Traumatic lesions of corpus callosum: early multidetector CT findings.
Corpus callosum is one of the common sites of brain lesion, whose involvement is an indicator of a more severe prognosis, produced by traumatic shearing stresses resulting in diffuse axonal injury (DAI). Computed tomography (CT) in acute phase is considered to have a limited role for the detection of non-hemorrhagic or petechial hemorrhagic DAI lesions. New generation multidetector CT scanners allow faster acquisition of thinner-slice images and post-processing reformations. Three patients with severe closed head trauma underwent CT examinations using a multidetector scanner, a few hours and the day after injury. The review of original images with narrow window width and integration with reconstruction of thinner slices from raw-data and post-processing multiplanar reformations (MPR) helped to detect the onset of hypodense or predominantly hypodense areas of corpus callosum, not present at admission and afterwards confirmed by MRI.
