Reason: Please evaluate C1 lesion and if there are other paraspinal masses History: mass in right neck. MRI Cervical Spine:There is a soft tissue abnormality of the left C3 nerve root that is hyperintense on STIR images, causing expansion of the left C2-C3 neural foramen, extending to the C1-C2 level, representing neurofibroma. The lesion extends also posteriorly into the deep neck musculature. There is subtle neural foraminal asymmetry on STIR images, left greater than right, at the C4-C5, C5-C6, and C6-C7 levels, without evidence of discrete measurable mass.The cranial-cervical junction is normal. There is normal cervical lordosis. The cervical spine alignment is anatomic. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The signal of the visualized cord is normal. The epidural space, thecal sac, and spinal cord are preserved with no evidence of spinal canal/neural foraminal narrowing. The intervertebral discs demonstrate normal T2 intensity and height with no evidence of disc herniation. There is no evidence of abnormal enhancement of the spinal cord.There are partially imaged plexiform neurofibromas of the right lateral supraclavicular fossa region. Redemonstrated are T2 hyperintense foci in the cerebellum, left greater than right, which is better demonstrated on prior MRI.MRI Thoracic Spine:There is normal thoracic kyphosis. The vertebral bodies, marrow and end plates demonstrate a normal MR appearance. The epidural space, and thecal sac, are preserved with no evidence of spinal canal narrowing. Normal signal of the spinal cord is noted throughout. The intervertebral discs demonstrate normal T2 intensity and height with no evidence of disc herniation. The paraspinal soft tissues are unremarkable. No evidence of kyphoscoliosis or discrete masses. The conus terminates at L1-L2.
