Differential Diagnosis for 31F with Elevated DHEA, Elevated Testosterone, and Infertility
Single Most Likely Diagnosis
- Polycystic Ovary Syndrome (PCOS): This is the most likely diagnosis given the patient's symptoms of elevated androgens (DHEA and testosterone) and infertility. PCOS is a common endocrine disorder in women of reproductive age, characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovaries.
Other Likely Diagnoses
- Congenital Adrenal Hyperplasia (CAH): Although less common than PCOS, CAH can cause elevated DHEA and testosterone levels due to adrenal gland dysfunction. It's essential to consider this diagnosis, especially if the patient has a family history or other symptoms like virilization.
- Androgen-Secreting Tumors: Ovarian or adrenal tumors can produce excess androgens, leading to elevated DHEA and testosterone levels. These tumors are relatively rare but can cause significant symptoms and infertility.
- Cushing's Syndrome: This rare endocrine disorder is caused by excess cortisol production, which can also lead to elevated androgen levels. However, Cushing's syndrome typically presents with other symptoms like weight gain, hypertension, and glucose intolerance.
Do Not Miss Diagnoses
- Adrenal Carcinoma: Although rare, adrenal carcinoma can produce excess androgens and has a poor prognosis if left untreated. It's crucial to consider this diagnosis to avoid delayed treatment.
- Pituitary Tumors: Pituitary tumors, such as prolactinomas or non-functioning adenomas, can disrupt normal pituitary function, leading to elevated androgen levels and infertility.
Rare Diagnoses
- 17,20-Desmolase Deficiency: This rare genetic disorder affects the production of androgens and can cause elevated DHEA and testosterone levels.
- Gonadal Dysgenesis: This condition is characterized by abnormal gonadal development, which can lead to elevated androgen levels and infertility.
- Hyperthecosis: A rare condition where the ovarian stroma produces excess androgens, leading to elevated DHEA and testosterone levels.
