Objective And Importance:
A rare observation of double saccular aneurysms of the meningeal artery is presented.
Clinical Presentation:
This 22-year-old man was referred to the Neurosurgical Institute with a suspicion of an aneurysm of the anterior communicating artery. Bilateral angiography of the carotid arteries was performed 1 week after the subarachnoid hemorrhage, but the aneurysms were not visualized. Routine angiography of both carotid arteries and selective studies of the left vertebral artery were performed again, and angiography of the right carotid artery revealed an aneurysm. The patient's neurological state at the time of admission was normal. Fundoscopic examination revealed papilledema and conjunctival injection of the left eye.
Intervention:
The patient was treated using a right pterional approach. One aneurysm had caused spontaneous subarachnoid hemorrhage. The aneurysms were removed using a direct approach, with histological examination of dura matter fragment containing both aneurysms. The results of the patient's 2-week follow-up examination were normal. Follow-up angiography of the right carotid artery showed absence of the aneurysm with a clip on the branch of meningeal artery.
Conclusion:
Saccular aneurysms of the meningeal artery can be manifested by subarachnoid hemorrhage, and intradural arterial aneurysms are similar to saccular cerebral vessel lesions structurally.
