1. Accessory spleen (splenules)

4.2.1\ Scanning Method

The patient should be on fast for 8–12 h with a right lateral decubitus position; probe is put in the left ninth, tenth, or eleventh intercostal spaces.

4.2.2\ Section Structure

The accessory spleen occasionally is found near the hilum of the spleen in the longitudinal section of the spleen, as a hypoechoic nodule which is connected to the spleen and has the same echogenicity as the spleen.

4.2.3\ Measuring Method and Normal

The size of the accessory spleen is measured.

4.2.4\ Clinical application value

The accessory spleen (splenules) is congenital dysplasia. Its incidence is 10–30%. In most subjects, the accessory spleen is located at the hilum of the spleen and connects to it. A few locations include splenic blood vessels, greater omentum posterior, pancreatic tail, and greater omentum along the greater curvature stomach.

4.3.1\ Scanning Method

Patient should be on fast for 8–12 hours with a right lateral decubitus position; probe is put in the left ninth, tenth, or eleventh intercostal spaces.

4.3.2\ Section Structure

The short axis section of the spleen, left kidney, and pancreatic tail and the longitudinal section of the splenic vein and the left renal vein are shown in this plane.

4.3.3\ Clinical Application Value

The boundary of the spleen and left kidney should be understood, so that the position of the neoplasm in the left upper abdominal can be determined where them come from.
