Mycotic Aneurysm in Salmonella enteritidis Infection: A Fatal Complication.

Mycotic aneurysms are rare but severe complications that can arise from systemic bacterial infections, including those caused by Salmonella species. These aneurysms can progress rapidly and are associated with high mortality. A 62-year-old man with poorly controlled type 2 diabetes mellitus presented to the hospital in septic shock. The blood culture grew Salmonella enteritidis. A computed tomography angiogram showed a ruptured mycotic aneurysm of the infrarenal abdominal aorta. Despite antibiotic therapy and supportive care, the patient's condition rapidly deteriorated, resulting in his death, most likely due to aneurysm rupture. This case highlights the importance of vigilance in patients with Salmonella bacteremia, particularly in high-risk individuals, such as the elderly and people with underlying cardiovascular diseases. Early imaging and timely intervention are critical for improving outcomes and preventing fatal complications, such as aneurysm rupture.
