The study was completed by a computed tomography (CT) of the abdomen and pelvis which revealed large septate intra-splenic cyst with fluid collection measuring 18 cm x 14 cm x 10 cm, located at the upper pole of the spleen away from the hilum (Figure 1).

Adhesions were cut, vessels were divided, and an upper pole partial splenectomy resecting the whole upper pole of the spleen including the entire cyst was done with hemostasis sutures sutured at the cut edge as shown in Figure 3.

Histopathological assessment of the removed part of the spleen with the cyst revealed primary non-parasitic splenic mesothelial in origin (arrows in Figure 4(A)), there was no squamous metaplasia, there was no evidence of clear septation or trabeculations (Figure 4(A)). Calratinin were positive supporting the primary mesothelial nature of the cyst (stained brown in Figure 4(B)). CEA staining was negative.
