    Castleman disease mimicking an aggressive retroperitoneal neoplasm (1994)
    Springer
    Abdominal imaging 19 (1994), S. 342-344

    ISSN: 1432-0509
    Keywords: Castleman disease ; Retroperitoneum ; MR imaging

    Topics: Medicine
    Notes: Abstract A case of Castleman disease of the retroperitoneum in a 26-year-old woman is presented. Sonography, computed tomography, and magnetic resonance imaging demonstrated a large retroperitoneal mass with somewhat heterogeneous imaging characteristics. Although a definitive preoperative diagnosis was not possible, magnetic resonance imaging was useful in delineating the extent of the tumor and defining the characteristics of surrounding soft tissues.

    Reliability of pedicle screw assessment utilizing plain radiographs versus CT reconstruction (1997)
    Springer
    European spine journal 6 (1997), S. 406-410 
    Details
    ISSN: 1432-0932
    Keywords: Pedicle screw ; Placement ; Accuracy ; Plain radiographs ; CT reconstruction

    Topics: Medicine
    Notes: Abstract The position of 119 pedicle screws was assessed on plain antero-posterior and lateral radiographs taken immediately post-operatively and at 3 months' follow-up. The readings of five independent observers were compared with the “gold standard” of CT reconstructions. The position of only 41 % of implants (range 14%–56%) was assessed correctly on the plain radiographs (47% on follow-up films). Two-thirds of CT-detectable perforations were missed. As shown with perforations of the anterior cortex, delectability increased significantly with magnitude of perforation. No specifically difficult anatomic level or direction of malplacement could be identified. Interobserver variation was considerable. Plain radiographs were shown to be of limited use in assessing the position of pedicle screws.
