Congenital abnormalities of the female genital tract are relatively common. Torsion of an ovarian cyst complicating pregnancy is frequently encountered. However, a twisted undescended ovarian cyst whose stalk passes through an open intersigmoid fossa has not been previously reported, as far as we could discover.
A review of the literature revealed many cases of ectopia of the ovary, but almost invariably the ectopic ovaries were situated in the inguinal region. Packard and Rector1 in 1948 collected more than 300 cases of inguinal ectopia of the ovary. Occasionally2 an ovarian cyst is found in an inguinal hernial sac. Van Meurs3 reported strangulation of an ovary and a fallopian tube in an obturator hernia. Although many anatomic variations were noted, there was no reference to an ovary herniating through the intersigmoid fossa.
