Periodic paralysis: an uncommon complication of primary aldosteronism

RESUMO

Periodic paralysis is an uncommon complication of primary aldosteronism in the non-Asian population. We describe the case of a Brazilian woman who presented to the emergency room with proximal symmetric tetraparesis that was later diagnosed as primary aldosteronism. This case report shows that primary aldosteronism should be included in the differential diagnosis of periodic paralysis, especially among hypertensive patients.
