April 2, 2020 By Allison Zwingenberger

This week’s case is a 12-year-old female neutered Australian Shepherd with lethargy, anorexia, panting, and coughing.

Findings

There is increased density in the perihilar region resulting in ventral deviation of the mainstem bronchi and carina. Increased pulmonary opacity is present caudodorsally with a interstitial to alveolar infiltrate in the left and right caudal lung lobes. The cardiac size and pulmonary vasculature are within normal limits. There is hepatosplenomegaly visible within the cranioventral abdomen.

Diagnosis

  • Lymphoma

Discussion

Multicentric lymphoma usually affects the liver, spleen, thoracic lymph nodes, and peripheral lymph nodes. Occasionally, it will also cause interstitial infiltrates of the lungs themselves. Unlike other tumors, lymphoma very rarely causes nodular metatases. Infiltrates such as these will often resolve quickly if the animal responds to chemotherapy.

    Hi Alison, Thank you for another interesting case.
    I would like to ask a question if you get a chance: please:
    – is there dilation of the left main bronchi ias it does not taper down as the right one?
    -Why is there increased left airways wall opacity? Is that artefact?
    – The thoracic lymphnode does not seem to b enlarged on the xrays?What would be other differental diagnosis except lymphoma? Is it really definite diagnosis with the findigs discribed above?
    – Would right side heart failure be possible with findings? Thank You
    Kind regards
    Anna
