Figure 1.

Non-contrast head CT (Fig 1A) demonstrates frontal lobe hemorrhage (arrows). Source image from MRA of the brain (Fig 1B) demonstrates 8 mm aneurysm in the distal A1 segment of the right ACA (arrowheads). DSA (AP/oblique) from right ICA injections (Fig 1C) confirms aneurysm of the distal A1 ACA segment. 3-D TOF MRA abdomen (Fig 1D) with bilateral internal iliac artery aneurysms (arrows), narrowing of mid-abdominal aorta (arrowheads), diffusely narrowed bilateral common and external iliac arteries (asterisks). 2-D TOF MRA abdomen (Fig 1E) shows worsening involvement of left common iliac artery (arrows), with right external and internal iliac arterial aneurysms unchanged (arrowheads).
