We report a case of Lemierre's syndrome due to Fusobacterium nucleatum in a previously healthy 19-year-old male. This is the first case report of Lemierre's syndrome due to thrombophlebitis of the external jugular vein. The patient had a rapid clinical response to anticoagulation and antibiotics, as supported by anecdotal evidence.
CASE REPORTA 19-year-old African-American male presented in the emergency room complaining of a 5-day history of fever, rigors, sore throat, pleuritic chest pain, and productive cough with blood-tinged sputum and a 2-day history of nausea and vomiting. One day prior to admission, the patient had presented in the emergency room with the same complaints. He was treated intravenously with ketorolac (60 mg) for his pain and discharged to his home with a course of amoxicillin for a presumptive case of pharyngitis. The patient had otherwise been healthy, and past medical history was remarkable for treatment of gonorrhea and chlamydia 1 month prior. Review of symptoms was negative for headache, photophobia, and dysuria, and the patient had no history of recent travel, tick exposure, or intravenous drug use.On presentation, the patient had scleral icterus and was obviously uncomfortable. Vital signs included a temperature of 39.1°C, a regular pulse of 105 beats per minute, a respiratory rate of 20 breaths per minute, and supine blood pressure of 130 over 60. Oral examination demonstrated erythema and swelling of the posterior pharyngeal mucosa and tonsils, yet without exudates. The neck was diffusely tender to palpation. Multiple, nontender posterior cervical lymph nodes were palpable bilaterally, which the patient stated had been the case for several years. The lungs were clear to auscultation; however, the patient complained of diffuse chest tenderness to palpation. Cardiac exam results were significant for tachycardia, but no murmurs, rubs, or gallops were detected by auscultation. Abdominal exam results were negative for tenderness and for hepatosplenomegaly and other masses. Skin showed no rashes or petechiae, and the neurologic exam results were normal.Laboratory data were significant for the following: leukocyte count, 12,600/mm 3 (93% granulocytes, 2.8% lymphocytes); platelet count, 41,000/mm 3 ; sodium, 127 mmol/liter; potassium, 3.1 mmol/liter; chloride, 87 mmol/liter; bicarbonate, 29 mmol/liter; blood urea nitrogen, 26 mg/dl; creatinine, 1.4 mg/ dl; total bilirubin, 4.0 mg/dl; and lactate dehydrogenase, 260 U/liter. Hemoglobin level and hematocrit were normal at 14.0 g/dl and 41.7%, respectively. Specimens for a human immunodeficiency virus enzyme-linked immunoassay, a monospot, a hepatitis panel, and a drug screen and three sets of cardiac enzymes were drawn, and results were later returned as normal. Electrocardiogram results were significant for sinus tachycardia and high QRS voltage in chest leads V1 to V5.
