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

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.

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.

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.
