Radiation-induced alopecia after fluoroscopically guided procedures is becoming more common due to an increasing use of\nendovascular procedures. It is characterized by geometric shapes of nonscarring alopecia related to the area of radiation.We report\na case of a 46-year-old man presenting with asymptomatic, sharply demarcated rectangular, nonscarring alopecic patch on the\noccipital scalp following cerebral angiography with fistula embolization under fluoroscopy. His presentations were compatible with\nradiation-induced alopecia. Herein, we also report a novel scalp dermoscopic finding of blue-grey dots in a target pattern around\nyellow dots and follicles, which we detected in the lesion of radiation-induced alopecia.
