뇌종양에 의한 두개강내 출혈 = Spontaneous Intracranial Hemorrhage Caused by Brain Tumor

다국어 초록 (Multilingual Abstract)

919 consecutive brain tumor cases and 665 consecutive spontaneous intracranial hemorrhage cases were reviewed for the analysis of cases in which spontaneous intracranial hemorrhage caused by brain tumor was confirmed with gross operative findings.
Authors analyzed their incidence, patients' demography, tumor histology, clinical symptoms and signs, predisposing factor, tumor vascularity, type of hemorrhage, relations between the clinical symptoms and signs and the type of hemorrhage, relations between the location of tumor and the type of hemorrhage and the outcome of treatment.
The conclusions are as follow ;
1) The proportion of the hemorrhage caused by brain tumor to the total spontaneous intracranial hemorrhage was 5.1％(34/665).
2) The proportion of the spontaneous intracranial hemorrhage caused by brain tumor to the total brain tumor was 3.7％(34/919) and the proportion of that excluding pituitary adenoma was 2.5％ (18/729).
3) Compared with the other brain tumors, oligodendroglioma and pituitary adenoma had significant tendency of hemorrhage (p＜0.05, p＜0.01, respectively) and meningioma had a significantly low incidence of hemorrhage(p＜0.05).
4) The hemorrhage brought about major symptoms in 13 cases(72％), minor symptoms in 2 cases (11％). Three cases showed no symptoms related to the hemorrhage.
5) Among the 18 cases of spontaneous intracranial hemorrhage caused by brain tumor, one case with the major attack died of postoperative pneumonia. There were additional 2 motalities which were not related to the preoperative hemorrhage. And most of the symptoms associated with the preoperative hemorrhage stabilized or improved with operative treatment.
