- these are important surgically since splenomegaly can be diagnoses clinically by palpation or X-ray and some tumours are surgically curable
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
Haemangiosarcoma
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
