Why is swelling in the testes diagnosed as a hydrocele rather than a spermatocele or variocele in testicular torsions?

Answer 1

spermatocele (sperm-ă-toh-seel) n. a cystic swelling in the scrotum containing sperm. The cyst arises from the epididymis and can be felt as a lump above the testis. Treatment is by surgical removal.

hydrocele (hy-droh-seel) n. the accumulation of watery liquid in a sac, usually the sac surrounding the testes. This condition is characterized by painless enlargement of the scrotum.

varicocele (va-ri-koh-seel) n. a collection of dilated veins in the spermatic cord. It usually produces no symptoms apart from occasional aching discomfort. In some cases varicocele is associated with oligospermia, which can be improved by surgical correction or radiological embolization of the varicocele (varicocelectomy).


Well here you see the differences. They are all different and hydrocele is the most common, not painful and least serious.
