Figure 4.1.13 Gastroesophageal Intussusception (Canine) CT
5y FS Keeshond with a 7‐month history of
coughing and a left cranial lung lobe mass.
A tubular soft‐tissue mass is present in the
region of the caudal esophagus on survey
radiographs (a: arrowheads). Although the
left cranial lung lobe mass is not clearly
delineated, there is increased opacity in the
cranioventral thorax. The leading edge of a
gastric intussusceptum is seen on a trans-
verse CT image (b: arrowhead) and has a
striated appearance when viewed in long
axis (c,d: arrowheads). Image d represents
a sagittal plane reformation from more
thinly collimated images than image c. The
(a) DX, LLAT (b) CT+C, TP gastroesophageal intussusception was docu-
mented and reduced at the time of left
cranial lung lobectomy.
