We report a case of 26-year-old woman with left breast cancer referred for 18F-NaF PET-CT. She is complaining of right thumb and wrist pain. Findings are negative for bone secondaries. Dedicated hands views are acquired on positron emission scanner which shows focal uptake at 1st carpometacarpcal and 2nd metacarpophalangeal joints. Findings are likely due to active arthritic changes due to repetitive strain injury caused by excess text messaging (textitis).
