Head and abdominal imaging findings in HCC patients with pulmonary vein shunting due to direct diaphragm and pleura invasion.

<p>A right inferior phrenic artery angiogram showed prior embolized hepatic tumor with large adjacent recurrence. An early opacified pulmonary vein branch was seen (arrow head) (A); non-contrast chest CT at 2 days after CLE showed lipiodol pneumonitis at bilateral collapsed basal lung (arrow head) (B); on head non-contrast CT there were several hyperdense spots (arrow) in addition to typical disseminated lesions of increased attenuation of CLE at the cerebral hemispheres (C) and brain stem (D). At 3 weeks follow-up, head CT of the same patient showed disappearance of the previous hyperdense lesions (E & F).
