ABSTRACT: HintergrundAls Ursache einer sich rasch entwickelnden schweren Virilisierung mit exzessiver Hyperandrogenmie knnen hormonproduzierende Tumoren, z.B. der Nebennierenrinde sowie der Ovarien, in Frage kommen. Wichtigste therapeutische Manahme bleibt die Tumorexstirpation, welche bei Malignittsausschluss organerhaltend erfolgen kann. Zur Lokalisationsbestimmung kommen blicherweise Verfahren wie Vaginalsonographie, Computertomographie sowie Magnetresonanztomographie in Betracht; ausgewhlten Fllen bleiben Untersuchungsmethoden wie Szintigraphie sowie selektive Venenkatherisierung vorbehalten.KasuistikWir berichten ber eine Patientin mit ausgeprgter Hyperandrogenmie wegen einer ovariellen Leydig-Zell-Neoplasie, bei der die exakte Tumorlokalisation erst intraoperativ durch selektive Katheterisierung der Ovarvenen nachgewiesen wurde. Neben der Darstellung der hormonbedingten phnotypischen Vernderungen sowie der Hormonbefunde werden insbesondere bildgebende Manahmen zur Tumorlokalisation diskutiert.SchlussfolgerungBei klinisch hochgradigem Verdacht eines androgenproduzierenden Ovartumors fhrt in seltenen Fllen erst eine explorative Laparotomie mit selektiver Katheterisierung der Ovarvenen zur Ermittlung der Tumorlokalisation.BackgroundExcessive androgen production with severe virilization might be caused by androgen-secreting tumours, e.g. of adrenal or ovarian origin. The treatment of choice remains the surgical removal of the tumour, which might be performed by organ-preserving surgery in cases of benign histology. Imaging procedures such as pelvic ultrasound, computed tomography and magnetic resonance imaging or—in selected cases—cholesterol scintigraphy and selective vein catheterization are to help to localize the tumour.CaseWe report on a patient with severe hyperandrogenaemia due to an ovarian Leydig cell neoplasia, with the tumour exactly localized by selective blood sampling of the ovarian veins during an exploratory laparotomy. The hormonally induced changes of the patients phenotype in combination with serological results are presented, and imaging procedures for localization of the tumour are discussed.ConclusionIn selected cases androgen-producing tumours of the ovaries might only be localized during exploratory laparotomy with intraoperative selective blood sampling of the ovarian veins.Gynäkologische Endokrinologie 01/2006; 4(2):120-122. -

ABSTRACT: Androgen excess in women is manifested typically by clinical features that may include hirsutism, acne, central obesity, male-pattern baldness, upper torso widening, increased waist-to-hip ratio, clitoral hypertrophy, and deepening of the voice. The differential diagnosis includes androgen-producing ovarian and adrenal neoplasms, Cushing's syndrome, polycystic ovary syndrome, and the intake of exogenous androgens. Physicians treating patients for one symptom of androgen excess must be alert for other symptoms and signs. The cosmetic manifestations of androgen excess belie the serious health risks associated with this condition, including cardiovascular disease, intravascular thrombosis, and insulin resistance. Prompt clinical recognition of androgen excess, understanding of the androgen-related biochemical abnormalities underlying the risks associated with this condition, and implementation of risk modification can reduce the incidence of associated morbidity and mortality. An interdisciplinary approach to management is strongly recommended. Risk reduction strategies include correction of dyslipidemias, low-dose aspirin for primary prevention of myocardial infarction, maintenance of ideal weight, smoking cessation, exercise, use of oral contraceptives containing a low-androgenic progestin, and postmenopausal estrogen replacement. Combination oral contraceptives containing low-androgenic progestins are effective not only in reducing signs of androgen excess but also in potentially retarding the progression of long-term sequelae such as cardiovascular disease.The American Journal of Medicine 02/1995; 98(1A):137S-143S. · 5.43 Impact Factor
