title: Asymmetric hyperthecosis ovarii.
abstract: Testosterone and delta4-androstenedione concentrations, in venous blood obtained by percutaneous retrograde femoral catheterization of the ovarian and adrenal veins bilaterally, demonstrated the left ovary to be the predominant secretory source of androgens in an 18-year-old virilized female. Histologic examination of the excised ovarian tissue revealed asymmetric hyperthecosis ovarii and confirmed the biochemical data. This study demonstrates the accuracy of the venous catheterization method in locating preoperatively the hypersecretory source of androgens in virilized women. The favorable postoperative clinical result emphasizes the importance of an accurate preoperative diagnosis in virilized women even in the absence of ovarian neoplasia.
