Discussion: The most common cause of splenic cysts are post-traumatic cysts, occuring 80% of the time. Other causes of splenic cysts include epidermoid cysts, pancreatic pseudocysts, bacterial abscesses, and hydatid cysts.Post-traumatic cysts are formed from previous hemorrhage and may contain blood products, cholesterol crystals, or cellular debris.ydatid cysts should be suspected in a patient with cysts in the liver, lung, and spleen. These cysts are typically large, and will have septations, daughter cysts, and hydatid sand. They may also have ringlike calcifications in chronic stages.
