BACKGROUND: Ruptured intracranial fungal mycotic aneurysms have a high mortality rate. It has been reported that the number of opportunistic infections has increased. Here, we report the first case of a patient in which a ruptured fungal carotid artery aneurysm was successfully treated by stent-assisted coil embolization.
CASE DESCRIPTION: A 76-year-old male receiving dual antiplatelet therapy due to a recent percutaneous transluminal angioplasty presented with blurred vision of the right eye and diplopia. Magnetic resonance imaging revealed a fungal mass in the sphenoid sinus, and the patient was pathologically diagnosed with invasive aspergillosis. After receiving oral voriconazole for 4 weeks, he was admitted to the hospital with hemorrhagic shock from epistaxis. The right internal carotid artery angiography revealed a de novo irregularly shaped aneurysm at the cavernous portion, projecting into the sphenoid sinus, which was considered to be the source of bleeding. Due to the lack of ischemic tolerance and urgent demand for hemostasis, we performed a stent-assisted coil embolization of the aneurysm without interrupting the blood flow. Postoperatively, the patient had no neurological deficit, and treatment with voriconazole was continued for 12 months without rebleeding.
CONCLUSION: Stent-assisted coil embolization without parent artery occlusion might be a promising option for the urgent treatment of ruptured fungal mycotic aneurysms. Long-term administration of voriconazole might be continued for 12 months for such patients.
