Takayasu arteritis with a ruptured intracranial aneurysm in a pediatric patient: illustrative case.

BACKGROUND

Takayasu arteritis (TA) is a rare, chronic vasculitis primarily affecting the aorta and its major branches. Although intracranial aneurysms associated with TA have been documented, rupture in pediatric patients is exceedingly rare.

OBSERVATIONS: The authors report the case of a 14-year-old girl with TA who developed a ruptured cerebral aneurysm. She was successfully treated with endovascular coil embolization and remained neurologically intact at follow-up.

LESSONS: This case highlights the importance of recognizing cerebrovascular complications in TA and demonstrates the feasibility of endovascular management in pediatric patients. https://thejns.org/doi/10.3171/CASE25166.
