Massive splenomegaly…Answer


Last week I showed you this CT showing massive splenomegaly:

Splenomegally + Masses

 

The abdominal CT above shows massive splenomegaly with various areas of hypo attenuation throughout the spleen.  Massive splenomegaly is a term used when the volume of the spleen is expected or calculated to be >1000 grams or clinically extends well into the left lower quadrant or past midline.

A short differential diagnosis for massive splenomegaly includes (1):

  • Malaria
  • Myelofibrosis
  • Leukemia (especially CML)
  • Polycythemia Vera
  • Lymphoma (several types)
  • Lieshmaniasis
  • Thalessemia

The ill-defined hypo attenuated lesions in this spleen raise a high concern for lymphoma.
