Noonan's Syndrome with Syringomyelia

Abstract: A case of Noonan's syndrome with cervical syringomyelia is presented here representing the second reported instance of such association. A CT of metrizamide myelography revealed a high density in the middle subintradural space in the cervical region below C2. Sensory dissociation was minimal and localized in the left C4. It could not be determined whether this association between syringomyelia and Noonan's syndrome is related or represents a chance.
