The prognosis of primary pontine hemorrhage depends on the size,location, and extent of the hematoma.We investigated the relationship between CT features and prognosis in 61 consecutive cases.The CT features were classified into four types:basal-tegmental(23 cases),bilateral tegmental (7),massive(14),and small unilateral tegmental(17).Case survival rate was 94.1%for the small unilateral tegmental type,26.1%for the basal-tegmental type,14.3%for the bilateral tegmental type,and 7.1%for the massive type. |
