J. Neuroradiol.1980 Sep 01; 1 AB - Ten computed tomography (CT) brain scans were evaluated in nine patients with acute carbon monoxide poisoning. The most common CT feature was symmetrical bilateral basal ganglia abnormalities. The lesions appeared as symmetrical low density areas, more dense than cerebrospinal fluid in the early stage and as well defined and more lucent lacunae in the late stage. A second feature was symmetrical and diffuse white matter low density areas. The low density areas, attributed to edema, were poorly defined and faintly lucent in the early stage. They became better defined and more lucent later as permanent necrotic changes developed. Ventricular dilatation and sulcal widening developed as late changes.
