Introduction: Splenic pseudocysts are extremely rare and seen in <1% of splenectomies. Approximately 800 cases have been reported in the literature. It is important to distinguish splenic pseudocysts from more common lesions such as hydatid cyst and spleen abscess. In this study, we aimed to evaluate splenic pseudocysts which are rare and difficult to diagnose.

Material & Methods: Patients with splenic pseudocysts identified in histopathological examination between January 2010 and January 2016 were retrospectively reviewed. All patients evaluated for demographic datas, outcomes of imaging studies and the development of postoperative complications.

Results: In the histopathological examination, splenic pseudocysts were detected in 5 patients. The average size of the cysts was 8 cm. Two of the patients were asymptomatic with incidentally detected cysts, while left upper quadrant pain was found in 3 patients. None of the patients had a history of trauma. In the ultrasonographic examination, well-circumscribed and homogeneous content cysts were found in the spleen in all patients. In the computed tomography, thick-wall, capsulated and well- circumscribed cysts were identified. Laparoscopic splenectomy was performed in 4 patients, while 1 patient underwent splenectomy with left subcostal incision. The mean follow-up duration was 26 months. No additional complications occurred during follow-up.

Conclusion: Splenectomy is the gold standard treatment modality in splenic pseudocysts. However, partial splenectomy, percutaneous aspiration and cystectomy have also been described in the treatment of pseudocysts.
