(a) Axial T1 weighted MR of the brain without contrast through the level of the external auditory canals demonstrates absence of the left external ear and external auditory canal (thin white arrow). There is also absence of the left internal carotid artery (thick yellow arrow). The right internal carotid artery is shown for comparison (thin yellow arrow). (b) Axial postcontrast CT of the neck at the level of the thyroid gland shows a normal right thyroid lobe (thick white arrow) with absence of the left thyroid lobe (thin white arrow). (c) Axial noncontrast time of flight MRA of the brain demonstrates a normal right internal carotid artery at its petrous segment (thin white arrow). There is absence of the left internal carotid artery (thick white arrow). (d) Three-dimensional reformation of the MRA of the brain demonstrates a normal right internal carotid artery (thin white arrow). The left internal carotid artery is absent.
