Nodular thyroid disease

Nodular thyroid disease is common. Ultrasound examination of the neck for a variety of reasons has revealed a linear increase in the prevalence of thyroid nodules from negligible at 15 years to 50% by the age of 60. Only 10% of these nodules are palpable by experienced examiners. Conversely, 50% of patients referred to a thyroid clinic with an apparently solitary thyroid nodule will be found to have a multinodular goitre.
