Adolescent / young adult with nocturnal pain relieved by NSAIDs, suspected osteoid osteoma

Q: What's the alternative imaging for adolescent / young adult with nocturnal pain relieved by nsaids, suspected osteoid osteoma when mri for marrow / soft tissue evaluation?

MRI — MRI affected region (iv contrast).

Recommended: CT or thin-slice X-ray (lucent nidus with surrounding sclerosis) is the preferred imaging study for adolescent / young adult with nocturnal pain relieved by nsaids, suspected osteoid osteoma. Benign bone lesion in adolescents and young adults.

Recommended study

CT or thin-slice X-ray (lucent nidus with surrounding sclerosis)

CT No contrast Preferred Musculoskeletal Outpatient Reviewed 2026-05

Benign bone lesion in adolescents and young adults. < 2 cm nidus with reactive sclerosis. Common in long-bone diaphysis, posterior elements of spine.

Watch-outs

Painful scoliosis in adolescents

Painful scoliosis = osteoid osteoma until proven otherwise; image the spine carefully.

Pearls

Pain worse at night, relieved by NSAIDs (prostaglandin-driven).
Radiofrequency ablation under CT guidance is curative.
Osteoblastoma is similar histology but > 2 cm, may behave more aggressively.
