Abstract
A wide range of morphological and developmental variations of thyroid gland like hypoplasia,
ectopic thyroid tissue, hemiagenesis or agenesis of thyroid gland has been reported. Out of these
agenesis of the thyroid isthmus is a very rare congenital anomaly. Thyroid isthmus agenesis does not
manifest clinical symptoms, and it can be confused with other thyroid pathologies. Also the presence
of levator glandulae thyroideae and its anatomical variations gain importance in the pathologies
which are related to thyroid gland and their treatment modalities. We hereby, report the absence of
isthmus and presence of levator glandulae thyroideae and pyramidal lobe in a middle aged male
cadaver. The present case report is an attempt to highlight the implications of variation of thyroid
gland from diagnostic, phylogenetic and functional perspectives.
