Area of Science:

  • Neurosurgery
  • Neurology
  • Vascular Surgery

Background:

  • Intramedullary spinal cavernoma is a rare vascular malformation, accounting for 5-12% of all spinal vascular tumors.
  • Clinical presentation varies, including acute neurological deterioration, recurrent deficits, or slow progression.
  • Surgical resection is indicated for symptomatic and accessible lesions.

Purpose of the Study:

  • To present a refined surgical technique for the complete resection of intramedullary spinal cavernoma.
  • To highlight the utility of intraoperative electrophysiological monitoring and real-time ultrasound guidance in this procedure.

Main Methods:

  • A microsurgical technique for complete resection was employed.
  • Intraoperative electrophysiological monitoring was used to assess neural function during surgery.
  • Intraoperative real-time ultrasound guidance facilitated precise localization and dissection of the lesion.

Main Results:

  • The presented surgical technique allowed for complete resection of the intramedullary cavernoma.
  • Intraoperative monitoring and ultrasound guidance were crucial for achieving safe and total removal.
  • The management of this rare pathology was further elucidated.

Conclusions:

  • Complete microsurgical resection of intramedullary spinal cavernoma is feasible and effective.
  • Intraoperative electrophysiological monitoring and ultrasound are valuable adjuncts for safe and complete tumor removal.
  • This technique offers a viable option for managing symptomatic intramedullary cavernomas.
