The dyspnoea was persistent, exertional and had progressively worsened over this period of 3 years, it was currently grade 2 on the modified Medical Research Council (mMRC) grading. He was a never-smoker and there was no history of environmental tobacco smoke or exposure to noxious particles or history of illicit drug abuse. Past medical and surgical history was not significant. There was no history of significant respiratory infections during childhood and there was no history of anyone in his family with similar complaints.Differential diagnoses of unilateral hyperlucent lung are expansive, ranging from soft tissue to pulmonary parenchyma. A systematic approach to interpretation of radiography guides us in quick localisation of the anatomical site of involvement. https://bit.ly/3fNy4vT ER -
