title: Case report: A rapidly expanding testicular mass due to a ruptured ovarian follicle.
abstract: An ovotestis is the commonest gonad in the small number of patients who are true hermaphrodites. In the majority of ovotestes, testicular and ovarian tissue is arranged end-to-end. There has been only one previous report of the sonographic appearances of an ovotestis. We present the sonographic findings in a patient who developed a rapidly enlarging upper pole testicular mass, which was found on histology to be a ruptured ovarian follicle with spermatogenesis occurring within the adjacent testicular tissue.
