Osteoid osteoma causing chronic hip pain in a child

Area of Science:

• Orthopedics
• Pediatric Oncology

Background:

• Osteoid osteoma is a common benign bone tumor in young individuals.
• Symptoms like nocturnal pain relieved by analgesics are typical.
• Periarticular lesions can mimic arthritis, complicating diagnosis.

Purpose of the Study:

• To report a case of osteoid osteoma in a pediatric patient presenting with hip pain and limp.
• To highlight diagnostic challenges and successful treatment outcomes.

Main Methods:

• Case report of a 7-year-old girl with persistent hip pain.
• Diagnostic workup included bone scan and computerized tomography (CT).
• Treatment involved percutaneous excision under CT guidance.

Main Results:

• Initial bone scan showed increased activity in the right hip.
• Routine X-rays were normal, delaying diagnosis.
• CT confirmed osteoid osteoma of the right femoral neck.
• Percutaneous excision provided successful treatment.

Conclusions:

• Osteoid osteoma should be considered in pediatric hip pain, even with normal X-rays.
• CT is crucial for diagnosing intraosseous lesions like osteoid osteoma.
• Minimally invasive techniques like percutaneous excision offer effective treatment.
