Introduction Non-parasitic spleen cyst (NSC) is a relatively rare and difficult to diagnose disease, which rapture due to a traumatic impact to the spleen, can lead to the peritonitis. Case presentation We present the case of a 30-year-old woman with a 7.5 × 7.5 × 5 cm NSC, who underwent the microwave ablation (MWA) of the splenic cyst. Results The procedure was performed under intravenous anesthesia. MWA of the cysts was performed using a probe placed in the cavity of the cyst, with the frequency of 902–928 MHz delivered during 15 minutes. The postoperative period was uneventful, and the patient was discharged after 2 days. Conclusion We demonstrated that MWA can be utilized as a novel, minimally-invasive, and cost-effective approach in NSC treatment.
