67Gallium uptake in psittacosis infection
Australian and New Zealand Journal of Medicine
|August 1, 1979
Summary
Gallium citrate isotope scanning detected focal uptake in the lungs of a patient with psittacosis, even without visible changes on X-ray. This imaging technique can reveal early signs of infection in the lungs.
Area of Science:
- Nuclear medicine
- Infectious disease imaging
- Radiopharmaceuticals
Background:
- Psittacosis is an infectious disease caused by Chlamydia psittaci.
- Pneumonitis and hepatitis are potential complications of psittacosis.
- 67Gallium citrate scanning is a nuclear medicine technique used to detect inflammation.
Observation:
- A febrile patient presented with symptoms of pneumonitis and hepatitis.
- Radiological examination did not reveal significant changes in the lungs.
- The liver showed only slight inflammatory cell infiltration.
Findings:
- Focal 67Gallium citrate uptake was observed in both lungs.
- No enhanced 67Gallium citrate concentration was noted in the liver.
- The patient was subsequently diagnosed with psittacosis.
Implications:
- 67Gallium citrate scanning can identify pulmonary inflammation in psittacosis before radiological changes are apparent.
- This imaging modality may aid in the early diagnosis of psittacosis.
- The findings highlight the utility of nuclear imaging in diagnosing atypical infections.
