Radiograph of the pelvis in anteroposterior view, showing circumferential osteolytic lesions in the wing of the right iliac, of approximately 3 cm in diameter, with well-defined borders (A). Tomography with three-dimensional reconstruction, in which a lesion affecting the posterior cortical bone of the wing of the right iliac is observed (B).

A circumferential osteolytic lesion in the wing of the right iliac, of approximately 3 cm in diameter, with well-defined edges, was observed (Fig. 1A). A lesion affecting the posterior cortical bone of the wing of the right iliac could be seen (Fig. 1B).
Tomographic slices in coronal view for a bone window (A) and in axial view for a soft-tissue window (B), showing that the lesion extends through the medullary tissue, from the anteromedial to the posterolateral region of the right iliac bone. In this region, there was fracturing of the cortical bone, of osteolytic and insufflative nature.

A coronal slice for a bone window (Fig. 2A) and an axial slice for a soft-tissue window (Fig. 2B) showed that the lesion extended through the medullary tissue, from the anteromedial to the posterolateral region of the right iliac bone.
Bone scintigraphy with technetium, which did not show the lesion (A and B), thus suggesting that it was of benign nature.

Bone scintigraphy with technetium was performed and did not show the lesion (Fig. 3A and B), which suggested that the lesion was of benign nature.
Magnetic resonance imaging of the pelvis, in which the T1 coronal image showed a lesion with hyposignal, without soft-tissue invasion (A), and in T2 (B) with hypersignal in the right iliac.

T1 coronal imaging showed a lesion with hyposignal, without invasion of soft tissues (Fig. 4A). T2 coronal imaging of the pelvis (Fig. 4B) showed a lesion with hypersignal in the right iliac.
