Introduction
The incidence of renal cyst increases with age above 50 years. Majority of the cyst are < 2cm and the reports of size >15cm are extremely rare. Here we present a peculiar case of a 75-year-old male with an exceptionally massive renal cyst, but unremarkable symptoms.
Case Description
A 74-year-old Caucasian male with history of type 2 diabetes mellitus and hypertension who was admitted to the hospital for evaluation of chest pain of cardiac origin. Incidentally on exam, he was found to have a protuberant abdomen with fluid wave concerning for ascites. He has no known history of liver disease and he reported gradual increase in abdominal girth for last 15 years. He was further evaluated with CT abdomen and pelvis which demonstrated numerous fairly simple appearing cysts noted to arise from both kidneys. The largest arises from the lower pole of the left kidney and measures 40 x 27 x 30 cm. He denies any family history of polycystic kidney disease. Patient underwent continuous percutaneous catheter placement in largest cyst with 20L of serous fluid removed over 2 days with negative microbiology, and with significant improvement in abdominal distention thereafter.
Discussion
Renal cyst should be considered as one of the differentials in patients with progressive distension of abdomen. To the best of our knowledge, this case represents the largest reported renal cyst. Our findings highlight the fact that benign renal cyst can grow over several years while remaining relatively asymptomatic, can mimic ascites and can pose diagnostic and therapeutic dilemma.
