Osteoid Osteoma

Osteoid osteomas are benign bone lesions with classic characteristics on plain film, MRI and CT. They are also a very common exam case and are worth rehearsing in a slick way.

The clinical presentation of osteoid osteomas is also rather classic and should be mentioned to the examiner. Young patients experience night pain at the site of the lesion, and it can be relieved by taking aspirin. It must be one of the only painful conditions that responds to aspirin!

Treatment options rarely include surgical excision nowadays. Referral to a specialist bone tumour centre is recommended and a sequence of biopsy + radiofrequency ablation is common. Most of the time the diagnosis is so clear that both take place in a single procedure, with an initial biopsy being taken followed by ablation through the same access tract.
