Mycotic aneurysms of the carotid arteries are rare. We describe a right carotid artery mycotic aneurysm in a 70-year-old man. His symptoms began immediately after a complicated molar extraction and persisted until the diagnosis was made and surgical resection and repair were undertaken. Pseudomonas aeruginosa was isolated from multiple blood cultures and excised tissues. We review another 73 cases uncovered by an extensive literature search. Bacteremia, recent surgery, head and neck infections, dental infections, and endocarditis are the most common predisposing conditions. Computed tomography and magnetic resonance imaging are techniques for accurately confirming the suspicion of any aneurysm, but angiography is the gold standard. Primary resection of the aneurysm with native vein interposition, in conjunction with prolonged antibiotic therapy, is the preferred strategy. A total of 6 cases thus far, including ours, have been clearly associated with dental surgical procedures. These cases are characterized by rapidly enlarging neck masses in the presence of fever. Microorganisms, particularly gram-negative rods, in contrast to normal oral flora, eg, streptococci and anaerobes, are often isolated. With prompt diagnosis and treatment, outcome is often satisfactory.
