Abstract
Thyrotoxicosis as a clinical entity has varied aetiologies. Accurate distinction of the underlying aetiology is important to guide therapy. Clinical findings are not always accurate in identifying the underlying aetiology. There is considerable overlap between the various aetiologies when using serum T3/T4 ratio. Although ultrasound is widely available and has reasonable sensitivity, it is operator dependent and misses many cases of early Grave's disease. 99mTc scintigraphy is a simple and accurate modality for assessing the functional status of the thyroid gland and delineating the aetiology of thyrotoxicosis. This paper seeks to inform on the use of thyroid scintigraphy in the management of benign thyroid disorders.

Highlights
The thyroid gland, a small but important endocrine organ, which is usually located in the anterior neck, functions to synthesise, store and secrete the thyroid hormones thyroxine and tri-iodothyronine
SarfoKantanka et al have reported that thyroid disorders are the second leading cause of endocrine morbidity in central Ghana with hyperthyroidism accounting for 9.2% of all cases seen in their endocrine service.[3]
The same authors have reported that toxic multinodular disease is more common than thyrotoxicosis from diffuse goitre in Ghana.[4]
