Elevated DHEA: Clinical Manifestations and Diagnostic Approach

Clinical Presentation

The American College of Obstetricians and Gynecologists notes that hirsutism, acne, androgenic alopecia, menstrual irregularities, and infertility in females are common manifestations of elevated DHEA, with severity and presentation depending on the underlying cause 1, 2
Hyperandrogenism is indicated by excessive terminal hair growth in a male-pattern distribution, known as hirsutism, which occurs in the majority of patients with elevated DHEA 2
Persistent or treatment-resistant acne should raise suspicion for underlying hyperandrogenism, particularly when occurring beyond typical adolescent years 2
Androgenic alopecia, or male-pattern hair loss with frontal and vertex thinning, indicates significant androgen excess 2
Menstrual dysfunction, including oligomenorrhea or amenorrhea, occurs commonly with elevated adrenal androgens 1, 2
Infertility or difficulty conceiving results from chronic anovulation associated with hyperandrogenism 2
Clitoromegaly, or clitoral enlargement, indicates more severe hyperandrogenism and should prompt urgent evaluation for androgen-secreting tumors 2
Voice deepening is a concerning sign that suggests possible adrenal carcinoma, particularly when DHEAS exceeds 6000 ng/mL 1, 2
Rapid onset virilization, developing over weeks to months, strongly suggests an androgen-secreting tumor rather than PCOS 2

The Endocrine Society recommends investigating for non-classical congenital adrenal hyperplasia when DHEAS is greater than 3800 ng/mL in ages 20-29 or greater than 2700 ng/mL in ages 30-39 1
DHEAS greater than 6000 ng/mL should prompt immediate evaluation for androgen-secreting adrenal carcinoma with adrenal imaging 1
Rapid symptom progression, such as over weeks to months, suggests a tumor rather than PCOS 2
Very high testosterone levels combined with elevated DHEAS indicate possible malignancy 1
Clitoromegaly or voice changes mandate immediate imaging to exclude adrenal or ovarian tumors 1, 2

The American College of Clinical Endocrinologists recommends measuring total and free testosterone, DHEAS, androstenedione, LH, and FSH as the initial hormone panel 1
Liquid chromatography-tandem mass spectrometry (LC-MS/MS) should be used for testosterone measurement when available for highest accuracy 2
Morning samples should be obtained due to diurnal variation in androgen levels 2
17-hydroxyprogesterone should be checked to rule out non-classical congenital adrenal hyperplasia, particularly when DHEAS exceeds age-specific thresholds 1
Prolactin and TSH should be measured to exclude hyperprolactinemia and thyroid disease as alternative causes of menstrual irregularity 2
Fasting glucose and 2-hour oral glucose tolerance test should be performed to screen for insulin resistance and diabetes 2
Fasting lipid panel should be checked to assess cardiovascular risk 2

Adrenal CT scan should be obtained when DHEAS is markedly elevated or when 21-hydroxylase antibodies are negative to evaluate for adrenal tumors 1
Pelvic ultrasound should be performed to assess for polycystic ovaries in females with suspected PCOS 1
Dexamethasone suppression testing should be considered to distinguish functional from neoplastic causes when imaging shows adrenal masses 1
Chemical-shift MRI is highly sensitive for distinguishing benign from malignant adrenal tumors 3
Hounsfield units greater than 10 on unenhanced CT suggest malignancy and warrant contrast-enhanced imaging with washout studies 3
Adrenal carcinoma should be suspected when tumors are greater than 4-5 cm, have irregular margins, or show heterogeneity on imaging 3
