Fig 3. An 82-year-old man underwent imaging 0.5 hours following onset of right-sided weakness. Admission NCCT (A) and CTA (B) demonstrate hemorrhage in the left midbrain without active extravasation on CTA. C, Admission CECT, however, reveals focal high attenuation (arrow) in the left tectal plate, consistent with active extravasation. D, Follow-up NCCT 17 hours later shows hematoma expansion into the left thalamus and lateral ventricle with marked hydrocephalus. The patient had a fatal outcome.
