Pleuropulmonary blastoma in a dog—Diagnostic findings, surgical treatment and outcome

A one‐and‐a‐half‐year‐old dog was presented to our institution, with a 48‐hour history of coughing and lethargy, for investigation of a suspected spontaneous pneumothorax. Computed tomography revealed a pneumothorax and the presence of two cavitary lesions affecting the right cranial and right caudal pulmonary lobes. Following stabilisation, lung lobectomy of the affected lobes was performed via median sternotomy, and the patient recovered with no complications. Histopathological analysis of the submitted tissues identified pleuropulmonary blastoma. Repeat computed tomography 4 months post‐operatively revealed no evidence of lesion recurrence or pneumothorax. To the authors’ knowledge, this is the first report describing the computed tomography appearance and surgical management of pleuropulmonary blastoma in a dog.
