Presentation
Right upper limb weakness and aphasia.
Patient Data
Age: 65 years
From the case:
Left MCA infarct with recanalization
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/51615/annotated_viewer_json?lang=us"}
Old left MCA infarct. Mismatch MCA left. M2 occlusion more easily apparent as "dot" in Sylvian fissure.
Bone subtraction MIP CTA shows arch to the vertex. If bone subtraction and only axials available can be difficult to identify M2 or M3 occlusions. CTP can point the way. Most of CBF core is old infarct.

Reperfused. Small volume scattered infarct.
Case Discussion
Thin CT & CTP helps with cta assessment. M2 higher rate of recanalization c.f. MCA and ICA
