The mass has smooth surface and solid consistency (Figure 1).
Case 1. (a) Bone survey radiographic examination of the cranium. (b) Multiple lytic lesion with well-defined border in the cranium. Arrow shows bone resorption activity in lower alveolar area.

Bone survey showed the diffused decreasing bone density, fractured right clavicle, multiple lytic lesions among the cranium, humerus, clavicle, iliac, and pubic bone (Figure 2 and Figure 3).
Case 1. Bone survey radiographic examination of the (a) pelvis showing multiple lytic lesion along the bilateral iliac bone and pubic bone and the (b) humerus and clavicle showing multiple lytic lesion along the lateral edge of the humerus. Pathologic fractures of the distal part of the left clavicle are observed, increased bone resorption among the bilateral clavicle.

Bone survey showed the diffused decreasing bone density, fractured right clavicle, multiple lytic lesions among the cranium, humerus, clavicle, iliac, and pubic bone (Figure 2 and Figure 3).
Case 1. Paranasal CT scan. Decreased diffuse with ground glass appearance among the cranium, facial, and cervicothoracic bones. Multiple lytic lesion in the maxillary bones.

Paranasal sinus CT showed a decreased bone density in the cranial, facial, and cervicothoracic bones; lytic lesion in the maxilla bone extended to the palatum durum and shifted the tongue inferiorly, with the measurement of 5.2 x 4.6 x 3.7 cm (Figure 4).

The physical examination showed facial asymmetry with mass in the palatum durum, measured 4 x 3 cm in size (Figure 5).
Case 2. Bone radiographic examination of the skull showing multiple lytic lesion among the calvaria, decreased diffuse bone density among the calvaria, and multiple lytic lesion in the calvaria, maxilla, and mandible. Salt and pepper appearance in the calvaria.

X-ray of the maxilla and mandible showed diffused decreasing bone density and multiple lytic lesion, which suggest metabolic bone disease or renal osteodystrophy or hyperparathyroidism (Figure 6).
Case 2. Head CT scan showing diffused hyperostosis with multiple lytic lesion among the bones of maxilla, mandible, and the skull.

Facial CT with contrast showed diffuse hyperostosis, lytic lesion in the mandible bone, maxillary bone, cranium, and multiple calcification in the soft tissue which is compatible with osteorenal dystrophy (Figure 7).
