Stroke secondary to leptomeningeal carcinomatosis with radiologic signs of arterial invasion

Abstract

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.
