Incidence of adrenal masses eventually discovered in patients screened for primary aldosteronism.

Context: Biochemical screening for endocrine hypertension may be complex; the known presence of an adrenal mass markedly increases the pre-test probability for adrenal hypertension and may inform diagnostic efforts.

Objective: Model the potential incidence of adrenal masses that may be detected by routine adrenal imaging in patients with suspected endocrine hypertension.

Design: Retrospective cohort study.
