A Huge Primary Congenital Splenic Cyst Diagnosed in a Middle-Aged Female Patient: A Case Report

Splenic cysts are classified into primary (true) and secondary (pseudo or false) cysts. Primary non-parasitic congenital splenic cysts are comparatively rare, particularly in the middle-aged population. We present a rare case of a huge primary congenital splenic cyst, incidentally discovered in a female patient in her mid-50s. This case report aims to highlight the uncommon presentation of primary congenital splenic cysts in middle age and emphasizes the necessity of considering primary congenital splenic cysts in the differential diagnosis even in patients beyond middle age.
