An abnormal enlargement of the spleen that can develop from infections is called <u>splenomegaly</u>.
Infections, such as mononucleosis, are among the most common causes of splenomegaly. Liver problems such as cirrhosis and cystic fibrosis, can also cause an enlarged spleen.
Another possible cause of splenomegaly is juvenile rheumatoid arthritis. This condition can cause inflammation of the lymph system.
An enlarged spleen causes serious complications or the cause can't be identified or treated, surgery to remove your spleen (splenectomy) might be an option. In chronic or critical cases, surgery might offer the best hope for recovery. Elective spleen removal requires careful consideration.
