Redemonstration of right transparietal ventricular shunt catheter terminating in the right lateral ventricle and connected extracranially to an unchanged right parietal subdural catheter. No intracranial hemorrhage is identified. There is no significant residual subdural fluid in the right convexity. No midline shift. There is decrease in caliber of the markedly dilated lateral and third ventricles. The lateral ventricles now measure 9.9 cm versus previously 12.3 cm transverse in the axial plane. There is corresponding increase in the caliber of the cortical mantle. In the axial plane the right cerebral mantle measures 30 mm and the left measures 29 mm, versus previous measurements of 18 mm and 16 mm, respectively. At the vertex, the left cortical mantle appears thicker than the right, consistent with previous exam. The fourth ventricle appears normal in caliber. The septum pellucidum is again noted to be absent. There is persistent downward mass-effect on the posterior fossa. There is limited visualization of the foramen magnum due to regional streak artifact although there appears to be some degree of soft tissue fullness. The caudal extent of the cerebellar tonsils are beyond the field of view.
