R ACA

Points:

Presence of acute infarction: Yes

Location: right frontal lobe, medial frontal gyrus

Territory: right ACA

Etiology: Ischemic

Mass effect: None

Example report text:

There is a small region of hypoattenuation in the medial frontal gyrus of the right frontal lobe consistent with acute right ACA territory infarction. There is no significant mass effect or hemorrhagic transformation.

Discussion:

This is a small infarct that would be easy to miss if you were not specifically looking for it. Using a more narrow stroke window (also known as a 40/40 window, because the window level an window width are both set to 40) can help accentuate the hypoattenuation in this region and improve detection.
