Duplicated right MCA

Case contributed by Dr Maxime St-Amant


Incidental finding

Patient Data

Age: 65
Gender: Female

CTA demonstrates two parallel arteries arising from the terminal right ICA. The anteriormost artery has a slightly smaller caliber.

DSA (angiography)

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.
