- Fig 1.
Coronal (A) and sagittal (B) T1-weighted postgadolinium MR imaging showing a large meningioma, on the left great sphenoid wing, with intense and homogeneous contrast enhancement. DSA of the left ICA, in anteroposterior (C) and lateral views (D), showing intense tumoral blush, fed mainly by recurrent meningeal artery branches of the OPH. E, Roadmap of left internal carotid artery showing the microcatheter positioned in recurrent meningeal artery. Arrow shows the probable OPH segment from where the central retinal artery arises. Arrowheads and curved line delimitate the location of the choroidal crescent. F, Anteroposterior view X-ray showing the final cast of Onyx; DSA of left internal carotid artery (G) and lateral (H) views, with preservation of the choroidal crescent (arrowheads).
- Fig 2.
Digital subtracted fluoroscopy in anteroposterior view (A) and lateral view (B) demonstrating the filling of the major afferent arteries of the meningioma. Digital subtracted fluoroscopy in anteroposterior view (C) and lateral view (D), demonstrating the deep penetration into small-to-medium tumor vessels.
