5y MC Cocker Spaniel with persistent pulmonary infiltrates in the left caudal lung lobe. Unenhanced (a–c) and contrast-enhanced
(d–f,h,i) transverse images are ordered from cranial to caudal. There is increased opacity in the left caudal lung lobe, with a central
hyperattenuating linear structure that can be followed from the thorax to the ventral gastric wall (a–c: arrow). On contrast‐enhanced
images, the pulmonary infiltrates are intensely enhancing with a central lucent region of fluid attenuation (d,i: arrow). The hyperattenuat-
ing structure remains visible within the fluid tract and can be followed on the sagittal image through the diaphragm (g: arrows). The
gastric wall has a focal thickening where the foreign body originates (h,i). A bamboo skewer was surgically removed.
