Roentgen Anatomy of Distribution and Localization of Collections

The perirenal space on each side is distinctly defined by the cone of renal fascia (Figs. 8-117 through 8-119).

Selective opacification of this compartment in the cadaver permits identification of the preferential pathway of spread and the characteristic localizing features. This is shown in Figure 8-120. The space is surprisingly capacious, and distention yields a typical outline. The injection study demonstrates that the lower border of the distended cone of renal fascia presents a diagnostic silhouette, inferiorly convex, overlying the region of the iliac crest. Some acute traumatic episodes provide an in vivo model and confirm these investigational observations (Figs. 8-121 and 8-122). This outline is the hallmark of perirenal collections, and its identification, therefore, on plain films as well as on other studies (Fig. 8-123) serves reliably to localize a disease process immediately.

The significant criteria for the localization and distinction of collections within the perirenal space are outlined in Table 8-1 on page 360.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
