Discuss the approach to the child with joint pain or arthritis 2. Recognize the diagnostic clues of the different arthropathies 3. Develop strategy for the diagnosis

Osteoid Oteoma 1. Osteoid osteoma is a common benign tumor of the bone that accounts for 2% to 3% of all primary bone neoplasms 2. Occurs in children and young adults, with age range of 5 and 20 years. Male > Female 3. The classical symptom is well-localized throbbing pain at night. Confusion can arise when the lesion is near a joint because it can mimic symptoms of arthritis or synovitis, thus leading to an incorrect diagnosis 4. The pain associated with osteoid osteoma is caused by the presence of abundant unmyelinated nerve fibers of the autonomic nervous system within the tumor nidus 5. Treatment is surgical, with en bloc excision of the tumor under Ct guidance
