Abstract
ABSTRACT
Thyroid gland is the largest of all endocrine glands. It is composed of two lobes.
These two lobes are joined by an isthmus and this resemble the letter “H”. A wide
range of morphological variations and developmental anomalies of the thyroid
gland like hypoplasia, ectopy, hemiagenesis, and agenesis have been reported in
literature. Out of these, the incidence of agenesis of the thyroid isthmus is rare,
and very few cases have been reported. In our report, 28 year old male patient was
found with agenesis of thyroid isthmus with papillary carcinoma in the right lobe of
thyroid. During the operation it was seen that the right and left thyroid lobes were
independent from each other and isthmus was absent. We will present a case of
thyroid isthmus agenesis and discuss the clinical importance and the incidence of
this case.
