Signal hyperintensity of the callosum after ventriculoperitoneal shunting.
نویسنده
چکیده
A 66-year-old man underwent ventriculoperitoneal shunting for communicating hydrocephalus. MRI 10 months postoperatively, done for transient headache, showed new fluid-attenuated inversion recovery/T2 hyperintensities within the corpus callosum (figure), while examination revealed improved gait and bladder control with no evidence of a callosal disconnection syndrome.

[Corpus callosal signal changes in patient with obstructive hydrocephalus after ventriculoperitoneal shunting].
BACKGROUND AND PURPOSE Few reports have documented signal abnormalities within the corpus callosum on MR studies obtained after ventricular decompression in patients with hydrocephalus. Our purpose was to establish the frequency of this finding in shunted patients and attempt to elucidate its cause and clinical significance. METHODS All patients with hydrocephalus shunted between 1989 and 199...
متن کاملSuccess rates and complications of ventriculoperitoneal and ventriculoatrial shunting: A systematic review
Background and Aims: The insertion of ventriculoperitoneal (VP) and ventriculoatrial (VA) shunts is the first-line treatment of patients with hydrocephalus and normal-pressure hydrocephalus. The provision of a safety profile for shunting in the treatment of hydrocephalus patients is very important. This study aimed to determine the success rates and complications of VP and VA shunting in patien...
متن کاملFunctional magnetic resonance imaging before and after ventriculoperitoneal shunting for hydrocephalus--case report.
A 70-year-old man with hydrocephalus was examined with functional magnetic resonance (fMR) imaging before and after ventriculoperitoneal shunting. Preoperatively, activation by right hand exercise revealed only a slight signal increase in the peri-rolandic area. However, 3 months after ventriculoperitoneal shunting, a significant signal increase was observed. fMR imaging may detect activity-rel...
متن کاملScalloping deformity of the corpus callosum following ventricular shunting.
PURPOSE To describe six patients who underwent ventriculoperitoneal (V-P) shunting for hydrocephalus and developed scalloping deformity of the dorsal surface of the corpus callosum, and to evaluate the cause and frequency of this phenomenon. MATERIALS AND METHODS MR images of 35 patients whose hydrocephalus was successfully corrected by V-P shunting were studied. To elucidate the possible ana...
