Abstract

Objective To study the computed tomography (CT) manifestations of normal left posterior pararenal space (LPPrS). Methods (1) One cadaver was perfused with latex into the left anterior pararenal space. The anatomical characteristics of the bilateral posterior pararenal space was observed and the diffusion of perfusion agent in the LPPrS was recorded. (2) The abdominal CT data of 50 normal adult were analyzed to observe the morphology and fat thickness of LPPrS, the vascular display of LPPrS and its relationship with the left posterior renal fascia. The maximal fat thickness of LPPrS at the level of left renal vein and the subcutaneous fat area at the level of the second lumbar vertebra were measured, and their correlation was analyzed. Results (1) After entering into the interfacial planes of the left posterior renal fascia, the axial tomography perfusion agent spread along the fiber separation of LPPrS. The posterior pararenal space was menisus in shape with multiple vessels. (2) On the axial CT images, multiple vascular shadows were detected in the LPPrS and mainly located in the lateral and posterior left kidney. The blood vessels passed through the left posterior renal fascia. CT images showed slender separation in the LPPrS. The average maximal fat thickness at the left renal vein level and the subcutaneous fat area at the second lumbar vertebra level were 0.77 cm and 112.37 cm2. The relationship of them was positive (r=0.283, P<0.05). Conclusions The LPPrS has its own anatomical features. Paying attention to the CT manifestation of the LPPrS is helpful to the imaging diagnosis and treatment of LPPrS lesions and adjacent organs.
