Choroid plexus papillomas are uncommon neoplasms of the central nervous system, accounting for 0.4% to 0.1% of all intracranial tumors. We present a choroid plexus papilloma in the trigone of the lateral ventricle in an 8 months old infant with hydrocephalus. We successfully controlled hydrocephalus and subdural fluid collection after total removal of the mass.

We have analysed 144 patients with hypertensive putaminal hemorrhage, admitting from January 1992 to December 1993. Surgical treated group with Komai's stereotactic system was 71 patients and medical treated group was 73 patients. The results were as follows: 1) The patients with ventricular rupture were 36 cases(25%). According to the degree of ventricular rupture, the mortality was increased and the good outcome was decreased(P<0.01). 2) The prognosis was evaluated in favorable condition(alert and drowsy) and unfavorable condition(stuporous, semicomatose, comatose). In unfavorable condition, the mortality of surgical patients was lower than that of non-surgical patients(P<0.01). 3) Surgical patients with smaller hematoma(< or = 40ml) showed btter outcome than non-surgical patients:The statistical difference was not significant. But in larger hematoma(>40ml), the outcome in both treated group was similar. 4) According to CT classification, in class II(extending to anterior limb of internal capsule), good outcome of surgical group was better than that of non-surgical group. In class V(extending th thalamus or subthalamus), the mortality in surgical group was lower than that of non-surgical group(P<0.05) .

OBJECT: Object of this study is to study which factors affect the prognosis in spontaneous thalamic hemorrhage treated with conservative method, stereotactic surgery and extraventricular drainage. MATERIAL AND METHODS: We analyzed 127 patients with spontaneous thalamic hemorrhage for evaluating the factors affecting prognosis. Various factors such as age, sex, location of hematoma, Glasgow coma scale(GCS) on admission, intraventricular hemorrhage(IVH), ventricular dilatation, CT classification, hematoma diameter, 4th ventricle dilatation, and treatment modality. RESULTS: The results were as follows: 1) Of the 40 patients with GCS of 3 to 8, 15 patients(37.5%) died. Of the 34 patients with GCS of 13-15, 33 patients(97%) survived 2) The 99 patients had intraventricular hemorrhage and 25 patients(25.2%) died. The 28 patients had no intraventricular hemorrhage and they all survived. 3) Of the 24 patients in whom the cerebrocaudate index(CCI) was more than 0.25, 10 patients(41.6%) died and only 2 patients had good prognosis. The 35 patients had no ventricular dilatation and all 35 patients survived 4) Of the 23 patients extending to hypothalamus or midbrain with ventricular hemorrhage, 11 patients(47.8%) died and 12 patients(52.1%) survived. 5) Of the 10 patients in whom hematoma diameter was more than 45mm, 4 patients(40%) died and 6 patients(60%) had a poor prognosis. 6) The 31 patients had hemorrhagic dilatation of the fourth ventricle and 16 patients(51.6%) died. Of the 29 patients with ventricular hemorrhage and no dilatation, 6 patients(20.6%) died. CONCLUSION: Multiple logistic regression analysis showed prognostic factors: GCS score(p<1/20.0001), extending to hypotahalamus or midbrain with ventricular hemorrhage(p<1/20.0001), thalamic hematoma with IVH(p<1/20.0001), dilated 4th ventricle hemorrhage(p<1/20.0012), hematoma diameter(p<1/20.0001), CCI(p<1/20.0001).
