Chronic subdural hematoma. Three-month follow-up. Evaluate for changes. The bilateral apical frontal subdural fluid collections are significantly smaller. The residual effusions are limited medially to the frontal parafalcine region and measures less than 5 mm in thickness. The associated susceptibility effect on the previous examination has nearly resolved. There is no mass-effect on the underlying brain. The posterior fossa subdural hematomas have resolved. There is focal parenchymal volume loss and T2 hyperintensity involving the right postcentral gyrus and to a lesser extent the anterior aspect of the superior parietal lobule. There are small patches of occipital and temporal white-matter T2 hyperintensity. The degree of myelination is otherwise appropriate for age. There is no mass-effect or midline shift. There is mild prominent of the subarachnoid spaces, particularly in the frontal regions. The ventricles are unchanged in size. There is no gross orbital abnormality. There is minimal left mastoid T2 hyperintensity, which is nonspecific.
1.Right parietal encephalomalacia is probably reflective of prior insult. Small patchy areas of high T2 signal in the white matter of the occipital and temporal lobes are non-specific and may represent terminal zones of myelination, for example.2.The cerebral convexity subdural effusions are much smaller and cause no significant mass-effect. The posterior fossa subdural hematomas have resolved.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
