Differential spinal cord blood flow was measured in dogs by the radioactive microsphere injection method. The mean spinal cord blood flow was 10.8 +/- 0.53 (SE) ml/100 g/minute. The flow values for the white and gray matter were 7.1 +/- 0.65 (SE) and 26.3 +/- 2.2 (SE) ml/100 g/minute, respectively.
The authors documented by computerized axial tomography a case of massive brain swelling occurring within 20 minutes of a closed head injury. It is suggested that the cause of the brain swelling is acute vascular dilatation.
A patient with clinical and radiographic findings initially suggesting a neoplasm was diagnosed as having Hodgkin disease.
