Magnetic resonance-guided thermal therapy for posterior fossa neoplasms


  • Magnetic resonance-guided laser interstitial thermal therapy (LITT) is effective for treating posterior fossa pathology despite a smaller average target size than that reported in the supratentorial space.

Why this matters

  • Magnetic resonance-guided LITT, a minimally invasive technique, is increasingly used to treat intracranial pathologies; however, its use in the posterior fossa is limited, largely due to the smaller size and complexity of this region.

  • The demonstrable efficacy and safety profile of LITT in posterior fossa neoplasms potentially provides a minimally invasive therapeutic alternative for these patients, associated with shorter hospitalization and significant overall local control rates, although further study is required to develop consistency of technique and replicability.
