Mesencephalic hemorrhage (MH) is a rare presentation of spontaneous intraparenchymal hemorrhage. This study aims to evaluate prognostic parameters of the MH outcome. We conducted an extensive search in the literature for cases with spontaneous, isolated mesencephalic hemorrhage. The study was conducted according to the statement of Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Sixty-two eligible cases have been reported in the literature as proven by CT or MRI, and to these, we added six cases confirmed by MRI. The modified Rankin Scale (mRS) was dichotomized into two groups as the favorable outcome (FO; score, 0-2) and unfavorable outcome (UO; score, 3-6). Of the 68 patients studied, 26 (38%) presented with normal consciousness, 22 (32%) with lethargy , and 20 (29%) with stupor or coma. There was no cause of hemorrhage in 26 (65%) patients with FO and 12 (43%) with UO (p=0.059). In univariate analyses, neither arteriovenous malformations (p=0.33) nor cavernomas (p=0.19) were associated with outcome. Multiple logistic regression analysis revealed that hypertension (OR, 51.22; CI95%, 1.92-1370.24; P=0.019), consciousness (OR, 133.54; CI95%, 1.61-1113.3; P=0.03), NIHSS at admission (OR, 57.23; CI95%, 2.87-1141.2; p=0.008), and ventrodorsal hemorrhage size (≥1 cm) (OR, 61.83; CI95%, 2.15-1779.2; p=0.016) were significantly associated with UO. Three months after stroke, 40 patients (59%) had FO, 28 (41%) had UO, and 8 (12%) died. These results suggest that ventrodorsal size of hemorrhage and clinical severity at stroke onset are possible predictors of functional outcome after mesencephalic hemorrhage.
