History of neuroblastoma. In remission. Rule out relapse. There is no acute infarct or intracranial hemorrhage. There is no space-occupying brain lesion, midline shift or herniation. Tiny focus of T2/FLAIR hyperintensity in the deep left posterior left temporal white-matter is unchanged. The ventricles and other CSF-containing spaces are normal in size. Following contrast administration, there is no abnormal brain or leptomeningeal contrast enhancement. Major intracranial vascular flow voids are preserved. The pituitary gland is unremarkable. There is moderate left maxillary mucosal thickening.. There is mild ethmoid and maxillary sinus mucosal thickening. These findings are nonspecific. The mastoid air cells are clear. The palatine tonsils are prominent, right more than left. This is a fairly common finding in this age group and is usually reactive. There is asymmetric increased contrast enhancement in the left hemiglossus and the included left parotid gland. There is also asymmetric fatty signal in the marrow in the left side of C1 and C2 vertebrae. These findings are probably related to previous radiation treatment. There is no destructive osseous lesion.
1.There is no intracranial mass or abnormal enhancement to suggest metastasis.2.Posttreatment changes in the face are partially included. Please refer to the report of the CT scan of the neck from the same day for details.
