A 26-year-old male presented for magnetic resonance (MR) examination of the ankle for chronic ankle pain. MR images of the ankle revealed marked intraosseous bone marrow hyperintensity involving the talus on the fast inversion recovery sequence. In addition, at the anteromedial margin of the posterior facet of the talus, a round, sclerotic lesion was present with an associated mild to moderate reactive synovitis in the subtalar joint. Findings were consistent with an osteoid osteoma.
