NAT/TBI with bilateral subdural shunts. There are bilateral subdural shunt catheters with associated hardware that create substantial artifacts that obscure portions of the brain. Within this limitation, there are bifrontal subdural fluid collections, measuring up to 15 mm in thickness on the left and 9 mm on the right, with a few septations. There is flattening of the underlying brain parenchyma. There also appears to be areas of volume loss and high T2 signal in the bilateral anterior frontal lobes. The ventricles appear somewhat prominent, perhaps due to artifacts. There is marked thickening of the frontal calvarium. The orbits are unremarkable.
