Plain-English summary
In a study involving 16 dogs and 3 cats, veterinarians used a technique called ultrasound-guided fine-needle aspiration (FNA) to take samples from lung masses or areas of lung consolidation that were seen on X-rays. The results from these samples were confirmed through further testing or by identifying a specific fungus called Blastomyces. The FNA was very effective, correctly identifying cancer in 10 out of 11 pets without any false positives, and it also helped diagnose infections in some animals, including blastomycosis in 5 out of 6 cases. Most pets needed sedation for the procedure, but there were no complications. Overall, this method was found to be safe, affordable, and reliable for diagnosing lung issues in dogs and cats.
Abstract
Ultrasound-guided fine-needle aspiration (FNA) of the lung was performed on 16 dogs and 3 cats with consolidated pulmonary lesions or masses identified on thoracic radiographs. The cytologic results from the FNA were confirmed by histopathology, response to treatment, or microscopic identification of Blastomyces organisms. Neoplasia was identified correctly by FNA cytology in 10 of 11 animals, and no false positive results occurred, yielding a positive predictive value of 100%. Of 8 animals with infectious disease, 5 of 6 had blastomycosis and 1 had a bacterial infection, based on cytologic evaluation. Eight animals required sedation for the procedure, and none had clinical complications. We conclude that ultrasound-guided FNA of pulmonary mass lesions is an inexpensive, safe, and accurate method for diagnosing blastomycosis or neoplasia, especially carcinomas, in dogs and cats.
