Abstract
Osteoid osteoma is infrequently localized to the hand. Initially the lesion causes unspecific symptoms, and the radiographic changes are discrete. Three cases were seen during a period of 5 years. Bone scintigraphy was a useful diagnostic tool, and CT facilitated the identification of the nidus. One of the lesions was a double nidus osteoid osteoma of the scaphoid bone. Only 12 instances of multifocal osteoid osteomas have been reported, none of which was localized to the carpal bones.
