Gallium SPECT/CT for permanent catheter infection

Area of Science:

• Nuclear Medicine
• Infectious Disease Imaging
• Medical Imaging

Background:

• Permanent catheters are crucial for hemodialysis in end-stage renal disease patients.
• Catheter-related infections pose a significant risk, complicating treatment and patient outcomes.
• Accurate and timely diagnosis of catheter infections is essential for effective management.

Observation:

• A 71-year-old female undergoing hemodialysis presented with symptoms of infection: fever, chills, and leukocytosis.
• Whole-body gallium scintigraphy revealed abnormal uptake in the right clavicular region.
• SPECT/CT imaging precisely localized the gallium uptake to the indwelling catheter in the right neck.

Findings:

• Gallium SPECT/CT demonstrated localized infection along the permanent catheter line.
• Coagulase-negative staphylococci were identified from cultures of the removed catheter.
• The imaging findings correlated with the microbiological results, confirming catheter-related infection.

Implications:

• Gallium SPECT/CT is a valuable tool for diagnosing permanent catheter infections.
• This imaging modality can precisely identify the site of infection, guiding targeted therapy.
• Early and accurate diagnosis improves patient management and potentially reduces complications associated with catheter-related bloodstream infections.
