Virilising ovarian tumour in a woman with an adrenal nodule

The Masquerading, Masculinizing Tumor: A Case Report and Review of the Literature

Androgen-producing tumors in women are rare neoplasms that can cause secondary virilizing characteristics. Of patients presenting with symptoms of hyperandrogenism, these tumors are found in ∼0.2% of cases. Androgen-producing tumors can arise from the ovary or the adrenal gland. Those arising from the ovary are rare, accounting for <5% of all ovarian tumors. This case presents a hilar Leydig cell tumor of the ovary, which resulted in secondary virilization of a 45-year-old female 2 months after cessation of combined oral contraceptives (COC). Laboratory findings showed markedly elevated total and free testosterone concentrations with normal dehydroepiandrosterone sulfate, however neither pelvic ultrasound nor magnetic resonance imaging demonstrated any masses. Venous sampling under fluoroscopy revealed supraphysiologic testosterone concentrations from the right ovarian vein suggesting the source. The patient underwent bilateral salpingo-oophorectomy revealing a 1.3 cm hilar cell tumor of the right ovary. This article reviews the clinical features, diagnosis, and treatment of hilar Leydig cell tumors and describes the long-term complications of supraphysiologic testosterone levels. As the tumor presented after cessation of COC, we also review the mechanisms by which COC might suppress supraphysiologic androgen levels and mask the secondary virilizing effects of androgen-producing tumors.

Imaging of Adrenal-Related Endocrine Disorders

Endocrine disorders associated with adrenal pathologies can be caused by insufficient adrenal gland function or excess hormone secretion. Excess hormone secretion may result from adrenal hyperplasia or hormone-secreting (ie, functioning) adrenal masses. Based on the hormone type, functioning adrenal masses can be classified as cortisol-producing tumors, aldosterone producing tumors, and androgen-producing tumors, which originate in the adrenal cortex, as well as catecholamine-producing pheochromocytomas, which originate in the medulla. Nonfunctioning lesions can cause adrenal gland enlargement without causing hormonal imbalance. Evaluation of adrenal-related endocrine disorders requires clinical and biochemical workup associated with imaging evaluation to reach a diagnosis and guide management.

Diagnostic Dilemma in Two Cases of Hyperandrogenism

Hirsutism is a common endocrine complaint affecting about 10 percent of women. It may be caused by multiple etiologies including adrenal and ovarian disorders. Usually, it is a result of a benign entity such as PCOs and idiopathic hirsutism. However, sometimes especially when it is severe and rapid in progression an androgen-secreting tumor should be excluded. Sertoli-Leydig cell tumors constitute fewer than 0.5 percent of ovarian tumors and it may be benign or malignant. In this article, we present two cases of hyperandrogenism caused by occult ovarian Leydig cell tumors. one of them was confounded by the presence of coincidental bilateral adrenal nodules that complicated the diagnostic process. Tumor dissection was curative in both cases and the diagnosis was confirmed by pathological and hormonal testing after surgery.
