Objective:

This study demonstrates the utility of a newly-developed moveable 1.5 Tesla intraoperative MR imaging system using a case report of a multi-lobulated parafalx meningioma.

Clinical Presentation:

A 43-year-old female presented with progression of a multi-lobulated anterior parafalx meningioma several years following resection of a large left frontal convexity meningioma.

Intervention and Technique:

Surgical excision of the lesion was undertaken. Following apparent total resection, intraoperative MR imaging revealed two residual dumbell shaped lobules. Using these updated MR images, the tumour was readily identified and removed.

Conclusion:

The moveable 1.5 Tesla intraoperative MR system used in the present case provides rapid, high resolution MR images during neurosurgical procedures. Moving the magnet out of the surgical field during surgery permits the use of all standard neurosurgical instruments. The ease of use and quality of images combined with minimal interference on well-established surgical techniques makes this system a valuable adjunct in the neurosurgical treatment of intracranial disease.

Résumé

RÉSUMÉObjectif:

Cette étude démontre l’utilité d’un nouveau système mobile d’imagerie par resonance magnétique (IRM) Tesla 1.5 au moyen d’un cas de méningiome multilobulé situé près de la faux du cerveau.

Préntation clinique:

Une femme de 43 ans s’est présentée avec un méningiome antérieur multilobulé situé près de la faux du cerveau, évoluant depuis plusieurs années suite à la résection d’un gros méningiome de la convexité frontale gauche. Intervention et technique: Une excision chirurgicale de la lésion a été entreprise. Suite à une résection apparemment totale, l’IMR extemporanée a révélé deux lobules résiduels en forme d’haltères. La tumeur a alors été facilement identifiée et excisée suite à l’information fournie par ces images extemporanées.

Conclusions:

Le système mobile d’IMR extemporanée Tesla 1.5 utilisé dans ce cas fournit rapidement des images de haute résolution pendant des interventions neurochirurgicales. L’aimant est déplacé hors du champ opératoire pendant la chirurgie, ce qui permet l’utilisation de tous les instruments neurochirurgicaux standards. La facilité d’utilisation et la qualité des images combinées à une interférence minimale dans les techniques chirurgicales standards font de ce système un instrument d’appoint précieux dans le traitement neurochirurgical des pathologies intracrâniennes.
