Below: Coronal CT scan shows a radiolucent nidus (black arrow) with surrounding bony sclerosis and cortical thickening (white arrow)
What are these arrows pointing to? Tumor?
Osteoid osteoma
Side: randomly interconnected trabeculae of woven bone, prominently rimmed by a single cell layer of osteoblasts
Bottom: The stroma surrounding the neoplastic bone consists of loose connective tissue containing dilated and congested capillaries

Osteoblastoma
Similar to an osteoid osteoma, but is larger (>2cm), arises in the vertebrae, presents with bone pain that doesn’t respond to aspirin.
60% female, children and young adults
Comprised of anastomosing trabeculae of osteoid and woven bone rimmed by osteoblasts
