Contrast-enhanced helical axial sections of 5 mm thickness were obtained through the bony pelvis, including both hip joints. A fracture of the anterior wall, posterior wall, and roof of the left acetabulum, along with the adjacent part of the left iliac bone, is noted. A fracture of the left superior and inferior pubic rami is noted. The rest of the visualized pelvic bones, lumbar sacral vertebrae, sacrum, and the visualized femoral head and neck show normal cortical outlines and trabecular patterns. Bilateral hip joint spaces are normal and symmetrical. The articular surfaces are smooth and congruent. There is no evidence of joint effusion. Both sacroiliac (SI) joints appear normal. The articular surfaces are smooth and congruent. There is no evidence of subchondral erosions, sclerosis, or joint irregularity. Surrounding muscle bundles and fascial planes appear normal.
