splenic nodules with bloody consistency
Pseudo-infarcts
Agonal change- immediately before death- terminal circulatory failure
multifocal incompletely contracted areas of the spleen- paler areas with wrinkled capsule
Primary or metastatic splenic vascular neoplasms
haemangioma- benign neoplasm of vascular endothelium- rare, usually solitary masses covered by thin shiny serosa
haemangiosarcoma- most common primary and secondary MALIGNANT neoplasm of spleen - single to mulitple discrete to coaslescing dark red masses, often rupture- haemoperitoneum and hypovolaemic shock
Haematomas
Benign nodular hyperplasia
abnormal blood flow through the nodule
splenic vascular neoplasms
Trauma induced
Rupture of blood vessels
Acute infarcts due to venous thrombosis
any time you put extra cells in spleen you run the risk of infarction
edges of spleen
End-artery system
Acute are slightly more wet with chronic being paler, sunken, firmer- necrotic
discrete raised dark red- haemorrhagic infarcts
discrete raised and pale if arterial occlusion
Causes: vascular endothelial damage, hypercoagulable states septic emboli
