Abstract Objective: To review the reliability of CT and MRI features of lipoma and lipoblastoma. Materials and Methods: CT and MRI of 35 cases of lipoma and 10 cases of lipoblastoma were retrospectively reviewed. Images were assessed for adipose tissue content, nonadipose component, presence of septa, the thickness of septa, presence of calcification and the growth pattern. Results: Features that suggest lipoblastoma include presence of thick septa, presence of nodular and or globular or nonadipose masslike areas, and decreased percentage of fat composition. Conclusion: CT and MRI features are reliable to distinguish lipoma and lipoblastoma.
