A 56 y/o male with known cardiac amyloidosis, abdominal pain and nausea. a CT of abdomen showed thickening of the left ventricle myocardium related to amyloid deposition (dotted arrow). Additionally, there are gastric distension (asterisk) and pneumatosis (thin arrows).

Gastric emphysema and ischemia were found at surgery
