EDUCATION EXHIBIT

Pediatric Presacral Masses1

Murat Kocaoglu, MD and Donald P. Frush, MD

1 From the Department of Radiology, Gulhane Military Medical School, Ankara, Turkey (M.K.); and Division of Pediatric Radiology, Department of Radiology, 1905 McGovern-Davison Children’s Health Center, Box 3808, Duke University Medical Center, Erwin Rd, Durham, NC 27710 (D.P.F.). Presented as an education exhibit at the 2004 RSNA Annual Meeting. Received April 25, 2005; revision requested May 26 and received July 20; accepted July 29. Both authors have no financial relationships to disclose. Address correspondence to D.P.F. (e-mail: frush943{at}mc.duke.edu).

Various types of masses may affect the presacral area in children. A presacral mass may be congenital or developmental or may arise from inflammation. The mass may have neural, vascular, lymphatic, or mesenchymal origins and may be primary (as in focal disease) or systemic (as in multifocal disease). Because the clinical manifestations of presacral masses are often nonspecific, imaging plays an important role in the detection and differentiation of these masses. Information obtained from imaging is also critical for management, especially for surgical planning. For these reasons, it is important that radiologists be familiar with the anatomy of the presacral region and with the imaging features of the various lesions that may occur in this region in children. For the accurate interpretation of findings, radiologists also must know the specific advantages and limitations of each of the imaging modalities used to evaluate this category of abnormalities.
