Hypertranslucency of lung unilaterally is seen on all except –: (A) Pnetunothorax, (B) Resection of mammary gland, (C) Pulm art. obstruction, (D) Pneumonectomy
Answer is D. Pneumectomy produces opaque hemithorax (not hypertranslucent).
Pneumothorax, resection of the mammary gland (mastectomy), and pulmonary artery obstruction (Pulmonary embolism) produce unilateral hypertranslucency.
