During the routine undergraduate dissection of the thyroid gland of a 50 year old male cadaver, multiple anomalies in the morphology and the blood supply of the thyroid gland were encountered. These were in the form of the absence of the thyroid isthmus, the presence of the pyramidal lobe and levator glandulae thyroidae on the right side and the bilateral absence of the superior thyroid artery, the gland being supplied solely by the inferior thyroid arteries which came out as the branches of the thyrocervical trunk. Agenesis of the isthmus can be associated with other types of dysorganogenesis, such as the absence of a lobe or the presence of ectopic thyroid tissue and hence, in clinical practice, when such a condition is diagnosed, it is necessary to perform a differential diagnosis against other pathologies such as autonomous thyroid nodule, thyroiditis, etc. The knowledge of various developmental anomalies of the gland and the variations in the neurovascular relations helps the surgeon in the better planning of a safe and effective surgery.
