Oh, the joy of navigating the labyrinth that is epilepsy surgery evaluation! Here we have a riveting tale of three pediatric patients, each a conundrum wrapped in a mystery inside an enigma, thanks to their negative MRI results and seizure onset zones playing hide and seek near those oh-so-precious eloquent areas. The plot thickens with a twist – these young adventurers had already braved the treacherous waters of traditional open surgery or dabbled in the arts of SEEG-guided radiofrequency thermocoagulations (RF-TC), only to find their seizures making a grand, unwelcome encore.

But fear not! Our intrepid researchers, armed with the magic wand of Magnetic Resonance-guided laser interstitial thermal therapy (MRg-LiTT), embarked on a quest to vanquish the beast of drug-resistant epilepsy. With the precision of a master chess player, they planned their laser probes’ trajectories, diving deep into the brain’s mysteries to tackle Focal Cortical Dysplasia type II – the most common villain behind the facade of a negative MRI.

Our heroes, aged merely 47 months at the onset of their epic journey, faced the dragon of MRg-LiTT at an average age of 12 years. And lo! Two emerged victorious with an Engel class Ia outcome, while the third, though slightly less triumphant, still achieved a commendable Engel class Ib. Alas, in every tale of heroism, there is a hint of tragedy – one brave soul encountered the dreaded beast of extradural hematoma.

So, what have we learned from this saga? That combining SEEG and MRg-LiTT is akin to wielding Excalibur and Mjölnir at the same time – a formidable strategy against the dark forces of complex epilepsy cases. It appears that specific SEEG patterns and a previous victory in the battle of RF-TC can herald a favorable outcome. Thus, our tale concludes with a glimmer of hope, a testament to the relentless pursuit of innovation in the face of adversity.
