Pathology

They can occur in both traumatic and non-traumatic situations.

Radiographic features

CT

Imaging in the portal venous phase is best for detection. CT typically shows a crescentic/lenticular perisplenic collection where attenuation values depend on the age of the haematoma. The haematoma may flatten or indent
the lateral margin of the spleen 6.

  • acute: hyperattenuating to isoattenuating 4,  then called subcapsular haemorrhage
  • subacute: iso attenuating, within 1-2 days of bleeding, CT attenuation values of splenic haematomas may be equal to or greater than that of the splenic
    parenchyma 6
  • established/chronic: hypoattenuating
