Female, 17 years old, with Neurofibromatosis type I, with back pain and multiple intracranial findings of NF1. Brain and orbits:Mild patchy T2 hyperintensity is again seen in the bilateral thalami, as well as questionably in the pons and left basal ganglia, showing no significant interval change. T2 hyperintensity of the medial temporal lobes including the hippocampi is also unchanged. Gyriform cortical T2 hyperintensity within the paramedian posterior left frontal lobe is unchanged as well.No new areas of parenchymal signal abnormality are detected. No pathologic parenchymal or extra-axial enhancement is observed. There are no findings to suggest intracranial hemorrhage or any abnormal extra axial fluid collection. The ventricular system is normal in size and morphology.Redemonstrated is asymmetric thickening of the right optic chiasm and right prechiasmatic optic nerve. The intraorbital optic nerve does not appear to be involved. There is no associated pathologic enhancement. Findings are unchanged.Cervical and thoracic spine:Spinal alignment is anatomic. Vertebral body height and morphology are within normal limits. No pathologic marrow replacement or marrow edema is seen.Visualized spinal cord shows normal signal intensity and morphology throughout. No pathologic intraspinal enhancement is observed.Spinal soft tissues are unremarkable.The intervertebral discs are preserved. No significant bulge or herniation is seen. The spinal canal and neural foramina remain patent.
1.Stable appearing optic pathway glioma involving the right optic chiasm and right prechiasmatic optic nerve.2.Stable scattered foci of abnormal signal intensity in the brain which are nonspecific but likely related to NF1. No new intracranial lesions are seen.3.Unremarkable evaluation of the cervical and thoracic spine.
