A 70-year-old man falls off his moped and now complains of chest pain and difficulty breathing

A 70-year-old man falls off his moped and now complains of chest pain and difficulty breathing. He is tachypnoeic with a respiratory rate of 24; his other vital signs are normal. On examination, chest expansion is reduced on the left, breath sounds and vocal fremitus are quieter over the left hemithorax, and percussion is dull-sounding on the left but resonant on the right; there is no tracheal deviation. What diagnosis would be most consistent with this man’s clinical presentation?
