The majority are benign, simple cysts that can be monitored and not intervened upon. However, some are cancerous or are suspicious for cancer and are commonly removed in a surgical procedure called nephrectomy. Numerous renal cysts are seen in the cystic kidney diseases, which include polycystic kidney disease and medullary sponge kidney. A Bosniak I cyst is a simple cyst which has a hairline-thin wall, without calcifications, septations, or enhancement. A Bosniak II cyst is minimally complicated. It may show a few hairline-thin septa, with small or short segment calcification in the cyst wall/septa.
