NF1 and persistent headaches. There is an enhancing mass in the right spinal canal at the C3-4 level that measures 12 mm in diameter. There are numerous skin nodules. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are minimal nonspecific cerebral white matter T2 hyperintense foci. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and paranasal sinuses are grossly unremarkable. There appears to be a small Thornwaldt cyst.
1. No evidence of intracranial hemorrhage, mass, or acute infarct. 2. A mass in the right spinal canal at the C3-4 level that measures 12 mm in diameter likely represents a neurofibroma.3. Numerous skin nodules also likely represent neurofibromas.
