title: Primary hyperparathyroidism simulating motor neuron disease: case report.
abstract: We report a case of a 26-year-old man who presented a lower motor neuron syndrome due to hyperparathyroidism. Electromyography showed neurogenic features with normal nerve conduction studies. Hypercalcemia led to the discovery of a primary hyperparathyroidism with gland hyperplasia. Following parathyroid surgery there was recovery of the neurological symptoms.
