Case Discussion
There is a known association of pericallosal lipoma with azygos ACA 1,2. Both intracranial arteries and intracranial lipomas develop quite early during gestation, which could explain their association, with both the ACA and the pericallosal lipoma being midline structures.
Unsurprisingly, all findings in this MRI study were unchanged compared to previous studies done 3 and 5 years prior.
