A minimally invasive neurosurgical procedure that uses MRI-guided laser energy to precisely destroy abnormal brain tissue such as tumors, seizure foci, or radiation necrosis. It’s often used as an alternative to open brain surgery.
Symptoms:
LITT is used to treat conditions causing seizures (e.g., epilepsy), brain tumors (gliomas, metastases), hypothalamic hamartomas, and radiation necrosis. Symptoms may include seizures, headaches, neurological deficits, or tumor-related complications.
A laser probe is inserted through a small skull opening and guided by real-time MRI to the target area. Controlled heat ablates the abnormal tissue while sparing healthy brain structures. Most patients go home within 24–48 hours and recover quickly with minimal pain and scarring.
