Ultrasound examination review: Spleen
splenic artery originates at the
celiac trunk
The spleen removes irregular cells from the bloodstream and retains them through a process called
culling
Hydatid cyst
cyst results from parasites infestation of an organ by a tapeworm
Most common sonographic appearance of a splenic hemangioma
echogenic
Epstein-barr infection
herpevirus that can lead to infectious mononucleosis
Most common cause of splenomegaly
portal hypertension
Splenic vein marks the
posterior aspect of the pancreatic body and tail
what is the systemic disease that results in the development of granulomas within the spleen and throughout body
sarcoidosis
Granulomas
small echogenic calcifications that result from inflammation of tissue in that area
white pulp
specialized lymphatic tissue within the spleen
Red pulp
specialized tissue within the spleen that performs phagocytic function
Most common place for accessory spleen
splenic hilum
An area within the spleen that has become necrotic because of lack of oxygen
splenic infarct
Diffuse involvement of lymphoma or leukemia of the spleen will often lead to
splenomegaly
sickle cell disease will often lead to
splenomegaly
The splenic artery marks the the
superior aspect of the pancreatic body and tail
Splenic vein joins with what structure posterior to the pancreatic neck to form the portal vein
superior mesenteric vein
sarcoidosis
systemic disease that results in the development of granulomas throught the body
Type of tissue within the spleen that is responsible for lymphatic function
white pulp
The spleen
- Largest lymphatic organ -The largest structure of the reticuloendothelial system -Primary objective is to filter the peripheral blood
Hemangioma
A benign tumor composed of blood vessels
A 25 yr old female patient presents to the u/s dept. for a complete abo sono. complaint of RLQ pain and nausea. RuQ abdomen appears normal. Small mass noted in splenic hilum. Mass appears isoechoic to spleen. What is this?
Accessory spleen
A rare malignant tumor of the spleen that consists of blood vessels is:
Angiosarcoma
32 yr old female patient presents to the u/s dept for abd. sonogram. Evaluation of the spleen reveals a 1 cm rounded echogenic mass that does not produce acoustic shadowing. Diagnosis:
Hemangioma
In a patient with suspected lymphoma, the presence of Reed-Sternberg cells indicates:
Hodgkin lymphoma
histoplasmosis
Inhalation of an airbornne fungus that can affect the lungs and spread to other organs
The spleen is a
Intraperitoneal organ
Small echogenic foci scattered throughout the spleen is most likely
Multiple benign granulomas
All of the following are functions of the spleen except: A. storage of iron B. Defense against disease C. Blood resevoir D Destruction of phagocystic cells
Phagocytic cells
Angiosarcoma
Rare malignant tumor of the spleen that is derived from blood vessels
Type of tissue within the spleen that is responsible for its phagocystic function
Red pulp
Accessory spleen
Small round island of splenic tissue often located near the splenic hilum or near the tail of pancreas
48 yr old male patient with a Hx of severe, sudden onset LUQ pain w/o trauma presents to the u/s dept. for a sonogram of spleen. A wedged shaped hypoechoic area within the spleen is seen
Splenic infarct
splenic infarct
area within the spleen that has become necrotic because of lack of oxygen
35 yr old male patient presents to the u/s dept. for abd. scan with a hx of histoplasmosis. What are you more likely to identify within the spleen
Multiple granulomas
All of the following are associated with splenomegaly except: A. trauma B. hemolytic abnormalities C. Mono D. pancreatitis
Pancreatitis
complex cyst that results from the parasitic infestation of the spleen by a tapework
hydatid cyst
Bacterial endocarditis
infection of the surface of the heart that can spread to other organs
14 yr old male patient presents to the u/s dept after falling off bike. Sonogram reveals a complex appearing mass within spleen. Most likely is a
