%X Primary aldosteronism (PA) is the most frequent form of secondary endocrine hypertension, which is characterized by excessive aldosterone secretion and suppressed renin. The currently recommended diagnostic algorithm is very clear, and the plasma aldosterone-to-renin ratio (ARR) is considered the first-line screening test. However, this indicator is influenced by many factors, some of which may cause false-negative results, consequently leading to underdiagnosed PA. Here, we report the rare case of a 38-year-old man who presented with bilateral accessory renal arteries and aldosterone-producing adenoma but had a negative ARR test result.
