Falsely normal radionuclide scans for osteomyelitis
American Journal of Diseases of Children (1960)
|May 1, 1980
Abstract:
Three children are described with osteomyelitis confirmed by roentgenogram, blood culture, bone culture, and/or histologic findings. None had an abnormal technetium scintigram. Despite the lack of falsely normal bone scans for osteomyelitis reported in the literature, our cases demonstrate the importance of instituting antibiotic therapy on the basis of clinical suspicion since no single nonsurgical procedure can be relied on to make a diagnosis of osteomyelitis.
Insights
Technetium scintigrams can appear normal in children with osteomyelitis. Early antibiotic treatment based on clinical suspicion is crucial for diagnosis, as imaging alone may be unreliable.
Area of Science:
- Pediatric Infectious Diseases
- Medical Imaging
- Skeletal System Infections
Background:
- Osteomyelitis diagnosis in children often relies on a combination of clinical presentation and diagnostic imaging.
- Technetium scintigraphy is a common imaging modality used to detect bone infections.
Observation:
- Three pediatric cases of osteomyelitis are presented.
- All three patients had confirmed osteomyelitis via roentgenogram, blood culture, bone culture, and/or histologic findings.
- None of the patients exhibited abnormal technetium scintigrams.
Findings:
- This study highlights instances where technetium scintigraphy yielded falsely negative results for osteomyelitis.
- The findings challenge the universal reliability of bone scans in diagnosing pediatric osteomyelitis.
- Despite literature suggesting otherwise, these cases show normal bone scans can occur in confirmed osteomyelitis.
Implications:
- Clinical suspicion remains paramount in diagnosing pediatric osteomyelitis, even with non-diagnostic imaging.
- Antibiotic therapy should be initiated promptly based on clinical judgment when osteomyelitis is suspected.
- Reliance on a single non-surgical diagnostic procedure, such as technetium scintigraphy, is not advisable for confirming osteomyelitis.
