Sagittal MR images of thoracolumbar spine: a pre-treatment STIR demonstrates the lesion at T12 with extension through the anterior vertebral body bony margin; b pre-treatment T2 demonstrates tumour projecting into the T12 prevertebral soft tissue (arrowhead) and into the neural foramen at L1 (long arrow); and c post 3 cycles of pembrolizumab, there is no longer prevertebral extension of tumour at T12 (arrowhead) and only ill-defined soft tissue remains around the L1 root (long arrow); lesions in the body of L1, L4 and L5 are also smaller
