Abstract:
Pyomyositis has been uncommonly reported in temperature climates, but is being recognized with increasing frequency. The most common etiologic agent is Staphylococcus aureus, although other pathogens have been rarely implicated. The authors describe the first case of pyomyositis caused by Citrobacter freundii. Because of the rarity of this disease in North America, it is often initially misdiagnosed. Neuromuscular sonography, a non-invasive imaging technique, identified the muscle abscess in this patient.
Insights
Pyomyositis, a rare muscle infection, is increasingly seen in temperate regions. This report details the first case of pyomyositis caused by Citrobacter freundii, highlighting diagnostic challenges and the utility of neuromuscular sonography.
Area of Science:
- Infectious Diseases
- Medical Imaging
- Microbiology
Background:
- Pyomyositis, typically seen in tropical climates, is increasingly diagnosed in temperate regions.
- Staphylococcus aureus is the most common cause, but other pathogens are rarely implicated.
- Early diagnosis can be challenging due to its uncommon presentation.
Observation:
- This study reports the first documented case of pyomyositis caused by Citrobacter freundii.
- The patient presented with symptoms that initially led to misdiagnosis.
- Neuromuscular sonography was crucial in identifying the muscle abscess.
Findings:
- Citrobacter freundii is a rare but viable cause of pyomyositis.
- Neuromuscular sonography effectively visualized the muscle abscess, aiding diagnosis.
- The case underscores the importance of considering unusual pathogens in pyomyositis.
Implications:
- This finding expands the known spectrum of pathogens causing pyomyositis.
- Neuromuscular sonography should be considered in the diagnostic workup of suspected pyomyositis.
- Increased awareness of pyomyositis in non-tropical areas is warranted to improve patient outcomes.
