CXR Spontaneous Pneumothorax

CXR Spontaneous Pneumothorax
20-year-old female presents with acute left sided chest pain. She has asthenic build which raises the suspicion for a spontaneous pneumothorax. Frontal CXR shows a small subtle pneumothorax characterised by a thin pleural line (b, white arrowhead) and relative lucency of the left apex compared to the right (b, ringed)
