Neurofibromatosis type I. Mid thoracic pain. Please assess for paraspinous humerus. There is a mild but focal leftward convex curvature centered at T2. Alignment is otherwise anatomic. There is a mild deformity of the T2 vertebral body, where it appears scalloped along its right lateral aspect with minimal asymmetric height loss. There is no soft tissue mass to explain the scalloping. The soft tissue along this region is, however, heterogeneously T2-hyperintense. A similar but more mild deformity also affects the T1 vertebral body.Otherwise, the vertebral body heights are preserved. The other thoracic vertebrae are of normal morphology. There is no suspicious marrow abnormality. The disks heights are preserved as well as their T2 signal.The spinal canal and the neural foramina are preserved.Thoracic spinal cord shows normal signal and shape. On the coronal images, there is mild thickening of the lower cervical nerve roots which is suggestive of small nerve root neurofibromas. T2-hyperintense small but elongated masses just posterior to the common carotid/internal jugular veins at the root of the neck may represent small neurofibromas (or less likely lymph nodes). A left paraspinal T2-hyperintense nodule that measures 5 mm anterior to the neural foramen at T2-T3 level may represent a dilated lymphatic channel or a small neurofibroma. There is no paraspinal mass. However, the study was performed without intravenous contrast and there was minimal motion.
1.Minimal T2 vertebral body deformity associated with mild but focal leftward convex curvature may relate to mesenchymal dysplasia of NF1 or resected paraspinal neurofibroma or lateral meningocele, if there is compatible clinical history.2.Mild thickening of the lower cervical nerve roots probably reflects nerve root neurofibromas. Other findings are also present including soft tissue nodules at the root of the neck as well as a 5 mm nodule anterior to the left T2-T3 neural foramen as described above. These may represent additional neurofibromas as described above.
