Arms mimicking pleural thickening on CXR

Case contributed by Assoc Prof Craig Hacking


Acute left shoulder pain. Recent left arm IVDU.

Patient Data

Age: 45 years
Gender: Male

The lungs are clear. No pneumothorax or pleural effusion. Bilateral smooth apparent pleural thicking in the lateral lower zones and costophrenic angles are caused by the medial aspects of the arms by the patient's side. Cardiomediastinal contours are within normal limits. No fracture identified.

Case Discussion

If the patient's arms are not flexed or abducted off the lateral chest wall, they may mimic pathology such as pleural thickening.
