Manifestations of venous tumor thrombus (VTT) on plain and enhanced MRI scan. A, A VTT located at the left common iliac vein (arrow) showed hypointense fillings inside the vascular lumen on T1WI sequence. B, A VTT located at the left common iliac vein (arrow) showed hyperintense fillings inside the vascular lumen on T2WI sequence, which was apparent compared with the flowing void effect of the right common iliac vein. C, A VTT located at the left common iliac vein (arrow) showed streak‐like enhancement within the filling defect on contrast enhancement
