An epididymal cyst is a fluid-filled sac in a long tube near the testicle. It is not a type of cancer.
Epididymal cyst is more common in men over 40 years of age. Men whose mothers were given diethylstilbestrol (DES) during pregnancy may be at higher risk. This drug has not been used since 1971.
Most men do not have symptoms. They may notice a lump or mass in the testicle or on the side of the scrotum. Some men may have pain.
You will be asked about your symptoms and health history. A physical exam will be done. An image may be taken to confirm the diagnosis. This can be done with an ultrasound.
The cyst may go away in time. Men with a large, painful cyst may need surgery to remove it. A small incision will be made in the scrotum. The cyst will be taken out. Stitches will be used to close the incision.
