Abstract:
Benign renal cysts are fluid-filled sacs that originate from the kidneys. Infected renal cysts are a rare manifestation of benign renal cysts, that can be managed with antibiotic therapy, drainage, and surgery. A 74-year-old man was admitted to our hospital with an infected renal cyst. Initial treatment managed with only broad-spectrum antibiotics, as percutaneous drainage was postponed due to apparent clinical improvement. However, his condition deteriorated, leading to cardiac arrest. Radiological intervention with cyst drainage resulted in rapid improvement. The patient recovered successfully and was discharged 16 days later. A follow-up computed tomography revealed a marked reduction in cyst size, with normal blood and urine tests, and the patient remained asymptomatic.
