Figure 14a. Iodinated oil embolism in a 45-year-old woman with sudden dyspnea. The patient had a large primary liver carcinoma containing arteriovenous shunting and had undergone transarterial hepatic chemoembolization with a mixture of adriamycin and iodinated oil (Lipiodol; Guerbet, Roissy, France) 1 day earlier. (a) Chest radiograph obtained 1 day after chemoembolization shows patchy areas of lung nodules and consolidation bilaterally. Note also the multifocal areas of iodinated oil uptake in the liver (arrows). (b) Thin-section (1-mm collimation) CT scan (lung window) obtained at the level of the inferior pulmonary vein shows multifocal patchy areas of ground-glass attenuation in both lungs. Several high-attenuation nodules are also noted (arrows). (c) Thin-section (1-mm collimation) CT scan (targeted mediastinal window) obtained at the same level as b shows nodules with calcific attenuation in the right lower lobe (arrows), a finding that suggests iodinated oil uptake in metastatic nodules.
