Accessory spleen.
An isoechoic mass is seen adjacent to the spleen
The diaphragm is also clearly identified in this image (arrow)
Splenomegaly.
Transverse image of an enlarged spleen in a patient with cirrhosis and portal hypertension.
There are multiple prominent blood vessels adjacent to the splenic hilum
Splenic cyst.
Splenic infarct.
often appear as wedge-shaped hypochoic areas within the spleen
Splenic hematoma.
An intraparenchymal hematoma (H) is seen as a solid-appearing mass within the spleen (S).
Splenic hemangioma.
Two small, echogenic masses representing hemangiomas are noted in this asymptomatic patient.
Lymphoma.
Transverse image of the spleen in a patient with Hodgkin lymphoma reveals a hypochoic mass (between calipers).
Color Doppler shows the splenic arterial system within the spleen
The splenic venous system is well demarcated with color Doppler
Color Doppler shows the dilated splenic vessels that may be seen with portal hypertension and varices
Patterns of splenomegaly.
A and B, The tip of the enlarged spleen covers the lower pole of the kidney.
C, The dilated splenic hilum is secondary to portal hypertension; with hepato-splenomegaly.
