Description:

This soundless video of surgery for excision of a right insular low-grade glioma shows dissection of the M1/M2 branches of the middle cerebral artery and sub-cortical stimulation. The patient is a 39-year-old woman who presented with simple partial seizures. She experienced a rising feeling in her abdomen followed by olfactory hallucinations (see the pre-op MRI by clicking here). Post-operatively, she suffered simple partial motor seizures that involved the left side of her face. These were adequately controlled with anti-convulsant drugs (see the post-op MRI by clicking here). For a review of low-grade gliomas, please refer to the following reference: Preoperative prognostic classification system for hemispheric low-grade gliomas in adults: Clinical Article.
