Evaluate ventriculoperitoneal shunt. Nonenhanced head CT:Examination demonstrates a right-sided ventricular catheter entering from the right paramedian high convexity frontal lobe, traversing the right frontal lobe, entering the dilated right frontal horn, traversing the midline and the tip in the left dilated frontal horn. The position of the shunt has not change since prior head CT.Dilated supratentorial ventricular system is again noted. Compared to prior MRI and head CT no definitive appreciable interval change.Periventricular low-attenuation white matter a similar to increased signal intensity noted on prior MRI.No evidence of intracranial hemorrhage, edema or midline shift.
1.Dilated supratentorial ventricular system with no appreciable interval change since prior exam.2.No change in position of right-sided ventricular catheter.3.No evidence of any new acute intracranial findings.
