The most common cause of a lymphocele is due to a surgical procedure. If the lymphatic vessels are damaged during a surgical procedure, lymphatic fluid can leak into the surrounding tissue, resulting in an abnormal accumulation of fluid.
Lymphoceles can also be caused by:
- Trauma: Injury to the lymphatic system can cause lymphoceles to form.
- Radiotherapy: Radiotherapy can damage lymphatic vessels and lead to the formation of lymphoceles.
- Cancer: Cancer can block or damage lymphatic vessels, which can lead to the formation of lymphoceles.
- Infection: An infection can cause inflammation of the lymph vessels, which can lead to the formation of a lymphocele.
