    Abstract:
    A case is reported of mycotic aneurysm at the petrous portion of the internal carotid artery (ICA) treated with an endovascular procedure. A sixty-seven-year-old male who had suffered from chronic otitis media bilaterally for the last five years showed a sudden onset of massive left otorrhagia. Cerebral angiogram at the eighth day of otorrhagia disclosed a big aneurysm at the petrous portion of the left ICA. The aneurysm was round in shape but its wall was irregular. The angiogram also showed that a stenotic finding of the left ICA just at the proximal portion of the aneurysm and the neck of the aneurysm was not broad. Bone window computed tomography showed a destroyed petrous bone around the left ICA. The results of the Matas test and the Allcock test told us that left ICA occlusion should not be selected as a treatment. We decided that endovascular surgery could be applied as the treatment of this pathology. An endovascular procedure was performed for this pathology one month after the otorrhagia. The aneurysm was successfully embolized using platinum coils beside a part of the neck without occlusion of the parent artery. The patient's postoperative course was not eventful. We concluded that endovascular surgery might be the first choice for the treatment of an ICA petrous portion mycotic aneurysm.
