ABSTRACT
A 29-year-old man was admitted to hospital following complaints of chest pain. He described left-sided, sharp chest pain, which had come on gradually over 2–3 days. He thought the pain may be worse on deep inspiration and said that he noticed it more when trying to sleep at night. There were no associated features, such as sweating, palpitations or nausea. He complained of a dry cough and flu-like symptoms over the preceding fortnight, with mild swelling of his knees and a rash on is left arm that had now resolved. He worked as a website designer in London and drank around 20 units of alcohol per week. He had never smoked and used no herbal or recreational drugs. He had no recent sexual partners. He had not travelled abroad for several years but did spend most weekends walking in the Scottish Highlands.
