Imaging findings and transcatheter arterial chemoembolization of hepatic malignancy with right atrial embolus in 46 patients

Figure 4 A 49-year-old man with multinodular recurrence after HCC operation, with the embolus of RA discovered at the same time. The patient underwent TACE twice. A: The portal phase T1-weighted image shows a low signal embolus entering the IVC from middle HV (arrow) (TR: 220 ms/TE: 18ms, ST: 8.0 mm); B: The coronal image shows a well-defined “bottle-gourd” -shape filling defect in RA (arrow) (TR: 3.3 ms/TE: 1.5 ms/TI: 7.0 ms, ST: 3.0 mm); C: The image after perfused Lipiodol shows a nodular and lump tumor of the right and left lobe filled with Lipiodol, which was also retained in the embolus of RA (arrow).
