Lung lobe torsion (LLT) results from a displacement and twisting of a lung lobe around its bronchovascular pedicle. This relatively rare disorder affects dogs, cats, and humans.
Etiologies include primary (i.e., spontaneous) and secondary torsion due to thoracic trauma, pleural space disease, thoracic surgery, pulmonary parenchyma disease, and diaphragmatic hernia repair.
Although both spontaneous and secondary torsion have been described in small-breed dogs, a spontaneous LLT followed by recurrence of a spontaneous LLT >2 years later has not been documented.
This article describes the presentation, diagnosis, management, and outcome of a pug with recurrent spontaneous LLT.
