Relapsed neuroblastoma, pre-NANT 11-01. Orbits: There has been near resolution of the anterior and central skull base tumor with mild residual enhancement along the left lesser wing of the sphenoid and sphenoid roof, without appreciable mass effect upon surrounding structures. There is persistent focal T2 hyperintensity in the canalicular and posterior orbital portions of the left optic nerve. The right orbit is unremarkable. Brain: There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. 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 previously described right occipital bone region finding is unchanged and may be related to the lambdoid suture. There is a small amount of residual scattered paranasal sinus mucosal thickening.
1. Near resolution of the anterior and central skull base tumor with mild residual enhancement along the left lesser wing of the sphenoid and sphenoid roof, without appreciable mass effect upon surrounding structures.2. Persistent focal T2 hyperintensity in the canalicular and posterior orbital portions of the left optic nerve may be related to prior compressive neuropathy. 3. Decreased pansinus mucosal inflammation.
