Figure 2 Preoperative imaging examination. A: X-ray; A-C: Left superior pubic branch - irregular pubic comb bone; D: CT; D-F: Partial bone absorption of the upper part of the left femur; bone destruction of the left acetabulum; swelling and unclear layers of soft tissue shadows in the upper part of the left thigh and around the hip joint; multiple cystic lesions in the upper part of the left thigh, with multiple cystic necrosis areas in the lesions, of which the posterior subcutaneous necrosis area is a long strip from the subcutaneous buttock to the lower back; G: MRI; G-I: The left upper femur and left hip joint have abnormal bone, with multiple necrosis sites around the hip joint and soft tissue of the left thigh as the main cystic disease.
