Abstract
Acquired primary hypothyroidism in infancy can be related to autoimmune thyroiditis and can present with unusual symptoms, such as muscle pseudohypertrophy and pituitary tumor. This condition can cause permanent deficits in psychomotor development and growth despite adequate replacement with L-thyroxine.
