Plain-English summary
This study looked at the CT scan results of pulmonary lymphoma, a type of cancer, in one dog and two cats. The dog had clear areas of lung consolidation and nodules, along with swollen lymph nodes in the chest, and also had nodules in the kidneys, all diagnosed as B cell lymphoma. One of the cats had a similar lung issue with a swollen lymph node in the chest but no other problems, while the other cat had a mass in the throat and multiple lung nodules, both also diagnosed as lymphoma. A key feature seen in all three cases was the presence of well-defined lesions with clear air passages and blood vessels visible in the lungs. Overall, the findings confirmed that all three pets had pulmonary lymphoma.
Abstract
This case series assessed CT findings of pulmonary lymphoma in a dog and two cats. The dog (Case 1) showed defined consolidation and nodules with enlarged sternal and mediastinal lymph nodes. Air bronchogram and distinct pulmonary vessels were observed within the lesion. Several nodules were also found in the kidneys. Pulmonary and kidney lesions were diagnosed as B cell lymphoma. One cat (Case 2) showed well-defined consolidation with an enlarged tracheobronchial lymph node. Air bronchogram and distinct pulmonary vessels were also observed in the lesion. No additional lesions were detected. The pulmonary lesion was diagnosed as B cell lymphoma. Another cat (Case 3) showed a nasopharyngeal mass and multiple well-defined pulmonary nodules without lymphadenomegaly. Pulmonary nodules and the nasopharyngeal mass were diagnosed as lymphoma. In Case 3, T/B classification was not performed. Of three pulmonary lymphoma cases, the distinguishing imaging feature was a well-defined lesion with distinct air bronchograms, pulmonary vessels and homogeneous enhancement.
