ABSTRACT
We describe the case of a 32-year-old woman with focal drug-resistant epilepsy, who underwent surgical resection of a cerebral cavernous malformation (CCM), previously treated with laser interstitial thermal therapy (LITT), after experiencing seizure recurrence. Histological findings after LITT have been rarely described. We report and discuss neuropathological findings to explain post-LITT seizure recurrence, with a focus on extensive hemosiderin deposition and a minimal residue of the original CCM. This illustrative case may aid the comprehension of histological bases underlying the LITT failure in seizure relief.
