Abstract:
Radiographic examination of a pig-tailed macaque (Macaca nemestrina) with pneumonia revealed a large pneumatocele. The pneumatocele, a thin-walled, partially fluid filled radiolucent area, occupied approximately one-third of the left thorax. Rapid resolution of the pneumatocele accompanied antimicrobial treatment of the pneumonia and coincided with clinical improvement. Severe pulmonary acariasis was found at postmortem 15 months later.
Insights
A pig-tailed macaque with pneumonia developed a large pneumatocele that resolved with antimicrobial treatment. Postmortem examination revealed severe pulmonary acariasis, suggesting a potential link.
Area of Science:
- Veterinary Radiology
- Primate Pathology
- Pulmonary Medicine
Background:
- Pneumatocele is a rare pulmonary finding, particularly in non-human primates.
- Understanding the etiology and resolution of pneumatocele is crucial for diagnosing and managing respiratory diseases in macaques.
Observation:
- Radiographic examination of a pig-tailed macaque (Macaca nemestrina) identified a large pneumatocele occupying a significant portion of the left thorax.
- The pneumatocele presented as a thin-walled, partially fluid-filled radiolucent area.
Findings:
- The pneumatocele showed rapid resolution concurrently with antimicrobial treatment for pneumonia.
- Clinical improvement in the macaque was observed alongside the pneumatocele's resolution.
- Postmortem examination 15 months later revealed severe pulmonary acariasis.
Implications:
- This case highlights the potential for pneumatocele resolution with appropriate pneumonia treatment in macaques.
- The findings suggest a possible association between pulmonary acariasis and pneumatocele development or exacerbation.
- Further research is warranted to explore the pathogenesis of pneumatocele in the context of parasitic lung infections in primates.
