An Epidydyma Cysts is a fluid-fill sac that develops in the epididymis which is a small tube located near to the upper testicle.
Often, these are caused when sperm collects in the epididymis and they develop for no apparent reason. They are more common than people might realise which means that around 30% of men will suffer with them. Commonly, men between the ages of 20 and 50 are more likely to develop them.
In the majority of cases, they are painless and so, there might not be any apparent symptoms. However, most will come across the lump when examining the testicles. If they cyst increases in size then it is common to feel a heaviness in the testicle and you might also notice a mass or swelling.
Your doctor will carry out a few tests to ensure that it is a cyst and not a tumour. This will begin with a physical example and then it is likely that you will have a transillumination or an ultrasound. The transillumination test will help to determine whether this is a cyst or a mass. If no fluid is detected then you will be sent for an ultrasound.
In many cases, there is no need for treatment while any pain or discomfort can be managed with painkillers. If an infection is present then patients are prescribed antibiotics. If the pain and pressure cause further discomfort then the procedure of aspiration could be carried out whereby a needle is inserted to remove some of the fluid.
Should the cysts refill, then a procedure known as sclerotherapy could be carried out. The fluid is drained from the cyst and then a substance is used to that causes the sac to fill with scar tissue. This can reduce the chance of the cyst returning but there is a risk to the epididymis.
In rare cases and if the cyst is affecting everyday life then surgery may be necessary. Here, the surgeon will make an incision and remove the growth.
