Successful endovascular treatment of a ruptured mycotic intracavernous carotid artery aneurysm in an AIDS patient.
BACKGROUND
As the medical treatment for human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) continues to advance, the HIV-related aneurysms may pose a clinical problem of increasing magnitude. The authors report on a successfully treated ruptured mycotic intracavernous carotid artery aneurysm case in an AIDS patient.


METHODS
This 41-year-old AIDS patient presented with severe epistaxis. His head CT revealed acute blood in the left sphenoid sinus with bony erosion of the lateral wall (Fig. 1). The cerebral angiogram demonstrated a quite irregularly shaped intracavernous carotid artery aneurysm with proximal arterial stenosis (Fig. 2).


RESULTS
After balloon test occlusion, this aneurysm was trapped endovascularly with detachable balloons (Fig. 3). The blood culture was positive for Aspergillus. The patient died 2 years later from other AIDS-related causes.


CONCLUSIONS
The cerebral aneurysms in HIV/AIDS patients can be generally categorized into two groups: the mycotic aneurysms from bacterial or fungal infections and the HIV-associated aneurysms as a distinct entity. To plan appropriate interventions, a high degree of clinical suspicion must be exercised to promptly recognize the mycotic nature of many HIV-related aneurysms.
