An anomalous artery was seen arising from the arch of aorta and coursed upwards to the isthmus of thyroid gland. In the same cadaver, on further exposure of blood vessels supplying the thyroid gland, it is observed that the left inferior thyroid artery was absent. Though the incidence of thyroid ima artery arising from brachio cephalic trunk and subclavian artery was reported earlier, this is a rare finding where the artery arose from arch of aorta with absence of left inferior thyroid artery.
