A 9-month-old boy with paravertebral dumbbell neuroblastoma. a Sagittal T2-weighted fat-saturated MR image shows a large soft tissue mass occupying and expanding the spinal canal from T12 to S3 levels (arrows), also causing compression of the spinal cord. b Axial T1 post-contrast imaging reveals a large right paravertebral mass (arrows) with intraspinal extension, occupying the entire right-sided neural foramen. Urgent spinal laminectomy and decompression was subsequently performed
