Differential Diagnosis for Elevated Testosterone and DHEA in a 21-Year-Old Female

Single Most Likely Diagnosis

  • Polycystic Ovary Syndrome (PCOS): This condition is characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. Elevated testosterone and DHEA levels are common in PCOS, making it a likely diagnosis given the patient's age and symptoms.

Other Likely Diagnoses

  • Congenital Adrenal Hyperplasia (CAH): Although less common, CAH can present with elevated androgen levels, including DHEA. The non-classic form of CAH may not be immediately apparent and could be considered with these lab results.
  • Androgen-Secreting Tumors: Rarely, tumors of the ovaries or adrenal glands can produce excess androgens, leading to elevated testosterone and DHEA levels.
  • Idiopathic Hyperandrogenism: This diagnosis is considered when hyperandrogenism is present without a clear underlying cause, such as PCOS or CAH.

Do Not Miss Diagnoses

  • Cushing's Syndrome: Although less likely, Cushing's syndrome can cause elevated androgen levels due to adrenal gland overproduction of cortisol and androgens. Missing this diagnosis could lead to significant morbidity due to uncontrolled cortisol levels.
  • Adrenal Carcinoma: A rare but potentially deadly diagnosis, adrenal carcinoma can produce excess androgens. Early detection is crucial for treatment and survival.

Rare Diagnoses

  • 17,20-Desmolase Deficiency: A rare genetic disorder affecting steroid synthesis, leading to an imbalance in sex hormone production.
  • Gonadal Dysgenesis: Conditions like Swyer syndrome can lead to abnormal gonadal development and potentially affect hormone levels, though this would typically be identified earlier in life.
  • Exogenous Steroid Use: The use of anabolic steroids or other exogenous hormones could artificially elevate testosterone and DHEA levels, though this would typically be associated with a clear history of substance use.
