Achilles tendon xanthoma in cerebrotendinous xanthomatosis (MRI)

(A) Sagittal T1-weighted, (B) proton density, and (C) STIR images show fusiform enlargement of the right Achilles tendon (arrows); the xanthoma is relatively isointense compared to muscle. (D) An axial proton density image shows diffuse fat infiltration with low-intensity tendon bundles interspersed within (arrows). Note: STIR = short tau inversion recovery.
