Relationship between the clinical manifestations, computed tomographic findings and the outcome in 80 patients with primary pontine hemorrhage.

The relationship between the clinical manifestations, computed tomographic (CT) findings and the outcome in 80 patients with primary pontine hemorrhage (PPH) was analyzed to clarify factors predicting the outcome. Patients were 58 males and 22 females (60. 5+/-12.9 years old) with PPH. Correlations between the clinical manifestations, CT findings and the outcome was assessed with multivariate regression analysis. The initial level of consciousness and the transaxial size of the hematoma on CT were strongly related to the outcome. In patients with small hematoma (with the transaxial size </=20 mm), pupillary abnormalities of onset and acute hydrocephalus were related to the outcome of PPH.
