Magnetic resonance imaging (MRI) scans for osteoid osteoma could be misleading and
can be misinterpreted as tuberculosis, especially when used as the principal modality
of investigation. We retrospectively reviewed cases presenting to our institute for
second opinion and selected six cases that were referred to our institute with a provisional
diagnosis of tubercular arthritis or osteomyelitis and were identified to have osteoid
osteoma. We reviewed the literature on typical and atypical clinical and radiological
presentations of osteoid osteoma depending upon their location and present radiological
features on MRI that should alert the radiologists toward a correct diagnosis.
