Male, 29 years old, history double up see with drop attacks, image guidance during laser ablation. Selected sequences are provided for guidance during laser ablation.Two laser ablation fibers are in place, one of which approaches from the right posterior parietal region coursing anteriorly and inferiorly to track along and terminate within the body of the right corpus callosum; the second approaches from the right frontal region and tracks inferiorly and posteriorly through the right corpus callosum genu and terminating at the level of the rostrum.On postcontrast images, a blush enhancement is seen along the distal aspects of both laser fibers compatible with procedure-related disruption to the blood brain barrier. Again seen is encephalomalacia of the anterior right temporal lobe along with evidence of multiple prior bilateral craniotomies.
Image guidance during laser ablation reveals the placement of two laser fibers, one which tracks along the right corpus callosum body, while the other tracks along the right corpus callosum genu and rostrum. Postcontrast images reveal a blush enhancement along the distal aspects of both fibers compatible with procedure-related disruption of the blood brain barrier.
