Spleen - Sonography

Spleen is located in the left subcostal area. We examine it by patient lying on his back or on his right hip. The probe should be placed dorsolaterally parallel with intercostal spaces. The examination could be more transparent by exspiration.

 

Spleen sizes:

Length: under 11cm

Width: under 4cm

 

Spleen - sonography

Spleen in classic picture with marked diameters.

Above the diaphragm there is already the pleural cavity.

 

 

Spleen enlargement – Splenomegaly is found by many diseases (blood diseases, infections, portal hypertension and other). When there is a distinct splenomegaly found we should also check abdominal areas with possible lymph node enlargements (periaortal space, liver hilum etc.).

 

Splenomegaly - sonography

Splenomegaly - In this picture we can see the affinity between spleen and left kidney.

We can not measure just from such picture, but spleen is undoubtedly enlarged.

 

 

Spleen infarction –They look like hypoechogenic zones in spleen tissue. No blood flow into such parts can be confirmed by duplex sonography.

 

Spleen infarction - sonography

Spleen infarction - We can see a hypoechogenic bearing marked

with a white arrow. Duplex color sonography was used as well, there

is no color signal from the ischaemic area.

 

 

Spleen hematoma – It is important to diagnose or exclude them after suspected abdominal traumas. They look like hypoechogenic areas. Dorsal from upper (medial) pole of the spleen we have to check for fluid - blood (anechogenic).

 

Splenic hematoma - sonography

Spleen hematoma - In this picture we can see a massive

hematoma between the spleen and diaphragm.

 

Splenic injury - sonography

Spleen injury - Here we can see two hypoechogenic bodies in splenic tissue (possibly

hematomas) and a very important anechogenic area near upper pole of the spleen -

probably subcapsular blood. Such finding refers about damage of the spleen and about the

danger of intraabdominal haemmorhage.

 

 

Spleen hemangioma – They look like hyperechogenic bright areas. They can resemble calcifications.

 

Splenic hemangioma - sonography

Spleen hemangioma - Hyperechogenic bearing is marked by a circle.

 

 

Spleen cysts – They look like classic anechogenic regular round objects. They are less frequent than the liver cysts.
