Resumen

VALLEJO, Santiago et al. Imaging changes in the corpus callosum after ventricular shunting: Case reports and literature review. Rev. argent. radiol. [online]. 2012, vol.76, n.3, pp.211-215. ISSN 1852-9992.

We report the cases of two patients with ventricular drainage due to idiopathic hydrocephalus and fourth ventricle cysticercosis, respectively. A follow-up MRI demonstrated increased volume of the corpus callosum with areas of prolonged relaxation without restriction on water diffusion sequences. Pathophysiologic theories include direct mechanical effects after the catheter insertion, chronic compression of the corpus callosum against the falx due to hydrocephalus, ischemia due to elongation of perforating pericallosal arteries not detected before shunting due to thinning of the corpus callosum, and decompressive changes leading to corpus callosum expansion and interstitial edema. These findings might be related to the history of ventricular shunt and hydrocephalus with no apparent clinical significance.
