Fig. 3

Follow up computed tomography (CT) detected a marked increase in the size of the supratentorial ventricular system together with clinical symptoms suggestive of hydrocephalus. a-b: Post-surgical changes secondary to a pterional craniotomy and a transsylvian approach, with pneumocephalus and blood remnants in the surgical site. c-d: Plain CT performed at the emergency department 3 months after surgical basilar artery occlusion. The supratentorial ventricular system was markedly increased in size compared to the previous study. We also noticed low attenuation periventricular changes around the lateral ventricles (LVs), thus suggesting transependymal edema. e-f: A right parieto-occipital ventriculoperitoneal shunt was placed, with the proximal catheter arising from the occipital horn of the right LV. Notice the decrease in the size of the supratentorial ventricular system in comparison with the previous study
