Seizure-associated venous air embolism during awake craniotomy in the supine position: A case report

Figure 1 Intraoperative photograph during awake craniotomy demonstrating real-time fine motor assessment using a mini piano for continuous evaluation of motor function.

Figure 2 Magnetic resonance imaging. A: Preoperative axial T1-weighted magnetic resonance imaging (MRI) of the brain demonstrating a hypointense right frontotemporal cortical lesion; B: Functional MRI motor cortex mapping using blood oxygen level–dependent sequences demonstrates perilesional activation of the motor cortex and the supplementary motor area during bilateral finger tapping.
