Abstract

This
is a first case of mycotic aneurysm due to Streptococcus
constellatus in a 58 years old male patient with diffuse large B cell
lymphoma. A mycotic aneurysm is a rare but life threatening and potentially
fatal sequela of bacteraemia. A 58-year male patient initially presented with
sepsis after 7 days of chemotherapy. No clear focus of sepsis was found. Blood
culture grew Streptococcus constellatus.
He received appropriate antibiotic and discharged well. He represented after 5
days with excruciating intrascapular and chest pain. This patient with
haematology malignancy had radiologically, surgically and histologically
confirmed mycotic aneurysm that involved ascending aorta which contained
pseudoaneurysm. Patient was treated excision of the infected tissue and aortic
graft, and long term antibiotics. This rare case highlights that the high
clinical suspicion in patients presenting with possibly mycotic aneurysm is a
critical tool in addition to perfect surgical treatment and medical treatment
with adequate antibiotics. J Microbiol
Infect Dis 2017; 7(4):213-216
