Intraosseous lipoma: 64-year-old male presents for follow-up of an incidentally discovered calcaneal intraosseous lipoma. Axial (a) and sagittal (b) non-contrast CT images demonstrate well-circumscribed lesion in the central calcaneus with thin sclerotic rim and central fat attenuation. Central thick rim of dystrophic calcification produces a classic “bull’s-eye” appearance related to cystic degeneration. Corresponding sagittal T1W (c) and T1W FS post-gadolinium (d) show the predominately fat signal calcaneal lesion with a central region of low T1 signal intensity compatible with cystic change and calcification. Minimal enhancement of the cystic portion of the lesion is present.
