An incidental finding of the thyroidea ima artery : a case report study

الملخص EN

We are here reporting a case of an incidental finding of the thyroidea ima artery emerging from the brachiocephalic trunk with a typical inferior thyroid vessels on both sides emerging from the thyrocervical trunk.

The thyroidea ima artery entered the thyroid gland near to right side of the isthmus from the lower border approximately 1 cm below the normal inferior thyroid.

It arose from the brachiocephalic artery proximal to its bifurcation.

It ran deep to the infrahyoid muscles, giving off a branch that run downward to the superior mediastinum, and then supplying the anterior surface of the isthmus and the right lobe of the thyroid gland by means of two branches.
