[Computed tomography of primary bone tumors in children]

The diagnostic value of CT examination in 21 children with 14 malignant and 7 benign bone neoplasias was evaluated. CT contributed in 72%; mainly in malignant conditions it was superior to other diagnostic techniques and demonstrated the exact intra- as well as the extraosseous extension. The cross sectional display facilitated evaluation of complex anatomic structures. Monitoring the treatment was easily performed by CT follow-up studies. However, 28% of all the examinations were not contributary, this group mainly including benign lesions.
