16 years, Male, follow-up contusion. Diffuse traumatic brain injury. There are areas of T2 hypointensity with susceptibility involving the right anterior inferior frontal lobes centered on the gyri recti consistent with contusion and similar to recent CT head. There is surrounding edema and minimal local mass effect. There is also minimal extra-axial T2 hyperintensity along the bilateral frontal cerebral convexities without suppression on the FLAIR sequence suggesting minimal subdural fluid.No midline shift or herniation. No hemorrhage is seen elsewhere in the brain. No evidence of ischemia, intracranial mass, midline shift, or herniation. Ventricles remain normal in size. Major flow-voids are preserved. Remainder of the brain is unremarkable. Calvarium and extra cranial soft tissues are grossly unremarkable.
Bilateral frontal lobe contusions with surrounding edema similar to recent CT allowing for differences in technique. Minimal subdural fluid/blood products also suspected along the frontal convexities without mass effect. No evidence of traumatic injury elsewhere in the brain.
