OBJECTIVE AND IMPORTANCE: A rare observation of double saccular aneury
sms of the meningeal artery is presented. CLINICAL PRESENTATION: This
22-year-old man was referred to the Neurosurgical Institute with a sus
picion of an aneurysm of the anterior communicating artery. Bilateral
angiography of the carotid arteries was performed 1 week after the sub
arachnoid hemorrhage, but the aneurysms were not visualized. Routine a
ngiography of both carotid arteries and selective studies of the left
vertebral artery were performed again, and angiography of the right ca
rotid artery revealed an aneurysm. The patient's neurological state at
the time of admission was normal. Fundoscopic examination revealed pa
pilledema and conjunctival injection of the left eye. INTERVENTION: Th
e patient was treated using a right pterional approach. One aneurysm h
ad caused spontaneous subarachnoid hemorrhage. The aneurysms were remo
ved using a direct approach, with histological examination of dura mat
ter fragment containing both aneurysms. The results of the patient's a
-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 men
ingeal artery can be manifested by subarachnoid hemorrhage, and intrad
ural arterial aneurysms are similar to saccular cerebral vessel lesion
s structurally.
