The preoperative MRI showed a hypervascular left sphenoid wing meningioma, which enhanced heterogeneously and embedded the intracranial portion of the left internal carotid artery and proximal segment of the middle cerebral artery (Fig. 1A, B and C). On DSA, the branches of ICA and ECA on the same side fed the meningioma (Fig. 1D and E).
(A), (B) and (C). Post-operative left sphenoid meningioma enhanced and embedded ICA and MCA (black arrow). D and E, STA-MCA bypass had a good flow (white arrow).
