Splenic cysts that are non-parasitic are uncommon but pose a treatment dilemma, particularly when they occur in children. Generally, most experienced authors recommend operative intervention when the cysts is > 4-5 cm or symptomatic.
A variety of procedures have been tried with the optimal technique yet to be developed, although a spleen-sparing technique is desired. Partial splenectomy, percutaneous ultrasound-guided or laparoscopic cyst fenestration, unroofing with omental packing, and cyst wall removal with argon beam coagulation are described techniques.
Cyst recurrences generally mandate splenectomy.
