There are small cysts in the epididymis?


Hello, doctor! A few days ago, I had an ultrasound due to varicocele and found a small cyst about 0.6 cm on the epididymis.
Doctor, is it possible for this cyst to resolve on its own?

Dr. Sun Hongshun reply Urology


Hello: Many organs and tissues in the body can develop cysts, such as the liver, kidneys, and as you mentioned, the testes.
Generally speaking, their etiology is unclear, and they are unlikely to resolve on their own.
It is advisable to have regular follow-up appointments to monitor for any changes in size or quantity.

More Info


Epididymal cysts, also known as spermatic cysts, are fluid-filled sacs that develop in the epididymis, which is the coiled tube located at the back of the testicle that stores and matures sperm. These cysts are generally benign and often do not cause any symptoms. In many cases, they are discovered incidentally during imaging studies, such as ultrasounds, performed for other reasons, like your recent examination for varicocele.

To address your question, yes, epididymal cysts can sometimes resolve on their own. Many small cysts, particularly those that are asymptomatic and less than 1 cm in size, may not require any treatment and can spontaneously decrease in size or disappear over time. However, this is not guaranteed, and the behavior of these cysts can vary from person to person.
The management of epididymal cysts typically depends on their size, symptoms, and any associated conditions. If the cyst is small, asymptomatic, and not causing any discomfort, a "watchful waiting" approach is often recommended. Regular follow-up with your healthcare provider may be suggested to monitor the cyst for any changes. If the cyst grows larger, becomes painful, or causes other symptoms, treatment options may include aspiration (removal of fluid) or surgical excision.

In terms of self-care and lifestyle modifications, there are no specific measures proven to expedite the resolution of epididymal cysts. However, maintaining a healthy lifestyle, including regular exercise and avoiding activities that may cause trauma to the groin area, can be beneficial. You mentioned that you exercise regularly, which is great for overall health. If you experience discomfort while cycling, consider using a more comfortable bike seat designed to reduce pressure on the perineal area, as this may help alleviate any potential discomfort.

Regarding your concerns about the cyst and its implications, it’s essential to have open communication with your urologist. They can provide personalized advice based on your specific situation and the characteristics of the cyst. If you notice any changes, such as increased size, pain, or other symptoms, it is crucial to seek medical attention promptly.

In conclusion, while epididymal cysts can sometimes resolve on their own, monitoring and follow-up with your healthcare provider are essential. If you have further questions or concerns, do not hesitate to reach out to your urologist for more tailored guidance. They can help you understand the nature of the cyst and any necessary steps moving forward.
