Size of the Spleen Copyright 2008 SIZE Length: = Transverse: = Antero-posterior: = Weight = Volume = Weight ranges from 80-300 g according to the content of blood Typically, the spleen measures about 12 cm in length, 7 cm in anteroposterior diameter, and 4 cm in thickness. The most practical and accurate assessment of splenic volume is the splenic index, which is the product of the length, width, and thickness of the spleen, each measured in centimeters, as measured on a CT scan. Splenic length is determined with CT scan by summing the number of contiguous slices on which the spleen is visible. The width is the longest splenic diameter that can be drawn on any transverse image. The thickness is measured at the level of the splenic hilum and is the distance between the inner and outer (peripheral) borders of the spleen. When the thicknesses of the anterior and posterior portions of the spleen differ significantly, two or three measurements are averaged. The splenic index is superior to subjective visual measurements and can assess splenomegaly more reliably than measurement of the extension of the spleen anterior to the aorta or below the rib cage on CT Grays “The size and weight of the spleen are liable to very extreme variations at different periods of life, in different individuals, and in the same individual under different conditions. In the adult it is usually about 12 cm. in length, 7 cm. in breadth, and 3 or 4 cm. in thickness, and weighs about 200 grams. At birth its weight, in proportion to the entire body, is almost equal to what is observed in the adult, being as 1 to 350; while in the adult it varies from 1 to 320 and 400. In old age the organ not only diminishes in weight, but decreases considerably in proportion to the entire body, being as 1 to 700. The size of the spleen is increased during and after digestion, and varies according to the state of nutrition of the body, being large in highly fed, and small in starved animals. In malarial fever it becomes much enlarged, weighing occasionally as much as 9 kilos.”
