    I would recommend observation and close follow-up.

  • Pieromaria Bianchi

    No adjuvant therapy, just periodical MRI control. I would suggest bimonthly MRI at least for the first year

  • Simon Khagi

    Serial MRI surveillance every 2-3 months. I would also recommend NGS of the tumor specimen.

  • Fabio Trippa

    I agree with previous comments. At this time I would recommend close follow-up.

    Glioneuronal tumors occur more commonly in children than in adults, are often lower grade, frequently associated with seizures, and a significant number are characterized by BRAFV600E dysregulation. The exact management following surgery remains ill-defined; a recent report from St. Jude's suggested that "high-risk" can be defined as diffuse astrocytic histology and/or midbrain/thalamic location" and speculated that post-operative radiotherapy might be beneficial in such a situation. This patient does not have such high risk features and observation with surveillance is a very reasonable strategy.

    The patient was observed and 2 month MRI brain was read as stable. However, repeat MRI 2 months later showed progression with a larger area of enhancement measuring 18 x 16 x 16 mm with increased rCBV, without significant surrounding edema. How would you proceed with management now?
