Male, 11 years old, with behavioral outburst spells. Evaluate for site of worsening focal seizure. A left frontal approach ventricular shunt catheter is demonstrated with its tip in stable position in the vicinity of the foramen of Monro. The left lateral ventricle is decompressed. The right lateral ventricle remains somewhat patent but with a wavy irregular contour and areas of periventricular T2 hyperintensity suggesting gliosis. The third ventricle is decompressed, and the fourth ventricle is normal. There has been no significant interval change in size or configuration of the ventricular system.Volume loss, particularly of the white matter, and dysmorphism of the right cerebral hemisphere are unchanged from prior. The corpus callosum remains thinned uniformly. No new parenchymal lesions are seen. No evidence of parenchymal edema or mass effect is detected. No abnormal extra-axial collections are detected.
1.Stable size and configuration of the shunted ventricular system.2.Stable generalized dysmorphism of the right cerebral hemisphere. No new parenchymal lesions are detected.
