MRI-guided laser interstitial thermal therapy using the Visualase system and Navigus frameless stereotaxy in an infant: technical case report.

Laser interstitial thermal therapy (LITT) is increasingly used as a surgical option for the treatment of epilepsy. Placement of the laser fibers relies on stereotactic navigation with cranial fixation pins. In addition, the laser fiber is stabilized in the cranium during the ablation using a cranial bolt that assumes maturity of the skull.

Stereotactic laser ablation for subependymal giant cell astrocytomas: personal experience and review of the literature.

Purpose: Subependymal giant cell astrocytomas (SEGAs) are rare tumors typically found in tuberous sclerosis patients. They typically grow in the region of the foramen of Monro and can occlude it, leading to hydrocephalus. Currently, gross total resection is the standard of care, with low rates of recurrence but high rates of complication, especially with larger lesions.
