The radiographic and pathologic features of 13 cases of mycotic aneurysm of the aorta were reviewed retrospectively. In four cases the mycotic aneurysm was associated with bacterial endocarditis following aortic valve replacement, and in nine cases it was associated with spontaneous bacterial endocarditis. Postmortem examination revealed that the mycotic aneurysm was most frequently found in cases with bicuspid aortic valves. In all cases the chest radiograph revealed cardiomegally, usually with pulmonary vascular congestion. In the six patients in whom the diagnosis was established angiographically, the aneurysm was manifested by an irregular saccular collection of contrast medium under one of the coronary arteries. Mycotic aneurysms must be differentiated from other lesions with similar angiographic findings, such as a congenital aneurysm of the sinus of Valsalva, prolapse of an aortic cusp through a membranous ventricular septal defect, and a congenital aortic-left ventricular tunnel.

A 74-year-old man with diabetes mellitus type II, retinopathy and polyneuropathy suffered from exophthalmus, ptosis and diplopia. Magnetic resonance imaging and computer tomography showed a space-occupying process in the right orbital apex. An extranasal ethmoidectomy accompanied by an orbitotomia revealed the presence of septated hyphae. Aspergillus fumigatus was grown from the tissue. After surgical removal of the fungal masses, therapy with amphotericin B (1 mg kg(-1) body weight) plus itraconazole (Sempera, 200 mg per day) over 6 weeks was initiated. Five months later the patient's condition deteriorated again, with vomiting, nausea and pain behind the right eye plus increasing exophthalmus. Antifungal therapy was started again with amphotericin B and 5-fluorocytosine. Neutropenia did not occur. The patient became somnolent and deteriorated, a meningitis was suggested. Aspergillus antigen (titre 1:2, Pastorex) was detected in liquor. Anti-Aspergillus antibodies were not detectable. Both the right eye and retrobulbar fungal masses were eradicated by means of an exenteratio bulbi et orbitae. However, renal insufficiency and an apallic syndrome developed and the patient died. At autopsy, a mycotic aneurysm of the arteria carotis interna dextra was detected. The mycotic vasculitis of this aneurysm had caused a rupture of the blood vessel followed by a massive subarachnoidal haemorrhage. In addition, severe mycotic sphenoidal sinusitis and aspergillosis of the right orbit were seen, which had led to a bifrontal meningitis.

A 79-year-old woman, with no immune deficit, had presented progressive visual disturbance, diplopia and ptosis of her left eye over 2 weeks. T1-weighted MR images with gadolinium showed a heterogeneously enhanced lesion extending from the left orbital apex along the optic nerve to the cavernous sinus. Although we could not detect fungus by a transsphenoidal biopsy, we suspected fungal infection because of high level of galactomanan antigen in serum. Despite antifungal chemotherapy, her symptoms did not improve. CT image on day 40 showed an aneurysm in the left internal carotid artery, on day 43 cerebral infarction in the left internal carotid artery distribution and on day 45 she died. Autopsy disclosed that aspergillus hyphae invaded the left sphenoid sinus, cavernous sinus and wall of the aneurysm. In this case, fungal infection in the frontal skull base including orbital apex caused mycotic aneurysm in the intracavernous portion of the left internal carotid artery. Skull base aspergillosis presenting orbital apex syndrome is itself rare and in addition, the occurrence of cerebral infarction in the mycotic aneurysm has hardly been reported. We should have cerebrovascular disease in mind as a complication of CNS aspergillosis.

Intracavernous carotid artery mycotic aneurysms are rare and management is determined by clinical presentation. We describe the first documented proximal intracranial mycotic aneurysm treated by a balloon expandable Aneugraft PCS covered stent. An 11-year-old female child presented with acute onset fever, headache, chemosis followed by diplopia, right-sided ptosis with ophthalmoplegia. Magnetic resonance imaging revealed bilateral cavernous sinus thrombosis. Subsequent work-up included serial computed tomographic arteriography and digital subtraction angiography which revealed a progressively enlarging intracavernous carotid aneurysm. An Aneugraft PCS covered stent was successfully deployed endovascularly, and complete exclusion of the aneurysm was achieved while maintaining the patency of the parent artery. The use of covered stents in intracranial vasculature can be an effective and safe treatment modality for exclusion of the mycotic aneurysm in selected cases.

This is the first reported case in which a mycotic aneurysm refractory to the first medical treatment was treated with a Pipeline embolization device (PED), and the first case of a mycotic aneurysm from Brucella treated by endovascular therapy. A 35-year-old man presented with left eye pain and ptosis, and fever for 2 weeks. Before symptom onset, he visited Vietnam where he developed a flu-like illness; however, antibiotics were ineffective. We suspected Brucella as the most likely infectious etiology for the patient's intracavernous aneurysm. Since the aneurysm did not reduce in size following 2 weeks of antibiotic therapy, we placed a PED in the left internal carotid artery. Follow-up angiogram 4 months later showed no residual aneurysm, and cranial nerve palsies had completely resolved. From the results of this case, it appears that flow diverter stenting may be a safe and effective treatment of mycotic aneurysms of the cavernous segment of ICA.
