# Methicillin-Sensitive Staphylococcus aureus Bacteremia With Multiple Lung Abscesses: A Case Without an Apparent Source of Septic Emboli

## TL;DR

A young man developed severe lung infections from methicillin-sensitive Staphylococcus aureus without a clear source of infection.

## Contribution

This case highlights the rare occurrence of MSSA bacteremia with lung abscesses without identifiable septic emboli sources.

## Key findings

- The patient had MSSA bacteremia with multiple lung abscesses.
- No source of septic emboli was identified despite thorough evaluation.
- Both TTE and TEE showed no cardiac vegetation.

## Abstract

Staphylococcus aureus is a Gram-positive bacterium implicated in several infections. While the methicillin-resistant strains are usually a greater cause for concern, it is imperative to recognize that methicillin-sensitive Staphylococcus aureus (MSSA) is capable of causing a wide variety of complications as well. When disseminated MSSA is encountered, workup usually reveals a source for the septic emboli, be it infective endocarditis or septic thrombophlebitis. Here, we present a young gentleman who presented with a facial wound that grew MSSA, who, despite adequate source control, developed disseminated MSSA bacteremia with multiple lung abscesses. Most notably, there were no findings or septic thrombophlebitis, and both transthoracic echocardiogram (TTE) and transesophageal echocardiogram (TEE) revealed no cardiac vegetation.
