Sample isolated tentorial SDH. A 78-year-old man who presented after a fall. Baseline axial (A) and coronal (B) images from a noncontrast head CT reveal a small, 3-mm-thick acute subdural hematoma along the right tentorium (arrows) without associated mass effect. Axial (C) and coronal (D) images from a noncontrast follow-up CT performed 6 hours later reveal no new hemorrhage or interval change in size of the initial tentorial SDH (arrows).

Sample isolated falcine SDH. A 65-year-old man with headache after a fall. Axial image (A) from an initial noncontrast head CT shows a lobulated and relatively focal acute high-density SDH along the left side of the anterior falx (arrow). On follow-up CT (B), there has been some mild local redistribution of acute SDH without significant interval change in the overall size or maximal thickness of the hematoma (arrow).
