Background:
Compared to the general population, cancer patients are more likely to suffer from cerebral ischemia, either caused by the tumor itself or by the treatments applied.
Case description:
We hereby present the clinical case of a patient treated for lung adenocarcinoma, who, years later, developed a case of the right frontal-temporal-insular ischemia secondary to leptomeningeal spread of the primary neoplasm, with an invasion of the walls of the right-middle cerebral artery and its branches.
Conclusion:
This should be considered an extremely rare form of recurrence of a primary solid tumor with clinical and radiological features that can mimic those of vascular inflammatory entities.
