Predicting hematoma growth in spontaneous intracerebral hemorrhage: A simplified non-contrast computed tomography based five-point grading approach

Figure 4 Black hole sign in 68-year-old woman who presented with sudden onset of aphasia and right-sided weakness. A: Axial non-contrast computed tomography (NCCT) image performed 3-hours after hospital admission showed left basal ganglia hematoma with a black hole sign (blue arrow); B: Follow-up NCCT 6-hours later showed a significant hematoma expansion with intra-ventricular extension.
