Oversized pseudocysts of the spleen: Report of two cases: Optimal management of oversized pseudocysts of the spleen.

Introduction: Pseudocysts of the spleen are usually asymptomatic and associated with a history of trauma, infection or infarction. In this report, we present two uncommon cases of solitary, oversized pseudocysts of the spleen.

Presentation Of Case: Two patients (cases A and B), with symptoms of abdominal pain, were investigated. The laboratory and ultrasound examination confirmed the diagnosis of a large, non-parasitic splenic cyst in both cases. Computed tomography described an oversized pseudocyst occupying almost the entire splenic parenchyma in both cases and in patient A, the cyst was located in the splenic hilum. The medical history revealed a previous abdominal injury only in case A. The two patients underwent an open total splenectomy. The pathology examination verified the diagnosis of a non-parasitic splenic pseudocyst.

Discussion: Both patients presented with symptoms, in contrast to the majority of patients with splenic cysts. The medical history of patients with splenic pseudocysts does not always reveal the cause of the pseudocyst formation. Any type of spleen-sparing procedure is not easy to perform in cases of surgical and anatomical difficulty, because of recurrence and the risk of intractable bleeding from the spleen.

Conclusion: Partial splenectomy is the recommended method for parenchymal preservation, but total splenectomy is preferred when the splenic cyst is oversized or cannot be excised with safety.
