Osseous lipoma: CT appearance.
Characteristic radiographic and computed-tomographic (CT) features of seven cases of osseous lipoma are reported: six with medullary and one with parosteal locations. Radiological diagnosis of this lesion is discussed, with emphasis on potential pitfalls in interpretation of CT scans. Although the presence of fat-equivalent density on scans is highly suggestive of osseous lipoma, comparable attenuation is documented in cases of chronic osteomyelitis and postnecrotic subchondral excavation.
