Resection of a left insular cavernoma aided by a simple navigational tool. Technical note

Area of Science:

• Neurosurgery
• Medical Imaging
• Neurology

Background:

• Cavernous malformations (cavernomas) management depends on lesion location.
• Resection of dominant insular lobe cavernomas requires neuronavigation.
• Standard neuronavigation has drawbacks: cost, time, and brain shift inaccuracy.

Observation:

• A novel technique, magnetic resonance imaging-based corticotopography, was used.
• This method was applied to a left dominant insular cavernoma resection.
• The technique is unaffected by intraoperative brain shift.

Findings:

• Successful removal of a left dominant insular cavernoma was achieved.
• Magnetic resonance imaging-based corticotopography proved effective.
• This technique offers a simple and inexpensive alternative to standard neuronavigation.

Implications:

• Corticotopography may be a viable alternative for specific brain lesion surgeries.
• This navigation method could benefit selected cases of subcortical brain lesions.
• Potential for reduced costs and improved accuracy in neurosurgical navigation.
