title: [Hypothyroid myopathy. Communication of 4 cases].
abstract: We report four patients with primary hypothyroidism (3 female, aged 47, 46, 49 and 34 years old) whose principal manifestation was muscle involvement. The diagnosis was oriented by the finding of myoedema and a slow relaxation phase of tendon reflexes. In one patient, an electromyographic and histological study was performed. Thyroid substitution lead to an improvement in myopathy in all patients.
