The left first rib has been resected 3.2 centimetres beyond the costotransverse joint. There is again elongation of the left C7 transverse process. A possible persistence of a fibrous band then extends anteroinferiorly from the tip of the transverse process to pass posteriorly and to the left subclavian artery. Mild asymmetric thickening and hyperintensity of the C8 and T1 nerve roots on the left persists. The C8 nerve root from the foramen to the level of this fibrous band has a mildly tortuous course.
Conclusion: Possible persistence of the fibrous band extending anteroinferiorly from the inferior tip of the left C7 transverse process with distortion of the course of the left C8 nerve root. C8 and to a lesser extent T1 nerve roots remain thickened and mildly hyperintense.
