             3y MC Labrador Retriever with acute onset of lethargy. Transverse unenhanced (a,b) and comparable contrast­enhanced (d,e) images
             are ordered from cranial to caudal. There is a fluid‐attenuating mass within the caudal mediastinum, which crosses the diaphragm
             and extends into the retroperitoneal space (c,d: arrows). The mass extends between the peritoneum and body wall on the right side
             (d: asterisk) and peripherally and intensely contrast enhances. Biopsy confirmed that the mass was a hemangiosarcoma.
