POCUS Finding of Portal Venous Gas: An Unusual Consequence of an Amyloid Dysmotility Related Bezoar.

A thickened left ventricle and recurrent pericardial effusion were found. Unexpectedly, on scanning the inferior vena cava (IVC), extensive portal venous gas was identified, a finding previously described as a "meteor shower".
