Ejaculatory duct cysts are a rare type of cyst of the prostate gland.
They occur due to obstruction of the ejaculatory duct which in turn can either be congenital or secondary (e.g. inflammation).
They are usually intraprostatic when small but may extend cephalad when large.
Typically seen as round or oval lesions. They tend to be in a medial or paramedial position in the prostatic gland above the level of the verumontanum, extending into the prostatic base.
Signal characteristics include 2:
- T1: low or high signal intensity
- T2: high signal intensity
