In the current literature, there have been cases highlighting mycotic aneurysms leading to subdural hematoma. Several others describe similar topics;however, none were caused by Abiotrophia defectiva, leading to a herniation event. Abiotrophia defectiva, while not common, is an insidious bacterium that is difficult to detect and leads to a poor prognosis. In their paper, Ding et al. described a hematoma formation from a ruptured aneurysm of the distal middle cerebral artery [1]. Similar cases include two instances published by Boukobza et al. [2]. These prior articles and our report summarizes that this diagnosis typically warrants careful evaluation of etiologies and close management of the patient.展开更多

This boy with history of rheumatic heart disease with vegetations on mitral valve and severe mitral regurgitation landed up in complications of infective endocarditis like femoral artery thrombo embolism followed by an abdominal aortic aneurysm with contained rupture. This case was successfully managed addressing two problems i.e. valve and aneurysm repair in single sitting.展开更多

However, immunocompromised hosts and older adults with complex medical conditions may develop a complicated form of bacteraemia, with a high mortality rate involving extra-intestinal foci of infection and mycotic aneurysms. We report the case of a 61-year-old man with poorly controlled diabetes mellitus, hypertension, dyslipidaemia, and congestive heart failure, who presented with unilateral left lower limb swelling, extensive deep vein thrombosis, and concomitant Salmonella bacteraemia. An oral anticoagulant and intravenous antibiotic therapy were initiated. Although the patient remained haemodynamically stable, he complained of constant left lower limb weakness and lower back pain. A computed tomography angiography scan of the thorax and abdomen revealed saccular aneurysms with contained hematoma of the left common iliac artery. The oral anticoagulant was discontinued, and an inferior vena cava filter was inserted as part of the venous thrombosis management. The patient was offered aorto-uni-iliac endovascular aneurysm repair and received intravenous antibiotic therapy, postoperatively, for six weeks. The postoperative blood cultures remained negative, and he was discharged with a course of ciprofloxacin administered orally. However, three months after the surgery, the patient died of recurrent septicaemia. This case illustrates the importance of remaining vigilant for potential endovascular complications of Salmonella bacteraemia, such as mycotic aneurysms and deep vein thrombosis, among high-risk patients. Further, this case highlights the challenges of eliminating Salmonella bacteraemia and its related complications, albeit treating it with both a prolonged course of medical therapy and surgical intervention.展开更多
