Benign splenic cyst

Abstract

Objective: To report a case of a large benign splenic cyst in a young patient during the postpartum period, emphasizing the clinical, diagnostic, and therapeutic aspects, as well as the importance of imaging investigation and timely surgical management to prevent complications. Case details: A 30- year-old previously healthy woman presented with progressive abdominal enlargement that began after vaginal delivery, associated with early postprandial fullness and no other systemic symptoms. Physical examination revealed marked splenomegaly. Computed tomography showed a large intrasplenic cystic lesion measuring approximately 21.7 × 16.7 × 21.7 cm, with inferior displacement of the spleen and compressive effect on adjacent structures. Ultrasonography suggested an encapsulated hematoma secondary to splenic capsular rupture. Based on clinical presentation and imaging findings, surgical treatment was indicated, and total splenectomy was performed via laparotomy. The patient had an uneventful postoperative course and was discharged with appropriate vaccination guidance. Histopathological examination confirmed a simple subcapsular splenic cyst with no evidence of malignancy. Final considerations: Giant splenic cysts, although rare, may cause compressive symptoms and require surgical intervention. Early diagnosis and appropriate management are essential to prevent severe complications, particularly in young patients.
