 This exam is mildly degraded by motion artifact. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are no areas of abnormal parenchymal signal. There is mild prominence of the ventricles and extra-axial spaces. There is no midline shift or herniation. There is asymmetric prominent T2 and FLAIR hyperintensity within the right transverse sinus, without susceptibility or diffusion restriction. The remainder of the major cerebral flow voids are intact. The skull, paranasal sinuses, and scalp soft tissues are unremarkable. The midline structures and craniocervical junction are within normal limits.
1.Mildly motion degraded exam without evidence of mass, acute infarct, or structural abnormality. 2.Findings compatible with benign external hydrocephalus, a finding that should resolve by 2 years of age. Follow-up imaging may be obtained as clinically indicated.3.Apparent asymmetric signal within the right transverse sinus is likely artifactual relating to differential venous flow, however, an MRV or contrast-enhanced MRI to exclude the possibility of thrombus.
