Computed Tomography of the Retroperitoneum: An Anatomical by Michiel A.M. Feldberg

By Michiel A.M. Feldberg

With the arrival of CT we entered a brand new quarter of radiological imaging. constructions which hardly if ever have been visible grew to become obvious. In no a part of the physique was once the impression of CT as profound because it was once within the retroperitoneum. within the pre-CT zone this area of the physique couldn't be at once studied and in simple terms whilst gross abnormalities have been current might they be favored. the easiest lets do used to be to attempt to spot a suspected strategy by way of learning its influence on surrounding organs whose place could have been plagued by the expansion. Urography, barium reviews or angiography have been hired within the wish that edition within the place of the vessels, ureter or bowel could lead us to the right kind analysis. With computed tomography all this replaced. sleek scanners, on hand to all this present day, let us to understand information undreamed of simply few years in the past. The abundance of fats during this area is helping to obviously express even the smallest of buildings. now we have the facility to acknowledge small vessels, lymph nodes and fascial planes. We had a device which accepted us to check buildings which hitherto have been in basic terms obvious by way of the anatomist or in the course of surgical dissection.

Where fluid is present in Morison's pouch on the right side and splenorenal recess on the left (black arrows) , is the anterior renal fascia not discernable from peritoneum (white arrows). It is only possible where anterior pararenal fat (1) is present in b. (black-white arrows). The posterior renal fasciae are thickened in b. (arrow-heads) in this case of pancreatitis. FHC: hepatic flexure of colon; LS; lesser sac; M; pancreatic mass. Figure 2-22c. Pancreatic abscess in anterior pararenal space (1).

Fluid in left perirenal space (2) with thickened anterior renal fascia (arrowheads), fibrous strands (open arrows) and diaphragmatic pillars (closed arrows). The posterior renal fascia is not discernable from diaphragmatic pillars. 44 2-30b 2-30c 2-30d Medial extent of posterior renal fascia Figure 2-30a. Posterior pararenal fluid (3) on the right side at bare area of liver. The posterior renal fascia is thickened and its very cranial course behind the right kidney (RK) extending to the diaphragmatic pillar is visible (arrows).

Technical improvement in the CT-scanners such as direct magnifications allows for visualization of the renal fascia in many instances on transverse scans and occasionally on direct coronal and sagittal cuts. When one sees a curvilinear structure on several CT slices conforming with one of the anatomical concepts it is labeled the renal fascia. We may not have the same evidence as the anatomist can give in the dissecting room since we are dealing with a 23 2-12 Figure 2-12. View of gross specimen of transverse cut right kidney with spread out fascia of Gerota (G), stripped off fibrous capsule (FG), lobulated perirenal fat (PRF) and fibrous strands (FS).
