Gallium-67 SPECT/CT Detection of Lower Extremity Muscle Abscess in Vibrio vulnificus Infection.

Area of Science:

• Infectious Diseases
• Medical Imaging
• Nephrology

Background:

• Vibrio vulnificus infections are severe, particularly in immunocompromised individuals.
• Patients with chronic renal failure and liver cirrhosis are at high risk.
• Early diagnosis of deep soft-tissue infections is crucial for effective treatment.

Purpose of the Study:

• To report a case of Vibrio vulnificus bacteremia with deep soft-tissue infection.
• To evaluate the utility of gallium-67 SPECT/CT in diagnosing intramuscular abscesses.
• To emphasize the importance of timely intervention in high-risk patients.

Main Methods:

• A 65-year-old male on hemodialysis presented with symptoms after consuming raw seafood.
• Initial CT showed no inflammation; gallium-67 SPECT/CT was performed due to persistent symptoms.
• Ultrasound-guided percutaneous drainage and antibiotic therapy were administered.

Main Results:

• Gallium-67 SPECT/CT revealed multiple intramuscular abscesses, especially in the gastrocnemius muscles.
• Follow-up CT confirmed abscess formation.
• The patient showed gradual clinical improvement after drainage and antibiotics.

Conclusions:

• Gallium-67 SPECT/CT is a valuable tool for detecting deep soft-tissue infections.
• Early diagnosis and intervention improve outcomes in Vibrio vulnificus infections.
• This imaging modality aids in managing severe infections in high-risk patients.
