Abstract
BACKGROUND

Osteofibrous dysplasia (OFD) is a developmental skeletal disorder, and cases with a giant affected area in the pelvis are rare.

CASE SUMMARY

In this case report, a 48-year-old man presented with a large tumor in the right iliac region that turned out to be OFD. The patient had rebound tenderness in his right hip. After radiography examination, magnetic resonance imaging examinations and some physical examination, extensive bone destruction in the right ilium was confirmed. Moreover, changes in bone mineral density and peripheral cortical bone sclerosis with surrounding soft tissue swelling were observed. Thus, this patient was considered to have giant monostotic OFD of the ilium. The tumor-related area was removed completely by surgery, and the remaining cavity was filled by artificial bones from the opposite ilium. According to the results of follow-up, the patient had normal flexion and extension activities of the right hip joint, and there was no evidence of recurrence of the tumor.

CONCLUSION

Suture of iliopsoas and gluteus medius muscle following focus curettage and bone grafting is a promising and effective method to treat giant OFD of the ilium. It is a feasible way to fill a large cavity after removing a lesion like the one is this case.

Core tip: Osteofibrous dysplasia is a developmental skeletal disorder, and cases involving the pelvis with a large affected area are rare. This report is the first case, to our knowledge, of a 48-year-old man with a huge tumor in the right iliac that turned out to be osteofibrous dysplasia. With the assistance of computed tomography and magnetic resonance imaging, the tumor was completely removed, and the left empty cavity was reasonably filled by pulling and suturing nearby muscles and using some artificial bone.
