Abstract

Thyroid hemiagenesis is one of the rarest congenital anomaly of thyroid gland and found a total of 256 cases reported with female predominance. The left lobe is more commonly seen with thyroid hemi agenesis than the right lobe, with a ratio of 3.6: 1. We hereby reported a case of 50 years old female with the agenesis of the right lobe and isthmus of thyroid gland. Thyroid hemiagenesis can be associated with hyper or hypothyroidism. In our case patient had normal thyroid function tests. On ultrasonography of neck, a large heterogeneous lesion measuring 8.0×4.0×8.0 cm noted in the anterior aspect of neck, predominantly on the right side and seen crossing midline to the left. In our case we detected thyroid hemiagensis incidentally with the help of ultrasonography and confirmed it intra-operatively. Ultrasonography is the most cost-effective means of diagnosing thyroid hemiagenesis.
