肾脏上极更大的单纯性肾囊肿，还有一些小囊肿散布于肾脏。左侧输尿管通向南面。放射影像学检查可以发现这样大小的囊肿。根据其囊内液体的密度可以把它和肿瘤区别开来。
Here is a much larger simple renal cyst of the upper pole. Other smaller cysts are also scattered around the kidney. The ureter exits south on the left. Such a large renal cyst would be seen on a radiographic imaging procedure, but could probably be distinguished from a neoplasm by its fluid density.
