title: [Mycotic aneurysm of the internal carotid artery].
abstract: The detection of aneurysms of the internal carotid artery due to acute or chronic neck infections seems to be a rather rarely event. However, if aneurysms or pseudoaneurysms of the neck region occur, than mostly by bleeding complication or unclear significant soft tissue swelling. The case of a patient is reported, who underwent an abscess tonsillectomy. The intraoperative situation of the right tonsillar fossa was found to show suspicious pulsations under the scarred and inflamed peritonsillar tissue layer. The postoperative performed intraarterial angiography verified the diagnosis of the aneurysm of the internal carotid artery nearby the tonsillar fossa. The diagnosis mycotic aneurysm has been concluded by the long lasting tonsillitis history with one further peritonillar abscess in the past, intraoperative and histological signs of peritonsillitis and the the result of an intraarterial angiography carried through 10 years ago without any clue to aneurysm. A bleeding complication did not occur in this case. The patient went into the care of vascular surgeons with the indication to perform a stent application.
