Pseudo-ataxia due to Osteoid Osteoma

Juanette McKenzie, Curtis Oettel-Flaherty, Douglas Noel, Ruth H. Walker, Andrew K. Sobering


Background: Ataxia is diagnosed by typical features on examination suggestive of a cerebellar etiology and can invoke extensive diagnostic testing. Osteoid osteomas (OOs) are benign bone tumors of the lower limbs that occasionally present with focal neurological signs.

Case Report: A 3-year-old male presented with apparent progressive gait ataxia and non-specific leg pain. Initial imaging was unremarkable. However, 12 months later, a lesion was identified in the distal right femur, which was found to be an OO. The gait disorder and pain resolved after surgery.

Discussion: This case highlights the challenges of diagnosing a gait disorder in young children.
