatic scar (Figure 1C), and then sirolimus was shifted to propranolol.
(A) Magnetic resonance imaging showed a well-defined margin, vascular-rich lesion with a central scar. (B) Selected left common arteriography demonstrated a clear boundary, uniform staining mass with a feeder artery from the internal carotid artery to the mass without collateral artery to adjacent organs (arrow). (C) Repeat arteriography after arterial embolization using multiple coils shows no residual shunt (arrow).

Magnetic resonance imaging (MRI) on the seventh day of life revealed a well-defined margin, T2 high-intensity signals, flow voids, a vascular-rich lesion with a central scar, no intracranial extension or involvement of adjacent tissues, and confirmed the presence of a hemangioma (Figure 2A). Selective left common carotid arteriography demonstrated a clear boundary, uniform parenchymal staining mass with a single large feeder artery from the internal carotid artery (Figure 2B). Repeat arteriography showed no obvious residual shunt after embolization (Figure 2C).
