Pita the Sea Turtle

I think it was in 2001 that a television special called Hopkins 24/7 aired. It was about Johns Hopkins hospital. In one episode they showed a sea turtle named Pita from the National Aquarium getting a CT scan and diagnosis for some ailment. I can neither remember nor find what that ailment was. I seem to remember that the turtle had ingested a rubber ball but that may or may not be accurate. Does anyone know for sure?
