A follow up radiographs of the left small finger distal phalanx in anteroposterior (a) and lateral (b) view obtained two years after the symptoms begun. Diaphyseal distal phalanx widening and a central radiolucent zone are observed. Magnetic resonance image of the left small finger in proton density fast spin echo sequence in coronal (c) and sagittal (d) plane. Signal hyperintensity in the area of the distal phalanx that correlate with soft-tissue oedema is observed. On the dorsal aspect of the affected phalanx, a hypointensive oval lesion with no signs of cortical destruction is observed. These findings resemble an osteoid osteoma or sequestrum. An image of hands radionuclide skeletal scintigraphy with Technetium 99 m-MDP report in two projections palmar (e) and dorsal (f). Increased radionuclide uptake in distal phalanx/interphalangeal joint of the affected finger is predominantly observed in the dorsal projection
