Abstract
Purpose
Nearly a quarter of neurofibromatosis type 1 (NF 1)- associated diencephalic low-grade tumors are refractory to chemotherapy. Addition of alternative treatment options with laser interstitial thermal therapy will have a positive impact on the outcome of these patients.
Methods
We report on two illustrated cases of pediatric NF1- associated, chemoresistant, WHO grade 1 pilocytic astrocytomas treated with laser interstitial thermal therapy (LITT).
Results
Both tumors responded favorably to LITT.
Conclusion
LITT should be considered as a treatment option for chemoresistant deep-seated NF1-associated low-grade gliomas.
