Abstract

Hashimoto's thyroiditis, also called chronic lymphocytic thyroiditis, is the most common cause of acquired hypothyroidism in children and adolescent. Children may present with an euthyroid goiter, subclinical hypothyroidism, overt hypothyroidism, and, rarely hyperthyroidism. A 14-year old girl presented with abrupt onset headache, nausea and vomiting. Her blood pressure was high. Laboratory studies demonstrated a high thyroid hormone level with elevated anti-thyroglobulin antibody and anti-microsomal antibody titer, but a normal thyrotropin receptor antibody. (123)I scan showed a normal uptake. The extensive investigations to exclude other causes of hypertension showed no abnormality. We report an unusual presentation of Hashimoto's thyroiditis with severe thyrotoxicosis.
