Cerebral and pulmonary embolisms after transcatheter arterial chemoembolization for hepatocellular carcinoma

Figure 1 Enhanced abdominal CT scan obtained after second chemoem-bolization shows a 15 cm × 12 cm capsulated HCC with necrotic change occupying the right hepatic lobe. The right dome of mass revealed heterogenous enhancement adjacent to the diaphragm, suggesting a viable portion (arrow).

Figure 2 A brain CT scan without contrast obtained 7 h after chemoembolization shows multiple increased attenuated lesions in both cerebral hemisphere, consistent with deposition of iodized oil.

Figure 3 A chest CT scan obtained 7 h after chemoembolization shows lipiodol oil dense depositions (arrow) at right basal lungs.

Figure 4 Diffusion-weighted MR images obtained 48 h after TACE shows multiple hyperattenuating and hypertensive punctate-patchy lesions in both cerebral hemispheres.
