Definition / general
  • Splenic metastasis is usually associated with extensive metastases - isolated splenic metastasis is rare
  • Metastasis may be rare due to spleen's immunological function
  • Metastases developed by hematogenous, lymphatic or abdominal cavity implantation routes; also direct invasion from lesions in adjacent organs
  • Hematogenous or direct seeding is more common

  • By radiological examination followed by histopathological confirmation
