Introduction:
Osteoid osteoma is a common benign osteoblastic lesion of the bone. Although it commonly affects the cortex of long bones, it rarely involves the cancellous portion of the small bones such as phalanges. The occurrence of osteoid osteoma in phalanges poses a diagnostic dilemma.
Case Report:
In our case report, we presented a 26-year-old patient with long-standing pain over the great toe. The radiographs and magnetic resonance imaging (MRI) were unable to diagnose the lesion, and a single-photon emission computerized tomography scan picked up the nidus. She underwent radiofrequency ablation and post-procedure she was relieved of her symptoms.
Conclusion:
Osteoid osteoma of the phalanges is uncommon, and at times, routine radiographs and MRIs might not point us to the correct diagnosis. As the prognosis is excellent after the treatment is instituted, osteoid osteoma should always be a differential in chronic foot pain with nocturnal predominance.
