If there is a meatball attached to the testicle, then it may be normal epididymal tissue, or it may be a nodule or epididymal nodule of the testicle. It is recommended to go to the hospital for relevant examination to clarify the specific causes: 1. There is normal epididymal tissue attached to the posterior and lateral side of the testicle in the shape of a stripe, with a slightly expanded head and tail, and a slightly slender epididymal body. Therefore, in the posterior chamber of the testis, you can touch the stripe-like sarcoma tissue with relatively large head, soft texture, no local pain and no swelling, which is normal epididymal tissue and can be identified by ultrasound examination. 2. Nodules of the epididymis or testes, which occur after orchitis or epididymitis, are hard textured nodules when touched, such as scarring after inflammation, usually without obvious pain, but There may be swelling and pain during the acute phase of infection; 3. If confined to the head of the epididymis, it may also be due to semen retention cysts, seen in the formation of chronic retention of semen due to obstruction of the seminal tract, which can be identified by ultrasound examination of the testes and epididymis.
