[Osteoid osteoma of the coccyx: a case report].

The spine is a rare localization of osteoid osteoma and the coccyx even more exceptional. We report a case of osteoid osteoma of the coccyx in a young man who consulted for sacrococcygeal pain partially relieved with salicylates. Computed tomography of the region demonstrated a typical osteoid osteoma lesion. CT-guided localization enabled complete resection of the nidus as demonstrated by the CT of the operative specimen Pathology confirmed the diagnosis of osteoid osteoma. Outcome has been quite favorable at two years.
