    BackgroundTransient tumor attack is a rare but well-known phenomenon. Described by Ross in 1983, it demonstrated a transient ischemic attack-like picture in patients with intracranial mass lesions. Usually these attacks were recognized at sites anatomically away from the primary lesion that were not explained by primary mass effect of the lesion. The exact pathophysiology of such transient tumor attacks is postulated to be due to either a vascular steal phenomenon or compression of a vessel or localized prothrombotic state.Case DescriptionHere we describe a case who was being evaluated for a lacunar stroke involving the lateral geniculate body, and a surprising finding of left intraventricular meningioma was detected.ConclusionsWe try to shed some light on the pathophysiology of this unusual phenomenon.Copyright © 2019 Elsevier Inc.
