Figure 4. Hypertensive intraparenchymal hematoma with subfalcine herniation. Nonenhanced axial computed tomography demonstrates a large right basal ganglionic hypertensive bleed (*) with mass effect and midline shift or a subfalcine herniation to the left (arrows). The frontal horns are part of the lateral ventricles. The right frontal horn is compressed so severely that it is almost completely obliterated. Dilation of the left frontal horn is due to obstructive hydrocephalus – a consequence of compression of the third ventricle.
