Because the spleen can be affected differently by different diseases, it is difficult to say how many children have spleen problems.

Children with enlarged spleens may be at risk for rupturing (breaking open) the spleen, which is a life-threatening emergency.

Sometimes, the cause of an enlarged spleen is temporary, such as infectious mononucleosis, and sometimes it is chronic, such as a blood disease.
