Studysummary This case report describes a 7-year-old girl who developed radiation-induced alopecia after a neurointerventional procedure, with dermoscopy revealing specific hair and scalp patterns that helped diagnose this rare complication. The findings highlight the importance of dermoscopy in distinguishing RIA from other alopecic disorders in children.

A 7-year-old girl developed a square-shaped alopecic patch on her occipital scalp 18 days after intracranial vascular malformation embolization, attributed to radiation-induced alopecia (RIA). Dermoscopic examination showed black dots, yellow dots, Pohl-Pinkus constrictions, tapered hairs, flame hairs, and upright regrowing hairs, confirming RIA due to the match with the radiation exposure field. The presence of Pohl-Pinkus constrictions and tapered hairs indicates a dystrophic anagen response, suggesting less severe follicular damage and potential for hair regrowth. This case highlights dermoscopy's role in distinguishing RIA from other alopecic conditions in pediatric neurointerventional patients.
