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.
