An MRI/MRA head to pelvis was performed which demonstrated dolichoectasia of the internal carotid and left vertebral arteries, tortuosity of vessels within the chest, particularly vessels arising from the aortic arch, high-grade stenosis at the origins of the right common carotid and right subclavian arteries and proximal left common carotid artery, marked pectus deformity (Haller index of 13.4) causing compression of the right atrium and leftward shift of heart, and lastly a mildly tortuous left renal artery.
A hormonal influence on the incidence of aneurysm formation is supported by the fact that the greatest incidence of adenoma-associated aneurysms occurs in the context of acromegaly (50%) (1), with associated increased insulin-like growth factor--1 potentially playing a role in the formation of intracranial aneurysms, as well as the more diffuse vasculopathic changes that can be seen in these patients, to include widespread cerebrovascular dolichoectasia (2).
