Cysts of the spleen are rare disease that affects the spleen. They are divided into primary and secondary in relation to the etiology and histopathology. We report two young patients of a boy aged 16 and a girl of 15 godina. Ultrasonography and CT of the abdomen showed a large cystic mass in the spleen unclear origin. On laparotomy for both the patient was found a large cyst that reached to the upper pole of the spleen and required total splenectomy. Histopathology showed fibrous cyst wall with areas of hyaline degeneration below which there is significant blood kongstion.Etipatogenesis and different modalities of treatment for cysts of the spleen are questionable. Although pseudocysts of the spleen are rare, they must be considered in the differential diagnosis of abdominal masses in the upper abdomen in young adolescents.
