Pulmonary and cerebral lipiodol embolism after transcatheter arterial hemoembolization in hepatocellular carcinoma

Figure 4 A 36-year-old man with cerebral lipiodol embolism. A: Axial T2-weighted imaging (T2WI); B: Biffusion-weighted imaging (DWI); C: Apparent diffusion coefficient (ADC); D: Follow-up DWI. A, B and C obtained 57 h after the second TACE, and D obtained 5 wk after the second TACE. T2WI and DWI (A, B) demonstrated multiple high-signal lesions on the bilateral frontal and parietal lobe. The corresponding lesions showed a low signal area on the ADC map (C). A follow-up DWI revealed no obvious abnormal signal (D).
