Abstract:
Staphylococcus aureus is endemic to human and animal skin and the gastrointestinal tract and is highly tissue-destructive. Staphylococcus aureus bacteremia has a high mortality rate of 20%-30%. A prostatic abscess is a rare complication of acute bacterial prostatitis. The focus of S. aureus infection is elsewhere in the body, and bacteremia causes the abscess, hence difficult to diagnose. Here, we report a case of prostatic abscesses, followed by a diagnosis of S. aureus bacteremia without specific physical findings. The patient was a 72-year-old male with independent activities of daily living who developed prostate and perifemoral abscesses with multiple vague symptoms due to diabetes-related methicillin-susceptible S. aureus bacteremia. It is important to comprehensively evaluate multiple vague symptoms considering the immunological conditions of patients and investigate any suspicion of bacteremia and abscess in deep parts of the body. General physicians should be system-specific specialists to deal with multiple symptoms among older immunocompromised patients.
Insights
Staphylococcus aureus bacteremia can lead to rare prostatic abscesses, even without typical symptoms. Early diagnosis requires evaluating vague symptoms in immunocompromised patients.
Area of Science:
- Infectious Diseases
- Internal Medicine
- Urology
Background:
- Staphylococcus aureus is a common pathogen causing tissue-destructive infections and bacteremia with high mortality.
- Prostatic abscesses are rare complications of acute bacterial prostatitis, often secondary to S. aureus bacteremia from a distant focus.
- Diagnosing S. aureus bacteremia presenting as a prostatic abscess can be challenging due to vague initial symptoms.
Observation:
- A case report of a 72-year-old male with diabetes presenting with prostate and perifemoral abscesses.
- The patient exhibited multiple vague symptoms, initially obscuring the underlying methicillin-susceptible S. aureus bacteremia.
- No specific physical findings pointed directly to the source of infection, complicating diagnosis.
Findings:
- Diagnosis of S. aureus bacteremia was established despite the absence of specific physical findings.
- The patient developed both prostatic and perifemoral abscesses secondary to the bacteremia.
- Methicillin-susceptible S. aureus was identified as the causative agent in this immunocompromised patient.
Implications:
- Comprehensive evaluation of vague symptoms is crucial, especially in immunocompromised individuals, to detect occult bacteremia and deep-seated abscesses.
- Physicians, particularly general practitioners, need to consider systemic infections and deep abscesses in older patients with multiple, non-specific complaints.
- Increased vigilance for S. aureus bacteremia and its rare complications like prostatic abscesses is warranted, even in the absence of classic signs.
