Ovary

Peri-testicular bursa - (peri-testicular bursa, lat. Paroophoro-ovarium) is an unpaired organ associated with the ovary and containing the ovarian and fallopian tubes along with an ectopic cyst and other elements of the female reproductive system. Other tumors can occur in the peritesticular bursa, including teratoma (germ cell tumor), which can result in the sudden appearance of a palpable testicle in the bursa.
