Imaging of inner cerebral trauma.

Abstract

The concept of "Inner cerebral trauma" (ICT) has been preliminary defined as a characteristic topographic pattern of deep brain lesions produced by physical forces occurring within the cranial cavity in closed head injury of the acceleration/deceleration type. The lesions, based on neuropathological examinations, are characteristically localized in the "centro-axial" regions of the brain. The extent of ICT is often underestimated by CT. Due to assess the value of MR imaging, 83 patients with ICT were examined on a 1.5 T unit in different stages after trauma. The pattern of lesions, as shown with MR imaging, correlated well with neuropathological studies, suggesting a multifocal pathogenesis of severe traumatic brain injury.
