RT Journal Article SR Electronic T1 Bilateral Internal Carotid Aneurysms Presenting as a Nonpulsatile Parapharyngeal Mass: Complementary Diagnosis by CT, MR Imaging, and Digital Subtraction Angiography JF American Journal of Neuroradiology JO Am.

FD American Society of Neuroradiology SP 864 OP 866 VO 22 IS 5 A1 Muñoz, Alberto A1 Campollo, Jorge A1 Vergas, Joaqín YR 2001 UL http://www.ajnr.org/content/22/5/864.abstract AB Summary: We report fusiform aneurysms in both internal carotid arteries in a 74-year-old man who presented with a nonpulsatile retropharyngeal mass. Both helical CT and MR imaging disclosed the nature of the lesions. Arteriography, required for therapeutic decisions, confirmed the diagnosis. Because of the rarity of this condition and the potential for misdiagnosis, we describe the findings on complementary radiologic examinations.
