*Corresponding author: Ivan P. Mani* and Niharika Raju


Agenesis of the thyroid isthmus is a rare entity with a incidence rate of 0.5 and 10%. Thyroid isthmus agenesis could be associated with ectopic thyroid tissue or agenesis of the thyroid lobes. We discuss a case of a multinodular goitre which presented with morphological variations which was not detected on ultrasonography of the neck.
