Unusual presentations of hypothyroidism.
Hypothyroidism is a commonly diagnosed endocrine disorder. Typical signs and symptoms of hypothyroidism include lethargy, cold intolerance, hoarseness, dry skin, constipation, delayed relaxation phase of deep tendon reflexes, and bradycardia. Hypothyroidism, presenting with such classic manifestations, usually is readily recognized and, therefore, easy to diagnose. Occasionally patients have less commonly emphasized symptoms, making the diagnosis less apparent. Such atypical presentations may suggest other diseases as the primary problem and, therefore, the initial focus of attention is on a diagnosis other than hypothyroidism. We have observed patients with hypothyroidism with rare manifestations. The diagnosis of primary hypothyroidism was established in all patients by thyroid function tests, and initiation of thyroid hormone therapy resulted in significant improvement of the presenting symptom. We considered it instructive to report about these patients because it shows the need to be aware of the unusual presentations of hypothyroidism and to consider hypothyroidism when confronted with atypical clinical manifestations.
