Osteoid osteoma, a benign bone lesion, rarely affects small bones like phalanges, posing diagnostic challenges. Radiofrequency ablation effectively treated a phalangeal osteoid osteoma, relieving pain.
Area of Science:
- Orthopedic Surgery
- Musculoskeletal Radiology
Background:
- Osteoid osteoma is a common benign osteoblastic bone lesion, typically affecting long bone cortices.
- Phalangeal involvement is rare, presenting a diagnostic challenge due to its location in cancellous bone.
Observation:
- A case report details a 26-year-old with chronic great toe pain.
- Initial radiographs and MRI were inconclusive; a single-photon emission computerized tomography scan identified the nidus.
- The patient underwent successful radiofrequency ablation for the phalangeal osteoid osteoma.
Findings:
- Osteoid osteoma in phalanges is uncommon and can evade detection by standard imaging modalities.
- Single-photon emission computerized tomography is crucial for diagnosing phalangeal osteoid osteoma when other methods fail.
Implications:
- Early diagnosis and treatment of phalangeal osteoid osteoma lead to excellent prognoses.
- Consider osteoid osteoma in the differential diagnosis for chronic foot pain, especially with nocturnal exacerbation.
