We report a case of a 75-year-old man who had been complaining of fever and pelvic pain for 3 weeks. First angio-computed tomography (CT) characteristics and blood culture led to suspicion of a pneumococcal-infected aortic aneurysm, which however was not confirmed by the surgeon. The abdominal infectious aortitis caused by Streptococcus pneumoniae was affirmed by a second angio-CT performed 7 days later. Without further delay, the patient underwent surgery for resection of mycotic aneurysm and in situ reconstruction with aortobiiliac homograft, in association with antibiotics. He died 10 days after the surgery as a result of severe sepsis in a polyvalent intensive care unit. This case report highlights the severity of this pathology. We reviewed the relevant literature related to Streptococcal pneumoniae mycotic aneurysm located in the abdominal aorta, including 29 more cases. Various microorganisms have already been associated with mycotic aneurysms, including S pneumoniae. Infectious aortitis remains a rare disease. It is extremely important to establish an early diagnosis but it may be delayed because clinical manifestations are usually nonspecific. However, if left untreated it is always lethal. Antibiotic in combination with complete surgical excision of the infected aorta is the treatment of reference. This therapeutic association dramatically improved patient survival.
