SpleenAnatomy
• The spleen is located in the left upper quadrant of the abdomen beneath the 9th to 11th
ribs. The costo-diaphragmatic recess of the left pleural cavity extends as far as the
inferior border of a normal spleen.
• The spleen is intimately related to the splenic flexure of the colon, the greater
curvature of the stomach, the left kidney, and the pancreatic tail.
