- The study compares CT characteristics of pulmonary metastases from different primary cancers in dogs.
- CT features like ill-defined margins, cavitary lesions, and bronchial thickening correlate with specific tumor histotypes.
- Features such as a higher number of nodules, SPLASH sign, and halo sign are indicative of hemangiosarcoma (HSA).
- Larger nodule size (>1 cm), air bronchograms, and thoracic lymphadenomegaly are seen in histiocytic sarcomas.
- CT features of lung metastases can help prioritize neoplasia histotype in dogs when the primary tumor is not obvious.
