Spleen Quiz Answers


1.  Which structure does not border the spleen

A. the stomach
B. the colon
C. the diaphragm

C: The diaphragm does not immediately border the spleen. Stomach (medial), left kidney (inferior), colon (anterior), pancreas (medial, in contact with the splenic hilum).


2.  Failure of the splenic buds to unite leads to:

A. asplenia
B. accessory spleens
C. splenic cysts


B: Embryological development of a functional spleen is dependent on coalescence of splenic buds. Failure of this fusion leads to ectopic accessory spleens.


3.  What condition could a patient have who presents with an MRI of the spleen seen on the right:

A. splenic trauma
B. abscess
C. hepatitis C
D: epidermoid cysts


C: The MRI image demonstrates hypointense lesions in the spleen that do not enhance even after administration of gadolinium. These Gamna-Gandy bodies represent sites of hemosiderin deposition in the spleen consistent with hemosiderosis or hemochromatosis. Hemosiderosis is the result of increased tissue deposition of iron without organ damage, Hemochromatosis maybe of primary origin (causes: idiopathic, genetic) or secondary (chronic anemia necessitating multiple blood transfusions, cirrhosis--Hepatitis, EtOH).


4.  What is the diagnosis for the condition seen on the ultrasound on the right:

A. epidermoid cyst
B. abscess


B: Splenic abscesses usually present in a rounded or lobulated form on CT. Detecting these abscesses should involve an echocardiogram, as a major primary source of these abscesses is bacterial endocarditis.


5.  Which of the following is not part of the differential for the ultrasound seen on the right:

A. metastatic disease
B. abscesses
C. post-traumatic cysts
D: all of the above


D: The ultrasound image shown is consistent with all of the listed pathology.
