    Role of radiologic imaging in management planning of giant cell tumor of bone (1984)

    Notes: Abstract The radiologic studies of 24 patients with giant cell tumors were evaluated with respect to their ability to determine tumor extent and to influence management. Computed tomography (CT) was the most accurate method for detecting soft tissue tumor extension, and conventional tomography was the best technique for evaluating penetration of subarticular cortical bone. Detection of these findings led to performance of en bloc tumor resection rather than curettage and grafting in patients with lower extremity tumors. Arthrotomography was helpful in some instances in detecting cartilage and joint invasion by tumor, joint invasion being an indication for extra-articular rather than transarticular tumor resection. Scintigraphy was not as accurate as conventional tomography or CT in determining intraosseous tumor extent because of increased tracer, uptake beyond the true tumor limits in several cases. Angiography has been largely replaced by CT in evaluating giant cell tumors.

    The computed tomographic findings of popliteal cysts (1983)
    Springer
    Skeletal radiology 10 (1983), S. 26-29 
    Details
    ISSN: 1432-2161
    Keywords: Computed tomography ; Knee, synovial membrane ; Cyst popliteal
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract The computed tomographic (CT) findings of two popliteal cysts are presented, and the correlated anatomico-pathologic changes are discussed. The characteristic findings include thin, well-defined cyst wall, fluid density contents, central septum or septi, and medial popliteal location with mediocaudal extension. These findings, however, may vary due to herniation or rupture of the synovial membrane, gelatinous cyst contents, or metaplastic change of the cyst wall. Differential diagnoses include liposarcoma, popliteal aneurysm or hematoma, thrombophlebitis, xanthoma, fibrosarcoma, or other soft tissue tumors.

    Dynamic computed tomography scanning of benign bone lesions: Preliminary results (1983)
    Springer
    Skeletal radiology 9 (1983), S. 238-245 
    Details
    ISSN: 1432-2161
    Keywords: Dynamic CT scanning ; Benign bone lesions
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract The majority of benign bone lesions can be evaluated adequately using conventional radiologic techniques. However, it is not always possible to differentiate reliably between different types of benign bone lesions on the basis of plain film appearances alone. Dynamic computed tomography (CT) scanning provides a means for further characterizing such lesions by assessing their degree of vascularity. Thus, it may help in distinguishing an osteoid osteoma, which has a hypervascular nidus, from a Brodie's abscess, which is avascular. Dynamic CT scanning may also help in the differentiation between a fluid-containing simple bone cyst, which is avascular, and other solid or semi-solid benign bone lesions which show varying degrees of vascularity. However, because of the additional irradiation involved, dynamic CT scanning should be reserved for evaluation of selected patients with benign bone lesions in whom the plain film findings are not definitive and in whom the CT findings may have a significant influence on management.
