COLUMBUS, Ohio -- The parents of a 13-year-old girl who died after being hit in the head with a puck at an NHL game almost a year ago sued the hospital where she was treated.

The suit contends doctors failed to see the extent of Brittanie Cecil's brain damage in time to save her.

The lawsuit by Robert Cecil and Jody Lynn Sergent was filed Feb. 28. It names Children's Hospital, Drs. Scott W. Elton and Leslie Jean-Regis Acakpo-Satchivi, along with medical staff members who worked on Brittanie. The suit did not specify a maximum amount in damages.

Children's spokesman Amy Nance said Thursday she could not comment.

Acakpo-Satchivi had no comment, said spokeswoman Emily Caldwell of Ohio State University Medical Center, where the doctor now works. A message left at Elton's office was not immediately returned.

Brittanie's family settled last month with the NHL, the Blue Jackets and Espen Knutsen, the Blue Jackets player who hit the puck that struck Brittanie. Details of the settlement have not been released.

Brittanie died two days after a puck struck her as she watched the March 16 game in Nationwide Arena between the Columbus Blue Jackets and Calgary Flames. After her death, the NHL required every team to hang netting to prevent injuries from pucks.

Brittanie was attending the game while visiting her father. He had given her the ticket to celebrate her 14th birthday that week.

The suit says doctors didn't see the extent of her brain damage in the first of two brain scans and did not do the second scan in time to combat fluid buildup in her head.

The first brain scan was taken within two hours of Brittanie arriving at the hospital after she had a seizure while her forehead wound was being stitched. The second scan was on the morning of March 18 after her pulse had stopped, the suit states. She was declared brain dead that night.

Hospital staff members treated Brittanie's symptoms but failed to quickly diagnose the underlying condition, said Michael Wright, one of three lawyers representing the parents.
