A higher blood burden and the presence of intraparenchymal extension of the bleeding (intracerebral hemorrhage [ICH]) are well known predictors of poor outcome. Only few studies have addressed the role of hematoma location on patient's functional outcome. The main aims were to compare clinical and radiographic characteristics between SAH patients with and without ICH and to compare different ICH localizations in relation to long\u2010term functional outcome.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We prospectively collected data on 280 consecutive SAH patients (aneurysmal and non\u2010aneurysmal) admitted to a tertiary care hospital between 2010 and 2017 and assessed the initial computed tomography scans of the brain acquired after intensive care unit admission. Poor functional outcome was defined as a modified Rankin Scale score\u2009&gt;2, 3\u2009months after SAH. We used multivariable logistic linear regression to investigate associations between ICH location and clinical variables as well as functional outcome.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Intraparenchymal extension of the hemorrhage was observed in 59\/280 patients (21%). The median (interquartile range) ICH volume was 11.3 (4.9\u201316.2) ml and the location was supratentorial in 55\/59 patients (93%). Most parenchymal hemorrhages were located in the frontal (<jats:italic>n<\/jats:italic>\u00a0=\u00a024.41%) and temporal lobes (<jats:italic>n<\/jats:italic>\u00a0=\u00a012.21%), followed by insular ICH (<jats:italic>n<\/jats:italic>\u00a0=\u00a07.12%), corpus callosum (<jats:italic>n<\/jats:italic>\u00a0=\u00a06.10%), parietal (<jats:italic>n<\/jats:italic>\u00a0=\u00a02.3%) and occipital locations (<jats:italic>n<\/jats:italic>\u00a0=\u00a02.3%). Among SAH patients with ICH, those with lesions located in the corpus callosum (<jats:italic>n<\/jats:italic>\u00a0=\u00a06\/59) had a significantly higher risk of 3\u2010month poor functional outcome in comparison to all other ICH locations, even after adjusting for Hunt and Hess grade and age (adjusted odds ratio [adjOR] 50.5, 95% confidence interval [CI] 1.3\u20132004.2, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.034).
