Retromesenteric Plane Fluid Collections

Retromesenteric plane fluid collections are well-defined planes anterior to the perirenal spaces and posterior to the pancreas, duodenum, and right and left colonic compartments. Because of the presence of primitive roots of the dorsal mesenteries in the midline, communication across the midline is only possible where fusion planes cross the midline, as especially occurs behind the horizontal portion of the duodenum, just inferior to the superior mesenteric artery (Figs. 8-114 and 8-116). Cranially, the extension of the retromesenteric fluid is usually to the bare area of the stomach (Fig. 8113) and dorsally around the lateral border of the peri-renal space into the retrorenal space and/or the latero-conal space (Figs. 8-112, 8-113, 8-115).
