Aim: The aim of our study was to assess the limitation of clinical examination in determining the morphology of thyroid gland in patients with hyperthyroidism and its implications.
Methods: A retrospective analysis of consecutive patients with hyperthyroidism seen in a tertiary endocrine clinic were analyzed. Sub-analysis was performed on patients with proven Graves' disease.
Results: Of the 133 patients included in this study with hyperthyroidism, 60 (45%) patients had significant nodularity on ultrasound (US). However, only 67% of these were identified on clinical examination. In patients with confirmed Graves' disease (n = 73), the discordance between US and clinical examination was very similar (18 of 30 patients, 60%).
Conclusion: US should form an essential part of the evaluation of hyperthyroidism as the morphology of thyroid gland could be variable and nodules in these glands would also need to be appropriately investigated. This would also significantly influence decision-making and appropriate immediate and follow-up management plan.
