Primary aldosteronism with hypokalemic rhabdomyolysis: a case report and review of the literature.

Background: Hypokalemic rhabdomyolysis is a rare clinical manifestation of primary aldosteronism, making its diagnosis challenging, particularly when it becomes the primary presenting symptom. Herein, we present a case of primary aldosteronism with hypokalemic rhabdomyolysis and conduct a related literature review. Case presentation: We report the case of a 54-year-old Chinese male patient who presented with intermittent weakness over the past year and was admitted with sudden limb paralysis for 2 days. The final diagnosis was primary aldosteronism accompanied by hypokalemic rhabdomyolysis syndrome. By reviewing the related Chinese and English literature, we noticed that only a few cases were published since 1978. After excluding irrelevant literatures, we summarized and analyzed 43 patients of with primary aldosteronism accompanied by hypokalemic rhabdomyolysis syndrome. All patients showed good recovery, with normalized blood potassium levels, and a majority achieved normalized blood pressure. Some patients still required medication for blood pressure control. Conclusions: Primary aldosteronism rarely causes rhabdomyolysis; the occurrence of severe hypokalemia and rhabdomyolysis should prompt consideration of primary aldosteronism in the differential diagnosis. Early detection and treatment are crucial for determining patient prognosis. [ABSTRACT FROM AUTHOR]
