Formation of Pedicle of an Ovarian Cyst. Most ovarian cysts are pedunculated, the pedicle being made upof structures which connect the cyst Avith the uterus, broad ligament,round ligament, Fallopian tube, ovarian artery, and ovarian vein. PAROVARIAN CYSTS. The parovarium from which parovarian cysts spring is the remnantof the Wolffian body (primitive kidney) and has no known physiologicalsignificance. The epididymis and vasa efferentia in the male also spring FiGUKE. SmaU parovarian cyst. This cyst has sprung from the parovarium, and is therefore entirelydistinct from the ovary : to the right is the hydatid of Morgagni suspended from a long, slenderpedicle, which is attached to one of the fimbriated extremities of the Fallopian tube. Thehydatid of Morgangi has been known to grow to the size of a small orange, and it then has thesame general appearance as the parovarian cvst, but is distinguished from it by the fact that itsprings from the extremity of the Fallopian tiibe. The Fallopian tube shows numerous pointsof expansion and constriction, one of them being at the isthmus; this is known as salpin-gitis isthmica nodosa, common in gonorrhceal salpingitis. Myoma and adenomyoma of thetube present a gross appearance similar to that of salpingitis isthmica nodosa. This conditionof the tube is rarely found in connection with cysts of the parovarium. from the Wolffian body and
