ABSTRACT
A 19-year-old male patient was referred by his general practitioner with a new 'cardiac murmur'. For 1 week, he had been able to provoke a clicking sound, which was in time with his heart beat and originated from his chest. The physical examination and laboratory tests were normal. The sound was initially interpreted as most likely due to a valve condition such as mitral valve prolapse, but a transthoracic echocardiogram was normal. A cardiac CT was obtained, which showed left-sided ventral pneumothorax.The Hamman's sign is a loud precordial pulse synchronous sound, which is often postural. It is pathognomonic for left-sided pneumothorax or pneumomediastinum. Hamman's sign as a presenting symptom is rare, but if present is key to diagnosis. The awareness of rare clinical findings is important and will prevent unnecessary diagnostic tests.
