RIGHT FRONTAL PETECHIAL HEMORRHAGIC CONTUSION Contusions may be hemorrhagic or nonhemorrhagic. They are part of the spectrum of cranio-cerebral trauma. Although there is no obvious mass effect, and there may not be neurologic deficits solely due to the presence of this particular lesion, there are usually areas of associated brain injury known as diffuse axonal injury (DAI) which may account for more severe neurologic deficits. An MRI will demonstrate more subtle anomalies which cannot be demonstrated on CT scan examination. RIGHT FRONTAL HEMORRHAGIC CONTUSION. The arrowhead points to a punctate area of intraparenchymal hemorrhage which does not demonstrate significant mass effect. Please note the symmetry of the frontal horns of the lateral ventricles as well as the midline position of the third ventricle. The Sylvian fissures are also well characterized bilaterally.
