Presentation
CT performed for headache demonstrated an abnormality.
Patient Data
Obstructive hydrocephalus with enlarged ventricles and outward bowing of the third ventricular recesses and elevation and thinning of the corpus callosum. The aqueduct is not definitely patent and may be the site of obstruction.
Compared to the prior study the ventricles are now slitlike. There are bilateral acute/subacute subdural hemorrhages. No associated brain shift. The corpus callosum is swollen and of low attenuation.
Features are over-shunting and post-hydrocephalus corpus callosum damage.
The variable shunt-valve settings were changed with resolution of the subdural hemorrhages on follow-up CT studies (not shown).
The corpus callosum is gliotic with scalloping of its upper border. Ventricles remain small but are no longer slit-like and the subdural collections have resolved.
Case Discussion
Typical demonstration of the changes seen in post-hydrocephalus corpus callosum damage.
