Radiological evaluation revealed bilateral ossified mass lying anterior to the hip joint originating from the anterior superior margin of the acetabulum and extending to the lesser trochanter (Figure 1).   A 3-dimensional computerized tomography (3D-CT) scan revealed bilateral well-defined masses (Figure 2).

We could then find the 10 cm long bony mass and carefully isolated it with minimal bleeding, osteotomized at the proximal end, stripped from the adherent soft tissue, and removed (Figure 3).
