-
White spots on a bone scan, also called cold spots, are evidence of abnormal bone metabolism, according to the Mayo Clinic. These tests do not detect the cause of the bone abnormalities.
Possibilities
Fracture, bone cancer and arthritis can cause bone metabolism abnormalities. Paget's disease of bone or fibrous dysplasia are other possible causes.
Follow-Up Tests
Further X-rays or a CAT scan can be performed to attempt to determine the cause of white spots. MRI imaging tests also can be used.
Paget's Disease
Paget's disease of bone distorts how bones break down and rebuild themselves, which can lead to fragile bones.
Fibrous Dysplasia
Fibrous dysplasia is characterized by the build-up of scar-like tissue in the place of bone. Treatment focuses on symptoms, which include fractures.
Bone Cancer
Bone cancer that begins in the bone is rare and most commonly affects the legs and arms.
