 There is no suspicious intracranial enhancement, acute infarct, mass effect, or cerebral edema. There is moderate soft tissue crowding at the foramen magnum with slightly pointed cerebellar tonsillar morphology, without true peg-like appearance. There is a single small nonenhancing white matter T2 hyperintense signal abnormality in the right frontal white matter, nonspecific. There is punctate focus of susceptibility effect in the left basal ganglia, nonspecific probably representing calcification. There is mild to moderate volume loss.There is no hydrocephalus. There is no midline shift or herniation. There is a mucus retention cyst in the right maxillary sinus. There is a small nonenhancing rounded lesion in the scalp by the vertex of the skull which is nonspecific, and likely representing a small sebaceous cyst. The skull and extracranial soft tissues are otherwise unremarkable.
1.No intracranial mass, mass effect or suspicious enhancement.2.Moderate soft tissue crowding at the foramen magnum with slightly pointed cerebellar tonsillar morphology, but not fitting the strict criteria for Chiari I malformation. Clinical correlation is advised.
