Not your typical pneumonia!

1 of 2 DESCRIPTION A 52-year-old gentleman presented to accident and emergency with a 1-week history of sore throat. He had felt generally unwell and feverish the day prior to admission with a cough productive of yellow sputum. On examination he looked lethargic, had a temperature of 38°C and was tachycardic. Medical history included coarctation of the aorta repair in adolescence which subsequently became aneursymal. This was treated with endovascular thoracic aortic stent insertion 15 months prior to admission. Chest radiograph ( fi gure 1A ) demonstrated a left upper-lobe consolidation and an air-fl uid level in the adjacent aorta. Urgent CT ( fi gure 1B ) confi rmed an air-fl uid level within the aneurysm sac. He was treated for aortic stent infection and associated pneumonia with broad-spectrum intravenous antibiotics. Given the complicated thoracic surgical history, we elected for a conservative approach with CT-guided transpulmonary drainage of the collection via the left posterior thoracic wall and concomitant insertion of a prophylactic chest drain. Approximately 25 ml of pus was aspirated, which grew Staphylococcus aureus and Group A β-haemolytic Streptococcus. The aortic aneurysm sac drain was fl ushed on a daily basis. Antibiotics were rationalised to intravenous clindamycin (penicillin allergic) for 3 weeks. He was discharged home 1 month after admission and remains well on oral antibiotics. Thoracic aortic stent infection is an uncommon but serious complication of endovascular insertion. 1 To our knowledge, this is the fi rst case of it presenting as pneumonia. Although the literature favours surgical rather than conservative management of the condition, 1 we cite another case of successful conservative treatment.
