Case Reports
Staged Laser Interstitial Thermal Therapy (LITT) Treatments to Left Insular Low-Grade Glioma.
Low-grade insular gliomas remain challenging tumors for aggressive resection because of the numerous functional and vascular structures surrounding them. Because of the potential morbidities associated with open surgical resection, less invasive techniques may confer a more optimal balance between cytoreduction and surgical complications. For this reason, we evaluated the use of laser interstitial thermal therapy (LITT) for resection of a dominant hemisphere oligodendroglioma World Health Organization (WHO) grade II in a 68-yr-old patient by use of multiple staged surgeries for its resection. ⋯ This case report demonstrates successful use of LITT for staged surgeries to treat a left hemisphere-dominant insular lesion. This establishes the use of LITT as a viable, minimally invasive option to treat tumors that are difficult to access or pose concerns for increased morbidity through an open surgery.

The incidental discovery of brain lesions in children has increased due to greater utilization of neuroimaging. Standardized surveillance and management guidelines following the discovery of such lesions remain nonexistent. ⋯ Most incidental brain lesions indeterminate for neoplasm have an indolent, benign course. For asymptomatic patients with radiologically stable lesions, we recommend conservative management with MRI and clinical surveillance at 6, 12, 24, 36, and 60 mo after detection.
