Maya, a ballroom dancer, presents with abdominal pain after a fall during dancing. She develops a retroperitoneal bleed requiring emergency surgery. Her inability to clot properly leads to discovery of her underlying bleeding disorder.
Maya is diagnosed with Bernard-Soulier syndrome, a rare inherited bleeding disorder characterized by abnormally large platelets and impaired blood clotting. This condition caused her near-fatal bleeding during surgery and created blood-filled pseudotumors that destroyed her femur bone.
Blood-filled pseudotumors caused by Maya's bleeding disorder ate away at her femur bone, requiring a decision between risky total femur replacement surgery or amputation. Leo ultimately chooses amputation to save her life despite her wishes to save her dancing career.
