Introduction
Splenic Neoplasms and benign hyperplasia are consideration once splenomegaly has been detected clinically by palpation or following radiography - some splenic neoplasias are surgically curable.
Hyperplastic Nodules or Benign Lymphoma
These are a very common incidental findings in older dogs that can occasionally be mistakenly for malignant masses. They 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
Rarely these nodules may rupture and give rise to haemorrhage.
Haemangioma
Haemangiosarcoma
Haematopoietic Neoplasms
Lymphosarcoma
myeloid (granulocytic) leukaemia
- rare
- all species
- extreme form with spleen approaching liver size
systemic mastocytosis
- cat
- extreme form with spleen approaching liver size
