case_images: fig1-2050313X211027094
case_images: Radiographs showed a calcaneal tuberosity osteolytic lesion with marginal sclerosis and no associated periosteal reaction (Figure 1).
case_images: Sagittal (a) and axial (b) T2-weighted MRI showing a 3.2 cm x 3.0 cm x 2.8 cm
  infiltrative hyperintense lesion with geographic margins. Erosion of the
  posterolateral cortex and significant local edema. (c). Sagittal T1-weighted
  MRI.

case_images: Posterolateral cortex erosion and significant bone and soft tissue edema were also observed (Figure 2).
case_images: (a) Gross specimens showing a soft, gray, mucoid, and gelatinous mass
  associated with purulent secretion. (b) Cavitary defect after complete

case_images: fig3-2050313X211027094
case_images: Soft tissue found inside the cavitary was a soft, gray, mucoid, and gelatinous mass associated with purulent secretion (Figure 3).
case_images: (a) The histologic specimens showed the appearance of Cryptococcus
  neoformans into the cytoplasm of macrophages (arrow),
  hematoxylin and eosin staining (a) (x400), and periodic acid-Schiff (PAS)
  staining (inset) (x400) (b).

case_images: fig4-2050313X211027094
case_images: Cryptococcus neoformans was histologically found as spherical or yeast-like organisms within the cytoplasm of macrophages, and no granulomas were seen (Figure 4).
case_images: (a) Clinical image showing complete healed lesion. (b) Postoperative lateral
  radiograph at 1-year follow-up.

case_images: fig5-2050313X211027094
case_images: The pain had progressively reduced at 2-year follow-up, and the patient was completely recovered and walking normally (Figure 5).
case_images: Sagittal (a) and axial (b) T2-weighted MRI showing a slight reduction of the
  hyperintense lesion.
