title: Hypokalemic periodic paralysis in primary hyperaldosteronism. Subclinical myopathy with atrophy of the type 2A muscle fibers.
abstract: A case of a patient suffering from primary hyperaldosteronism is reported. In this case the disease is manifested clinically by periodic paralysis and hypopotasemia without permanent myopathy. The morphological study of the muscle demonstrates selective atrophy of the type 2A fibers as the most pronounced alteration. These findings suggest a chronic myopathic process.
