Bottom Line: A 3-year-old, intact female Pomeranian presented with a 1-month history of coughing.Thoracic radiography showed focal infiltration of the left cranial lung lobe and widening of the cranial mediastinum.There was no apparent underlying etiology for the condition.

ABSTRACT
A 3-year-old, intact female Pomeranian presented with a 1-month history of coughing. Thoracic radiography showed focal infiltration of the left cranial lung lobe and widening of the cranial mediastinum. Subsequent computed tomography revealed torsion of the caudal segment of the left cranial lung lobe, which was confirmed by exploratory thoracotomy. There was no apparent underlying etiology for the condition. To the authors' knowledge, this is the first report of lung lobe torsion in this breed and the first detailed CT imaging report for segmental lung lobe torsion.

Thoracic radiographs (A, B) and longitudinal intercostal ultrasonogram (C) of the left cranial thorax. In the lateral view (A), there is increased soft tissue opacity in the cranial thorax with dorsal elevation of the intrathoracic trachea. In the ventrodorsal view (B), there is mediastinal shift to the left and widening of the cranial mediastinum. An echogenic mass (C, asterisk) was observed near the large blood vessel.

Mentions: A 3-year-old, intact female Pomeranian was referred to us with a 1-month history of coughing. At the referring hospital, the dog had been treated with antibiotics for 1 week, but there was no response. On presentation, the dog showed a normal status but exciting, and it showed intermittent coughing (sounded like a goose honking). The results of laboratory examinations (complete blood count, serum chemistry and coagulation time) were within the normal range, except for increased levels of serum alanine aminotransferase (162 µ/l; reference range, 10–100 µ/l), aspartate aminotransferase (111 µ/l; reference range, 0–50 µ/l) and glucose (172 mg/ dl; reference range, 74–143 mg/dl). Orthogonal radiographic views were obtained (Fig. 1A and 1BFig. 1.
