Rare disorder causes bleeding on brain of 3-year-old girl

A neurosurgeon used a minimally invasive technique to repair an extremely rare blood vessel problem that caused bleeding on the brain of a three-year-old girl. The bleeding on her brain was caused by a complex and potentially devastating condition that is almost never seen in children. There are only a handful of descriptions in the medical literature. The surgery used to treat the girl used an endovascular techniques that use catheters rather than scalpels.
