The 2nd case of local skin adverse effect A Three-dimensional computed tomographic(CT) angiography showed an abnormally expanded blood vessel mass (white arrow) in the soft tissue above the left orbit, supplied by the left superficial temporal artery, temporal artery (white arrow with dark outline) and arteria angularis (black arrow). The malformed blood vessel was not adjacent to the eyeball. B. CT imaging showed subcutaneous soft tissue mass in the upper left eyelid and forehead. C. Enhanced CT scan showed the vessel mass significantly heterogenous contrast enhancement. D. Surgical debulking was performed via a skin incision below the supraorbital ridge. White arrow indicates the solidified vascular malformation after medical glue injection. Black arrow indicates the exposed frontal bone after complete resection of the malformed blood vessel. E. CT scan showed the skin in the lateral-superior region of left orbit was slightly thickened at three months after surgery. Comparison of the pre-operation imaging the malformed blood vessel lesion was absent
