Figure 4.5.13 Tracheal Adenocarcinoma (Feline) CT

6y FS Egyptian Mau with increased respiratory
effort and stridor. A mural mass is seen involv­
ing the caudal cervical trachea, resulting in
partial luminal occlusion (a: arrow). A CT
image cranial to the mass shows the normal
trachea (b: arrow) and the adjacent contrast‐
enhancing cervical esophagus (b: arrowhead).
Further caudally, an intensely enhancing
tracheal mass is confirmed to be mural
(c,d: arrows). Mass margins are clearly
defined, and the tracheal lumen is narrowed
at this level. Excisional biopsy revealed the
mass to be a tracheal adenocarcinoma.
