title: Pleuritis and pneumonia attributed to a conifer twig in a bronchus of a horse.
abstract: A conifer twig was responsible for severe fibrinopyogranulomatous adhesive pleuritis and pneumonia in a horse. At necropsy, the twig was found in a terminal bronchus and extended into the lung parenchyma, through the pleura, and into the accumulated exudate. Inhalation of plant material may be a more common cause of pleuritis than previously recognized. Meticulous examination at necropsy would be necessary to make the diagnosis.
