ABSTRACT
A 45-year-old man was referred to the emergency department in early January by his general practitioner with a suspected pulmonary embolism. He described a 12-day history of fevers, rigors, night sweats, right-sided chest pain on deep inspiration and right-sided abdominal pain. Four days earlier, he had started a course of oseltamivir (for presumed influenza) and had been feeling nauseated with several episodes of vomiting since then. He had no past history, aside from an appendectomy in childhood, and took no regular medications.
