Osteoid osteoma: resection with CT guidance.
BACKGROUND
Osteoid osteoma is a benign bone lesion characterized by nocturnal pain mostly, which may be relieved by non-steroidal prostaglandin inhibitors. Treatment by complete resection of the nidus immediately relieves the pain. Intraoperative location of the nidus may be difficult, and extensive bone resection may be necessary to ensure complete excision. Few studies have described resection of osteoid osteoma under CT guidance, and little attention has been given to lesions near the neurovascular bundle.


OBJECTIVE
To report our results of osteoid osteoma resection under CT guidance, with specific attention to lesions lying near the neural structure.


METHODS
Nine patients with suspected osteoid osteoma underwent resection with a 6.8 mm core drill under CT guidance.


RESULTS
Histologic confirmation was obtained in seven patients, while in two there was no evidence of the nidus in the excised bone material. All nine reported complete pain relief immediately after the surgery. Postoperative CT scan showed complete removal of the osteoid osteoma.


CONCLUSIONS
Removal of osteoid osteoma under CT guidance is simple, safe and allows complete removal of the nidus with low morbidity.
