Background: Intraorbital aneurysms are rare, and most of them originate from the ophthalmic arteries. Herein, we report a case of meningolacrimal artery aneurysm associated with a meningioma.
Case Description: A 55-year-old woman had a frontal convexity meningioma identified by brain magnetic resonance imaging during a checkup. Cerebral angiography revealed the middle meningeal artery as a feeding artery as well as the presence of an aneurysm associated with the meningolacrimal artery. Embolization of the feeding artery was performed before the removal of the meningioma. The meningioma was resected, and the aneurysm was removed with a bone flap. The patient was discharged without any complications.
Conclusion: We report a meningolacrimal artery aneurysm associated with a meningioma. Embolizing the feeding artery of the aneurysm was helpful in safely resecting the meningioma.

Intraorbital aneurysms are a rare occurrence, and most of them originate from the ophthalmic artery. A standard treatment for these aneurysms is yet to be established. We report a case of a meningolacrimal artery aneurysm of the feeding artery associated with a frontal convexity meningioma. The patient has provided informed consent to publish this report.
Case presentation and imaging
A 55-year-old woman was incidentally found to have a brain tumor on brain magnetic resonance imaging (MRI) at a checkup. The tumor was considered to be a frontal convexity meningioma based on contrast-enhanced brain MRI, and tumor resection was planned after informed consent was obtained [
(a and b): T1-weighted axial (a) and sagittal (b) contrast-enhanced magnetic resonance imaging (MRI) showing a meningioma in the right convexity region, (c) T1-weighted axial contrast-enhanced MRI showing the aneurysm in the orbital cavity (white arrow), (d and e) frontal (d) and side (e) views by angiography of the right external carotid showing that the meningioma had blood flow mainly from the middle meningeal artery and the presence of a right intraorbital aneurysm, (f) axial imaging of enhanced cone-beam computed tomography showing that the aneurysm is associated with the meningolacrimal artery through the cranio-orbital foramen (white arrow head) and is present in the orbit cavity (white arrow).
Embolization of the feeding artery was performed before resecting the meningioma to reduce intraoperative bleeding. We normally use N-butyl-2-cyanoacrylate (NBCA) for embolization of a feeding artery. Therefore, to prevent the migration of NBCA into the ophthalmic artery, we decided to occlude the meningolacrimal artery proximal to the aneurysm before injection of NBCA. The procedure was performed under local anesthesia. A 5-Fr long sheath was placed into the right femoral artery. A 5-Fr guiding catheter (ENVOY; Johnson and Johnson, New Brunswick, NJ) was placed into the right external carotid artery, and a microcatheter (Marathon; Medtronic, Dublin, Ireland) was placed into the meningolacrimal artery using a microguidewire (CHIKAI10; Asahi Intecc, Aichi, Japan). Then, five detachable coils (ED coil; Kaneka Corporation, Tokyo, Japan) were inserted into the meningolacrimal artery [

Resection of the meningioma
We performed an orbitofrontal craniotomy for resection of the meningioma [

Intraorbital aneurysms are rare – there are only 22 reported cases to the best of our knowledge,[
The natural history of intraorbital aneurysms is unclear. There are few reports of spontaneous rupture, only two cases are reported.[
The prevalence of the cooccurrence of a brain tumor and an aneurysm is about 0.3–1%.[
We report a case of a meningolacrimal artery aneurysm associated with a frontal convexity meningioma. The artery was occluded before tumor resection, and the aneurysm was removed through craniotomy. Embolizing the feeding artery with the aneurysm was helpful in safely resecting the meningioma.
