Abstract
Our goal was to describe the neuroradiologic findings in hemorrhagic venous infarction related to a hypercoagulable state caused by antiphospholipid antibodies (aPA). Magnetic resonance imaging was performed on two patients with superior sagittal thrombosis related to the presence of aPA. A parenchymal region of hyperintense signal due to hemorrhagic venous infarction was demonstrated in both patients, along with abnormal signal within the thrombosed superior sagittal sinus. Hemorrhagic venous infarction may result from the hypercoagulable state related to aPA. The presence of these antibodies should be considered in the setting of otherwise unexplained dural sinus thrombosis and/or venous infarction.
