Abstract
Objective: Infection associated with coil embolization of cerebral aneurysm is very rare. We describe a case of brain abscess formation following coil embolization of a cavernous carotid artery giant aneurysm.
Case presentation: This 59-year-old man complained of double vision due to a left cavernous carotid artery giant aneurysm. Embolization of the aneurysm using platinum coils was performed. However, the patient presented double vision again 1 year later. MRI showed brain abscess in the left temporal lobe, which appeared continuous with the aneurysm. His neurological condition rapidly deteriorated despite administration of antibiotic drugs. After additional aneurysm embolization and parent artery occlusion, brain abscess was surgically treated. Under the microsurgical view, the brain abscess directly connected the aneurysm and platinum coils were detected through a perforated wall of the aneurysm. Without removal of the coil, infection was completely resolved.
Conclusion: Coil infection of cerebral aneurysm should be noted, however it is very rare.
