Abstract:
Mycoplasma pneumonia, an atypical pneumonia that commonly causes community-acquired pneumonia, can induce extrapulmonary manifestations at different sites, such as the central nervous system, skin, and gastrointestinal tract. These extrapulmonary manifestations can present without respiratory symptoms, making the diagnosis challenging. Herein, we report the case of a 26-year-old woman who presented with polyarthritis following fever and gastrointestinal symptoms. At the time of examination, mycoplasma pneumonia had spread in the community, which led to the diagnosis. Her polyarthritis improved one week after the administration of an antibiotic and a non-steroidal anti-inflammatory drug. Understanding the prevalence of infectious diseases in the community can help in the diagnosis of uncommon presentations based on symptoms, such as the acute onset of polyarthritis, that may be caused by an infectious disease.
Insights
Mycoplasma pneumonia can cause joint inflammation without typical respiratory symptoms. Early diagnosis, considering community infection prevalence, aids treatment of these unusual presentations.
Area of Science:
- Infectious Diseases
- Rheumatology
- Pulmonology
Background:
- Mycoplasma pneumoniae is a common cause of community-acquired pneumonia.
- It can lead to extrapulmonary manifestations affecting various organ systems, including joints.
- Diagnosis can be difficult when respiratory symptoms are absent.
