Purpose:
To evaluate treatment of osteoid osteoma with computed tomography (CT)-guided percutaneous excision and immediate follow-up scintigraphy.
Materials And Methods:
Sixteen consecutive adolescent and adult patients underwent CT-guided percutaneous excision of a nidus with 14-gauge biopsy cutting needles, with local anesthesia. After the presence of nidus was confirmed at immediate follow-up scintigraphy, curettage of the bored cavity was performed to remove any residual fragments of the nidus. Scintigraphic and histologic findings were correlated.
Results:
The nidus was removed successfully in 14 of the 16 patients, with no complications (mean follow-up, 15 months; range, 3-25 months). In five of the 14 patients, immediate follow-up scintigraphy showed incomplete resection of the nidus and immediate second resection was successful. Surgical resection was necessary in two of the 16 patients.
Conclusion:
CT-guided percutaneous excision with immediate follow-up scintigraphy was safe and effective for localization and removal of osteoid osteoma in outpatients.
