This study was conducted to determine whether spot sign score correlates with average rate of hematoma expansion and whether average rate of expansion predicts in-hospital mortality and clinical outcome in spontaneous intracerebral hemorrhage (ICH). The study included 367 patients presenting to the Emergency Department (ED) from January 1, 2000 to December 31, 2008 with nontraumatic ICH. All received noncontrast computed tomography (NCCT) of the head and multidetector CT angiography (MDCTA) on presentation to the ED and a follow-up NCCT within 48 h. Imaging was used to determine the hematoma location and volume, average rate of expansion, and spot sign score. Primary outcome measures included in-hospital mortality and clinical outcome based on modified Rankin Scale at 3 months or at discharge. Regression analysis was performed to correlate spot sign score and average rate of hematoma expansion. ICH expansion was identified in 194 of 367 patients (53%). In a multivariate analysis, rate of ICH expansion predicted mortality (hazard ratio 1.1, CI 1.08-1.12, p?
