ABSTRACT
OBJECT: Spontaneous pontine hemorrhage can be diagnosed by CT or MRI, but the clinical course is variable according to the location of the hemorrhage. MATERIALS AND METHODS: Author attempted to analyse 39 cases of spontaneous pontine hemorrhage, considering factors to influence their prognosis, admitted in Inje University Busan Paik Hospital from 1998 to 2002. RESULT: Pontine hemorrhage was classified according to the finding of CT scan;4 cases of Type I (hematoma, localized in the tegmentum), 18 cases of Type II (those in the tegmentolaterally), 16 in Type III (those in the basis pontis mainly with tegmentum and midbrain). Male to female ratio was 31:8, mean age was 48.2 years (9-76 years). Initial Glascow Coma scale was 7.6 (3-14), and mean follow-up period was 5.1 months (0.1-52 months). Associated diseases were as follows;hypertension;20, pulmonary tuberculosis;2, hypertension with D.M;1. Treatment modality was consisted of 36 conservative treatment, 1 stereotactic hematoma aspiration, 2 Gamma-Knife radiosurgery for associated cavernous malformations. Prognosis was good at following order of the tegmentotectal, tegmentolateral type. CONCLUSION: The prognosis of tegmentotectal, tegmentolateral type hemorrhage was better than basis pontis. The little volume of the hematoma, the better prognosis.
