NB:Be aware of age-related changes regarding the spleen

Splenic Lesions

splenomegaly is the main clinical finding associated with the spleen in disease

Splenitis

Anthrax

Splenic Torsion

Haemolytic Anaemia

Chronic Venous Congestion

this may be seen along with chronic venous congestion of the liver in cases of chronic cardiac failure

Barbituates

administration of barbituates can produce a degree of splenomegaly due to splenic engorgement by erythrocytes

Splenic Neoplasia

Infarction

Rupture

+Barbituates
 * administration of barbituates can produce a degree of splenomegaly due to splenic engorgement by erythrocytes
-===Splenic Tumours===
-*these are important surgically since splenomegaly can be diagnoses clinically by palpation or X-ray and some are surgically curable
+[[Splenic Neoplasia]]
-====Hyperplastic Nodules or Benign Lymphoma====
-*very common incidental findings in older dogs
-*should not be mistakenly identified as pathognomic lesions
-*consist of nodules of hyperplastic white and red pulp
-:- usually 1-2 cms in size, but occasionally may be larger
-:- spherical
-:- protrude hemispherically from the surface as yellow and red mottled nodules
-*infrequently, may rupture and give rise to haemorrhage
-====Haemangioma====
-*benign tumour of dogs
-*may grow to considerable size
-:- the size of the lesion giving rise to clinical signs is compounded by haemorrhage from and into the tumour
-:- thus, a large mass of apple size may be found protruding from the spleen and adherent to the omentum
-*on section, it is largely blood clot
-*responds well to surgery
-:- therefore it must be distinguished from haemangiosarcoma
-====Haemangiosarcoma====
-*highly malignant tumour of dogs
-*distinguished from the superficially similar haemangioma by the presence of much more formed, solid tumour tissue
-*accurate prognosis demands histological examination
-*secondaries are common locally in the [[Peritoneal cavity - Anatomy & Physiology#Omentum|omentum]] and in the [[Liver - Anatomy & Physiology|liver]]
-:- course is usually short, often only a month or two
-:- metastases may occur in almost every organ
-====Haematopoietic Neoplasms====
-=====lymphosarcoma=====
-* splenomegaly occurs in multicentric lymphosarcoma
-*splenic enlargement may be marked if any form of lymphosarcoma is in leukaemic phase
-=====myeloid (granulocytic) leukaemia=====
-*rare
-*all species
-*extreme form with spleen approaching liver size
-=====systemic mastocytosis=====
-*cat
-*extreme form with spleen approaching liver size
