Findings

Thorax - ventrodorsal and opposite lateral radiographs are available for review.

A chest tube is in place, entering the thorax at the left 8th intercostal space and coursing axially and cranially, terminating at the level of the third ribs. There is a small volume of gas in the pleural space, most pronounced on the left with retraction of the lung lobes from the body wall.

There is a mild to moderate unstructured interstitial pulmonary pattern in the caudal subsegment of the left cranial lung lobe and left caudal lung lobe, with a focal region of alveolar pulmonary pattern in the left caudal lung lobe.

There is a moderate leftward mediastinal shift of the cardiac silhouette. The cardiovascular structures are otherwise normal. The esophagus contains a small volume of gas cranially and ill-defined fluid opaque material caudally.

There is a small gas bubble superimposed with the falciform fat ventral to the liver on the right lateral projection.

The musculoskeletal structures included in collimation are normal.

Diagnosis

- Small volume pneumothorax.

- The multifocal pulmonary pattern is most likely attributed to atelectasis. Underlying pulmonary abnormality can not be completely ruled out. A cause for the pneumothorax is not identified.

- Aerophagia and caudal esophageal fluid (consider transient swallowing or gastroesophageal reflux).

- Equivocal pneumoperitoneum versus superimposition of subcutaneous gas.

Discussion

A CT was performed to rule out underlying causes of pneumothorax and was mostly unremarkable.

Notes

This case was initially seen by Dr Griffith on clinics.
