(Top) Longitudinal oblique grayscale ultrasound shows the spleen from a posterolateral intercostal approach. The patient is positioned
in the right lateral decubitus position with examination during full expiration. Note that the tail of the pancreas can be imaged using
the spleen as an acoustic window. (Middle) Longitudinal oblique ultrasound shows the spleen and its relationship to the upper pole of
the left kidney with the transducer placed parallel to the intercostal space. (Bottom) Longitudinal oblique grayscale ultrasound of a
splenule (accessory spleen) is shown. Splenules are rounded, well-defined masses commonly found (10-30% of population) in or near the
splenic hilum. They are homogeneous and isoechoic to the splenic parenchyma.
