Hydrocephalus, yearly follow-up. Compared to CT dated 11/15/2012, there is no significant change in ventriculomegaly involving the lateral, third, and fourth ventricles. There is diminished supratentorial white matter volume particularly the left parieto-occipital and frontal lobes. There is thinning of the corpus callosum. No evidence of recent infarct or hemorrhage. Small chronic blood products involving the dependent portion of the left lateral ventricle are decreased in conspicuity compared to prior MRI. Sulcation appears within normal limits. There is normal myelination pattern. No new mass or mass-effect. No extra-axial collections. Major flow-voids are preserved. Partially empty sella. There is mild nonspecific opacification of the paranasal sinuses. There is a cystic lesion involving the right parietal scalp which may represent a scalp lesion such as sebaceous cyst for example.
1. No significant change in ventriculomegaly involving the lateral, third, and fourth ventricles compared to CT 11/15/2012 compatible with communicating hydrocephalus. 2. Diminished supratentorial white volume and thinning of the corpus callosum.3. Slight decrease in conspicuity of chronic intraventricular blood products.
