What is a Cerebral Contusion? - Oren Zarif - Contusion Cerebral

A cerebral contusion is a bruised area of brain tissue. It most commonly occurs in the frontal lobes and undersurface of the brain. The brain can bruise on its own or be injured when it strikes a ridge or fold in the dura mater. While this type of brain injury can cause significant pain, it may also result in other types of bleeding. If the injury is severe enough, cerebral edema develops around the area. A computed tomography (CT) brain scan is the best way to diagnose a contusion.

The volume of the contusion was calculated from cranial CT data taken within 24 h of admission. The volume of the contusion was calculated by manually selecting voxels adjacent to the area of interest and setting thresholds based on Hounsfield units. Specifically, thresholds of 50 to 110Hu were used to separate the contusion from the surrounding environment. A CT data set of patients who were admitted on the third day of the contusion was chosen for the measurement.

The location of focal perfusion deficits varied in patients. In twenty-five percent of cases, the region of trauma was the most affected. Twenty-one patients had focal perfusion deficits whereas seven percent had multifocal deficits. The location of the concussion largely determined the extent of the perfusion deficit. In two patients, the frontal lobes were affected by diffuse hypoperfusion. The time from the trauma to the time of brain SPECT scan was positively related to the number of focal perfusion deficits.
