# Multiple Glioblastomas Ablation by Laser Interstitial Thermal Therapy (LITT): A Rare Case

## TL;DR

A patient with two brain tumors was successfully treated with laser therapy, but developed swelling that required further surgery.

## Contribution

Demonstrates the effectiveness of MRg-LITT in ablating multiple glioblastomas with no recurrence.

## Key findings

- MRg-LITT successfully cauterized two GBMs with full symptom remission.
- Post-operative imaging showed vasogenic edema and midline shift requiring emergency craniectomy.
- No tumor recurrence was observed nine months after treatment.

## Abstract

Multiple glioblastomas (GBMs) are aggressive, malignant, and sporadic brain tumors. We present the case of a 58-year-old patient with two GBMs in the right frontal lobe and associated edema. The patient presented with sudden left limb weakness accompanied by abnormal gait for five consecutive days. Magnetic resonance-guided laser interstitial thermal therapy (MRg-LITT), a minimally invasive technique that disperses thermal energy was used to cauterize the deep-seated brain lesions. Following two sessions of MRg-LITT, the patient showed full remission from symptoms. However, the disruption of the blood-brain barrier (BBB) induced vasogenic edema surrounding the necrotic GBMs. Post-operative nine-month MRI images revealed severe vasogenic edema and compression on the ventricles, shifting the midline toward the left side. Therefore the patient underwent an emergency craniectomy and continues to live with close follow-ups. Here, we established that LITT procedures were effective in cauterizing GBMs with no recurrence.
