Abstract
In this 3D video we review the case of a lower pontine cavernous malformation in a 31-year-old man who presented with hemiparesis and an abducens palsy. The cavernous malformation was completely resected through a far lateral approach and a peritrigeminal brainstem entry zone, with a significant improvement in the patient’s hemiparesis. The relevant anatomy is reviewed in detail through multiple anatomical brainstem dissection specimens, as well as high-definition fiber tractography images. The rationale for the approach is analyzed relative to other possible options, and a number of technical pearls are provided.The video can be found here: https://youtu.be/fH2Q7RjlBKQ.
Highlights
In this video we will present the far lateral approach for resection of a lower pontine cavernous malformation
The cavernous malformation presented to the surface of the pons just above the pontomedullary fissure and just superior to the left vertebral artery
The motor nuclei of cranial nerves VI and VII are found in the pontine tegmentum, whereas the basis pontis is dominated by the corticospinal tracts
Summary
0:20 Introduction In this video we will present the far lateral approach for resection of a lower pontine cavernous malformation. A CT scan revealed a hemorrhagic lesion in the left lower pons, and a T2 MRI showed the classic popcorn appearance of a cavernous malformation. The cavernous malformation presented to the surface of the pons just above the pontomedullary fissure and just superior to the left vertebral artery.
