MRI with contrast agent from October 2017. Soft tissue formation (13 mm x 9 mm x 13 mm) at the commissura anterior of the vocal cord on the left with contrast enhancement and diffusion restriction, showing the recurrent tumor, approximately the same size as in previously performed CT. Additionally, there is a bilateral swelling of the vocal cords, caused by the tumor with progressive narrowing of the airways in comparison to the previously performed CT. Lymph nodes increased in number and borderline in size in Level 1b, 2, and 3 on both sides.
