Cerebral Infarction Secondary to Vascular Infiltration of Glioblastoma Confirmed in High-Resolution Vessel Wall MRI

ABSTRACT

Acute cerebral infarction secondary to glioblastoma is rarely reported, and its mechanism is still controversial. Vascular infiltration of malignant cell, direct mass effect and local procoagulant effect were considered as main pathophysiology. We report a case of glioblastoma-related cerebral infarction documented by high resolution vessel wall magnetic resonance imaging, which reveals concentric enhancement of arterial wall and intraluminal thrombus without direct compression. These findings suggest tumor cell infiltration of intracranial vessels is one of the important mechanisms of glioblastoma-related cerebral infarction.
