Presentation
Incidental finding.
Patient Data
Age: 65 years
Gender: Female
From the case:
Duplicated middle cerebral artery
{"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/66674/annotated_viewer_json?lang=us"}
CTA demonstrates two parallel arteries arising from the terminal right ICA. The anteriormost artery has a slightly smaller caliber.
From the case:
Duplicated middle cerebral artery
{"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/66675/annotated_viewer_json?lang=us"}
DSA again demonstrates two parallel arteries originating from the terminal right ICA.
Case Discussion
The findings are in keeping with a duplicated right MCA rather than an accessory right MCA since the artery originates directly from the ICA and not from the ACA.
