Right-sided hemiagenesis of the thyroid lobe and isthmus: A case report.

Tiwari PK, Baxi M, Baxi J, Koirala D - Indian J Radiol Imaging (2008)

Bottom Line: Hemiagenesis of the left lobe is far commoner than of the right.Clinically, these patients may be euthyroid, hyperthyroid, or hypothyroid.Ultrasonography is usually able to diagnose this condition easily, as we demonstrate in this case report of a 37-year-old lady with an incidentally detected thyroid nodule who was found to have hemiagenesis of the right lobe and isthmus.

ABSTRACT
Unilateral or bilateral hypoplasia or agenesis of one or both thyroid lobes, with or without isthmic agenesis, is a rare developmental anomaly. Hemiagenesis of the left lobe is far commoner than of the right. Clinically, these patients may be euthyroid, hyperthyroid, or hypothyroid. Ultrasonography is usually able to diagnose this condition easily, as we demonstrate in this case report of a 37-year-old lady with an incidentally detected thyroid nodule who was found to have hemiagenesis of the right lobe and isthmus.

Figure 0002: Transverse USG image shows agenesis of the right lobe

Mentions: Free T3, free T4, and TSH on two occasions suggested a biochemically euthyroid state. USG showed multiple hypoechoic to isoechoic heterogeneous nodules [Figure 1] in the enlarged left lobe, the largest being 6.6 mm in diameter. Doppler showed increased vascularity in the left lobe. The isthmus and right lobe were not visualized [Figure 2]. CT scan of the neck and thyroid confirmed the agenetic right lobe and isthmus [Figure 3]. Fine needle cytology of the thyroid nodule showed a colloid nodule with cystic degeneration and hemorrhage.
