Gram-Negative Bacteremia With Atypical Neurologic Presentation Following Tattoo Application.

Tattoo-related infections are typically caused by gram-positive bacteria like Staphylococcus aureus and present with localized symptoms. However, this case describes a 48-year-old diabetic woman who developed Escherichia coli bacteremia without any visible signs of infection at the tattoo site. She presented with systemic symptoms including fever, chills, and weakness, initially raising concerns for a neurological event. Laboratory tests confirmed gram-negative bacteremia, and the tattoo was identified as the likely source. The absence of local manifestations and the rare involvement of E. coli highlight the need for clinicians to consider systemic infections as a potential complication of tattooing, especially in high-risk patients. Early recognition and appropriate antibiotic therapy resulted in the patient's full recovery. This case underscores the importance of infection control during tattooing and vigilance for atypical presentations.
