From: Isolated cortical vein thrombosis after nitrous oxide use in a young woman: a case report
Head MRI ten days after admission showed isolated cortical vein thrombosis (arrow head) over the frontal cortical surface and expanding hematoma and edema (double arrow head) that caused cingulate herniation in the sagittal, coronal and axial section (a-c) on T2 SPACE sequence. The sizes of thrombosis (arrow head), hematoma and edema (double arrow head) continuously decreased on T1 CUBE sequence after five (d-f) and twelve (g-i) days of anticoagulation, respectively
