Summary
Osteoid osteomas in the acetabulum are rare and difficult to diagnose, often presenting with chronic synovitis. Computed tomography (CT) is crucial for diagnosis, and surgical resection leads to excellent outcomes.
Area of Science:
- Orthopedic Surgery
- Oncology
- Radiology
Background:
- Osteoid osteoma is a benign bone tumor.
- Acetabular osteoid osteomas are rare, leading to diagnostic challenges.
Observation:
- Two cases of acetabular osteoid osteoma with severe chronic synovitis are presented.
- Clinical signs are nonspecific, delaying diagnosis.
Findings:
- Computed tomography (CT) scanning is the optimal diagnostic modality.
- Intraarticular surgical resection is effective.
- One case required bone grafting.
Implications:
- Early diagnosis and surgical management of acetabular osteoid osteoma can yield excellent results.
- Highlights the importance of advanced imaging in rare tumor presentations.
