A 49-year-old lady presented with recurrent renal stones and bone pains for 5 years. On evaluation, she was found to have raised serum calcium—11.2 mg/dL, intact parathyroid hormone (PTH), and low serum phosphorus with adequate 25-OH vitamin D. So, a biochemical diagnosis of primary hyperparathyroidism (PHPT) was established. Ultrasound of the neck showed a well-defined, oval-shaped, hypoechoic heterogeneous lesion (9.8 × 12.4 × 28.3 mm) noted at the posteroinferior side of the left thyroid lobe. The lesion shows peripheral vascularity and a feeding artery (polar vessel sign) suggestive of parathyroid adenoma (PA). “Polar vessel sign” is a characteristic ultrasound feature of PA and may help to identify the same in equivocal cases.
