The bone forming, osteoblastic, tumors including osteoma, osteoid osteoma, and osteoblastoma are slow growing benign lesions, forming well differentiated mature bone tissue with a structure of lamellar bone. The diagnosis of these tumors is based on histopathological features correlated with clinical and radiological findings. Although they may present different clinical circumstances, imaging features of these lesions are usually characteristic and suggest that there is a certain diagnosis. However, osteosarcoma, another osteoblastic but malignant tumor, should be considered in the differential diagnosis of all of the three lesions. Osteoma is a well-defined and homogeneous lesion, often caused by bone surface of the paranasal sinuses and the cranium. The lesion is usually detected incidentally and can cause symptoms such as sinusitis, headaches and diplopia depending on the size and the location. Long bone involvement can show itself with swelling or local pain. Osteoid osteoma is a painful lesion, usually affects long bone diaphysis in young patients. A small radiolucent nidus surrounding the dense sclerosis is seen in the direct radiograph. Osteoblastoma is a rare tumor, often holds the spine and long bones, histologically similar to osteoid osteoma but it has more aggressive behavior. Osteoblastoma may present as different clinical presentation and radiological appearance. In this review the clinical and radiological features of benign bone forming tumors and the current treatment modalities are presented.
