Fig. 1 (a) Sagittal T1- and (b) axial T2-weighted magnetic resonance imaging demonstrating a dorsolateral midbrain cavernous malformation with evidence of recent hemorrhage. Postoperative (c) sagittal T1- and (d) axial T2-weighted magnetic resonance imaging demonstrates complete removal of the lesion.

Fig. 2 Intraoperative photographs demonstrating (a) the lateral mesencephalic safe entry zone located at the intersection of the branches of the superior cerebellar artery and fourth nerve with the vein of the lateral mesencephalic sulcus, (b) mobilization of the cavernous malformation, and (c) its removal from the brainstem.
