case_images: MRI of the brain revealed a solitary ring-enhancing lesion with associated increased FLAIR signal in the left thalamopeduncular region [Figure 1a]. The patient continues to do well at last follow-up [Figure 1b]. Most recently, his MRI from 47.5 months after initial biopsy and 46.9 months after LITT showed only a small cavitation with minimal enhancement and FLAIR signal, likely as a result of LITT [Figure 1b].

case_images: The laser ablation was carried out under real-time MR thermography [Figure 2a]. Immediate postoperative MRI showed diffusion restriction within the tumor and increased enhancement within the necrotic core [Figure 2b].
