accessory spleen
___ a rare malignant tumor of the spleen that is derived from blood vessels
angiosarcoma
___: the congenital absence of the spleen
asplenia
___: the gradual fibrosis and dysfunction of the spleen
secondary to a disease
autosplenectomy
___ an infection of the surface of the heart that can spread to other organs
bacterial endocarditis
___: a growth disorder syndrome synonymous with enlargement of several organs including the skull, tongue, and liver
Beckwith–Weidemann syndrome
___: non-penetrating injury to the body
blunt trauma
___: the splenic process of removing irregular red blood cells from the bloodstream
culling
___: a herpesvirus that can lead to infectious mononucleosis
Epstein–Barr infection
___: the process of making red blood cells
erythropoiesis
___: the spleen’s hematopoietic function which
can return in cases of severe anemia
extramedullary hematopoiesis
___: small echogenic calcifications that result from inflammation of the tissue in that area
granulomas
___: an inherited disease that disrupts the normal immune system and causes it to malfunction resulting in immunodeficiency; chronic inflammation can lead to the development of granulomas in several organs
granulomatous disease

hydatid cyst
___: breaking down of a cellular membrane
lysis
___: an infectious disease caused by the Epstein–Barr virus
mononucleosis
___: carcinoma of the lymphocytes; cancer of the lymphatic system
non-Hodgkin lymphoma
___: the splenic process of cleaning red blood cells of unwanted material
pitting
___: having many small islands of splenic tissue
polysplenia
___: the elevation of blood pressure within the portal venous system
portal hypertension
___: specialized tissue within the spleen that performs its phagocytic function
red pulp
___: the cells that indicate the presence of Hodgkin lymphoma
Reed–Sternberg cells
___: a systemic disease that result in the development of granulomas throughout the body
sarcoidosis

splenic cleft
___: benign splenic mass that has been associated with Beckwith–Weidemann syndrome and tuberous sclerosis
splenic hamartoma
___: an area within the spleen that has become necrotic because of a lack of oxygen
splenic infarct
___: benign tumor composed of lymph spaces
splenic lymphangioma
___: the twisting of the splenic vasculature causing a disruption
in the blood supply to the spleen and subsequent ischemia
splenic torsion
___: enlargement of the spleen
splenomegaly
___: the implantation of ectopic splenic tissue possibly secondary to splenic rupture
splenosis
___: an accessory spleen
splenule
___: a systemic disorder that leads to the development of
tumors within various organs
