FIG 2. A, Source axial CTA image at the level of the bodies of the lateral ventricles showed a layering fluid collection in the ventral aspect of the hematoma including a dependent hyperattenuated component dorsally (long arrow) and a nondependent hypoattenuated component ventrally (short arrow). The hyperattenuated component represented contrast whereas the non-dependent component likely represents plasma.

B, Sagittal multiplanar reformatted image of the CTA source data set showed multiple areas of "nonanatomic puddling" of contrast (circles) within the hematoma indicating active extravastion during the CTA examination.
