Purpose: Spleen is enlarged in a variety of clinical conditions including
infectious, infiltrative, immunologicand malignant states. Evaluation
of splenic size is important in every physical examination of the abdomen by a
physician. Determination of its size by palpation can be extremely inaccurate
because spleen is never palpable till it is enlarged 2 to 3 times its own size.
The accurate diagnosis of splenic enlargement is a matter of considerable importance
as it is a useful guide for arriving at a diagnosis of the disease. It is
therefore of utmost importance to resort to a mechanism that will give us an
accurate estimation of the size of spleen. Aim of this work wasto determine the normal
range of spleen dimensions in average adult Saudi Arabian population and
compare it with the published data. Methods: CT scans of 34 adult patients (male
and female) aged between 20 - 70 years, having no splenic disorders, were
collected from department of radio-diagnosis King Khalid Hospital Al-Kharj,KSA. Splenic
volume was measured by two methods—by volumetric software and the prolate
ellipsoid formula. Results: The
average splenic volume of all subjects was 161.42 ± 54.91 cm3 with a
range of 106 -319
