


Normal size – 12 cm length , 7 cm width
(radionuclide scan)
-13cm craniocaudal diamtr (USG)
weight- < 250gm
Located along- 9th, 10th,11th ribs mid-axillary
Spleen should be twice the size to be PALPABLE
Palpable spleens are not always ABNORMAL
3% normal population has palpable spleen

EXAMINATION OF SPLEEN
