case_images: (A, B) Images of the sagittal plane (T1-weighted image) showed thickened Achilles tendons with a high signal strip (white arrow).

case_images: Proton density-weighted (PDW) images showed that the corresponding regions still produced abnormal signals in a strip or grid (Figures 1-3).
case_images: (A, B) Images of the sagittal plane (proton density-weighted) showed thickened Achilles tendons with a high signal strip, anterior border protuberance (white arrow), with no abnormal signal close to the subcutaneous tissues.

case_images: Proton density-weighted (PDW) images showed that the corresponding regions still produced abnormal signals in a strip or grid (Figures 1-3).
case_images: (A, B) Images of the axial plane (proton density-weighted) showed thickened bilateral tendons and right peroneal longus tendon with high (grid) and low (nodules) signal (white arrow).

case_images: Proton density-weighted (PDW) images showed that the corresponding regions still produced abnormal signals in a strip or grid (Figures 1-3).
case_images: (A, B) Images of ultrasonography showed thickened bilateral tendons and inhomogeneous echo. Continuity of bilateral tendons was acceptable.

case_images: The anteroposterior diameters of the left and right Achilles tendons were approximately 1.4 and 1.1 cm, respectively (Figure 4A and B).
case_images: Pathologic examination of excised tissue indicated the presence of foam cells, gouty crystals, a large number of macrophages, and other inflammatory cells with proliferation of tendon sheath fibers. (HEx10) Hematoxylin and Eosin Stain.

case_images: Combined with laboratory tests of hyperlipidemia and hyperuricemia, a diagnosis of xanthoma combined with gout infiltration of the Achilles tendon was made (Figure 5A and B).
