History: Respiratory Distress
•There is a mild volume of left-sided pleural effusion and scant right-sided pleural effusion.
•Decreased volume of both subsegments of the left cranial lung lobe with mild dilation of the lobar bronchi with tapering immediately adjacent to the carina.
•A vesicular emphysema pattern is distributed largely symmetrically the left cranial lung lobe.
There are findings consistent with a left cranial lung lobar torsion with mild concurrent pleural effusion. An underlying cause for a lung lobe torsion is not definitively identified in this examination.
