Right C1-C2: increase in nerve root sheath enhancing mass, previous 18 x 8 mm, current26 x 9 mm.
Cervicothoracic junction: 2 enhancing intra-axial lesions without cord compromise.Unchanged.Cervical intrathecal extra-axial enhancing lesions- C6 - a dumbbell lesion extending along C6 nerve root sheath: previous 10 x 11 mm,current 12 x 10 mm with appearances suggesting a slight increase in size and furtherdisplacement of the cord without cord signal change or enhancement. The nerve rootsheath extension is of similar appearance through the left foramen.
Right submandibular: previous 31 x 16 axial increasing to 38 x 21 mm with increase ofa mild degree to the subcutaneous nodules superior to this.Bilateral carotid sheath: unchanged.
Bilateral brachial plexus: unchanged noting the extension into the right lung apexregion.Right posterior triangle: unchanged.
Paraspinal muscles: slight increase in number and size.
Thoracic cord nodular enhancement: slight increase in thickness.
Thoracic intradural extra-axial nodules: slight increase in nodule size with dominantL1 nodule changing from April 11 22 x 12 mm, December 11 22 x 15 mm and current 26 x18 mm
Other sites: right intercostal, right subclavian, right paravertebral upper thoracic,subcutaneous and intercostal regions: slight increase in size - difficult to quantify.
Paraspinal enhancing nodule T5: previous 11 mm, current 12 mm.Syrinx T3-T4: unchanged.
Thoracolumbar region: cord expansion - known astrocytoma: unchanged.
Cauda equina - multiple enhancing nodules: unchanged.Lumbosacral plexus - plexiform neuroma: slight increase in size .Right parauterine enhancing lesion: previous 38 mm width,
