Takeaway
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.
