Emphysematous Cyst Infection Mimicking Gastric Bubble After Renal Cyst Sclerosing Therapy.

Abstract

A 59-year-old man with type 2 diabetes mellitus and hypertension presented to the emergency department with a 4-day history of coughing and an intermittent fever. He had received ultrasonography-guided percutaneous puncture via left flank with ethanol injection for renal cyst sclerosing therapy approximately 2 weeks earlier. On physical examination, he was well oriented and febrile (39.8°C) with high blood pressure (194/88 mm Hg) and tachycardia (heart rate 131 beats/min). His abdomen and back were soft without tenderness or erythematous change.
