Thyroidea ima — when the inferior thyroid artery arises proximal to its expected thyrocervical trunk origin, whether from the aortic arch or from the subclavian artery, that's what you call it. In this case, the thyroidea ima artery arises from the first part of the right subclavian artery next to the origin of the right common carotid artery (black arrowheads).
The right vertebral artery is also demonstrated (red arrows).
