Contralateral transcallosal transfalcine approach for bilateral intra-extraventricular anaplastic ganglioglioma via 'the trans-tumoral route': a technical case instruction.

The management of bilateral, biventricular lesions such as AGG requires innovative surgical approaches tailored to individual patient characteristics. The case highlights the efficacy of a transtumoral approach in achieving maximal safe resection while minimising neurological sequelae. Moreover, it underscores the importance of comprehensive treatment strategies, including adjuvant therapies, in addressing aggressive histological variants of gangliogliomas.
