A head CT was performed which showed an EDH in the right frontotemporal region, measuring up to 7 mm in transverse dimension, with additional thin subdural hemorrhage extending along the lateral margin of the right temporal lobe [Figure 1].
Frontal (left) and lateral (right) microangiography of the right MMA without evidence of pseudoaneurysm or active extravasation.
