We present a case that is most likely Lemierre's syndrome. A 19-year-old man presented to us with -common-cold-like symptoms, which he had had for 2 days, such as slight fever, general malaise, anorexia, sore throat, and headache. Eight days after the onset of these symptoms, he died of brain herniation due to cerebral venous thrombosis associated with micro-abscesses detected in pathological examination.
