Ferroli and colleagues note that anterior gyrus cinguli tumors may be approached contralaterally. In our series of anterior gyrus cinguli tumors, we used-among others-the interhemispheric bilateral approach in perigenual tumors extending contralaterally and the unilateral approach in perirolandic tumors, based on the finding that tumors never extend contralaterally at this level. From this observation and evidence for the absence of drawbacks to the ipsilateral interhemispheric approach in small lesions, we believe that the contralateral approach may not necessarily offer an additional advantage over the ipsilateral approach. Furthermore, maneuvers like falx transection with division of the inferior sagittal sinus and the falcine venous plexus, which can carry unpredictable consequences for venous drainage, are not justified in our opinion.¹ However, we were aware of this approach and mentioned it in the discussion, but, because of its limited indications and the scarce success...
