Abstract：ObjectiveTo explore the diagnostic features of normotensive primary aldosteronism (PA). MethodsThe clinical data of a normotensive PA patient admitted to the Department of Endocrinology of the Third Affiliated Hospital of Sun Yat-sen University on May 4,2018 were analyzed retrospectively and literatures were reviewed. ResultsA 39-year-old female patient was hospitalized because of 3-year limb weakness and numbness, and 2day deterioration. The patient presented normotension,hypokalemia (2.10mmol/L), high aldosterone level (465.83pmol/L) and low rennin level (2.90ng/L). CT scan displayed a right adrenal cortical adenoma (23mm×18mm). The patient was diagnosed with PA eventually. Interestingly, the blood pressure was normal during the whole period. ConclusionNormotensive PA should be considered when a patient presents hypokalemia paralysis without hypertension.
