For the latest tale of the unexpected from medical emergency rooms, we bring you the case of a 66-year-old man who turned up at the hospital complaining of a cough and chest pains.

Soon enough, doctors realised the patient’s internal organs were all on the wrong side of his body: his heart was on the right, liver on the left, and so on.

This condition actually has a name, situs inversus totalis, and it’s not as life-changing as you might think at first. In fact, before we had modern medical scanning tools, it’s thought most people who had this lived their lives without ever getting diagnosed.
