Fig. 3.

(A) Preoperative volume is associated with surgical outcome, as partial resection is more likely to be obtained in larger tumors, whereas total and subtotal resection is more likely to be obtained in smaller tumors (volume, <100 cm³). A detail of the graph is showed in (B): damaged fascicles are more likely to be found in larger tumors, whereas intact fascicles are more likely to be found in smaller tumors, and the size of 100 cm³ appears as a possible threshold.
