Thyroid isthmus agenesis: A rare congenital anomaly
Congenital anomalies of thyroid gland like hypoplasia, ectopic thyroid, hemiagenesis or agenesis of gland are commonly reported in literature. Agenesis of thyroid isthmus is very rare, with only few cases reported and most of them on cadaveric dissection. We hereby report a case with right thyroid colloid goiter, planned for hemithyroidectomy and incidental intraoperative finding of isthmus agenesis.
