Q

What is the most common sonographically visualized abnormality of the spleen

25
What is the most common cause of splenomegaly
portal hypertension
26
___________ ___________ ______________ may cause a small shrunken spleen
Sickle cell anemia
27
Sonographically what is the splenic echogenicity when splenomegaly occurs?
Could be hyperechoic or hypoechoic but does not correlate with the cause of the enlargement

A patient with sickle cell disease presents for an abdominal sonogram complaining of recent left upper quadrant pain. A hypoechoic wedge shaped lesion is seen in the spleen. What is this typical of?
Splenic infarct

The spleen is located in the __________ cavity and is covered y peritoneum except at the ______________
peritoneal splenic hilum

In the spleen, which structure is made up of lymph tissues arranged around splenic arteriole?
White pulp
38
What is the spleens function in the embryological stage of development?

What function requires B cells and T cells?
Immunology
49
What splenic function removes senescent, defective red blood cells?
Culling

What is considered a relatively common anatomic variant of the spleen
Acccessory spleen
52
The spleen is more susceptible to what pathology when there are no adequate anastomoses between the arteries in the spleen
Infarction
