We report a patient with an infratentorial lesion resected under a far-lateral approach during awake craniotomy to optimize intraoperative monitoring. A 72-year-old man presented with falls, difficulty walking, and lower extremity weakness. MRI revealed a 2.2 by 2.3 by 2.8 cm mass at the right cervicomedullary junction, with mass effect on the adjacent spinal cord. During two attempts during surgical positioning under general anesthesia, motor evoked potentials were lost. Each time the… CONTINUE READING
