CT Atlas of Pediatric Retroperitoneal Spaces

Abstract

Abstract Imaging evaluation of the pediatric retroperitoneal spaces is complicated by complex 3D anatomy. While hard copy atlases of the retroperitoneal spaces exist, these often show only a few selected images of relevant anatomical structures. To facilitate understanding of the imaging anatomy of the retroperitoneal spaces, we constructed an online, large data-set, digital computed tomography (CT) atlas. The atlas demonstrates the normal appearance of the retroperitoneal spaces and incorporates color shading to illustrate the anterior pararenal, perirenal, and posterior pararenal spaces, and relevant fascial planes. In addition, we assembled a teaching file of CT cases comprised of entire imaging exams that show a variety of congenital, infectious, neoplastic, and inflammatory pathologies. The atlas of the retroperitoneum uses color shading and annotations to highlight normal anatomical structures. The teaching file cases are annotated as well.
