Salmonella-Induced Mycotic Aneurysm: A Rare Cause of Vascular Emergency

Abstract

Mycotic aneurysm is a rare but life-threatening vascular complication of systemic infections. Salmonella species commonly cause gastrointestinal infections in humans, but in rare instances, they lead to serious complications, such as mycotic aneurysms, which are potentially fatal. The mortality rates are high due to the risk of rupture without timely intervention. The clinical presentation is often variable, and an early diagnosis requires a high index of clinical alertness. We report a case of a mycotic aneurysm secondary to Salmonella enteritidis infection in an elderly man, which resulted in a rapid clinical deterioration and fatal outcome. This case highlights the need for early evaluation and prompt intervention in elderly patients with non-typhoidal Salmonella bacteremia for possible endovascular infections.
