title: [The percutaneous removal of osteoid osteomas via CT-guided drilling].
abstract: Osteoid osteomas were removed by CT-guided core drill excision of the nidus in 4 patients. All osteoid osteomas were located in the lower extremity and included cortical lesions in the femur (n = 2), and the tibia (n = 1) and one spongious lesion in the navicular bone of the foot. Nidus diameter ranged from 2 to 3 mm. The patients were discharged after the procedure same day or next day depending on the kind of anaesthesia performed. Follow-up periods ranged from 6 to 56 months and revealed no signs of recidivation. CT-guided core-drill excision of the nidus seems to be a very promising alternative to surgical procedures because of its high cost-effectiveness and minimal invasiveness.
