1. Prominent veins in brain death.
Prominent veins in brain death. This 8-year-old boy was ejected in a motor vehicle crash and sustained severe TBI with an initial GCS score of 3, nonreactive pupils, and markedly elevated intracranial pressure despite aggressive treatment. Anteroposterior view of nuclear medicine brain scan 5 days later (A) demonstrates decreased but not absent cerebral blood flow as evidenced by activity in the superior sagittal sinus. MR imaging was obtained 11 days later. Axial SWI (B) shows scattered small hypointense hemorrhages (arrows) in the subcortical white matter and corpus callosum, consistent with shearing injuries. In addition, there are prominent deep medullary veins (open arrows) throughout the bilateral hemispheres. He subsequently met clinical criteria for brain death and was taken off ventilatory support 2 weeks after admission.
