Mediastinal actinomycosis is a rare condition in children that can mimic lymphoma, complicating diagnosis and treatment. The use of advanced diagnostic techniques like mNGS can provide essential insights when traditional methods fail.
Data Highlights
No numerical data or trial data presented in the article.
Key Findings
Mediastinal actinomycosis can present as a mass-like lesion in children, mimicking lymphoma.
Initial imaging showed multiple enlarged mediastinal lymph nodes with features overlapping those of malignancy.
Metagenomic next-generation sequencing identified Actinomyces oris in the biopsy, confirming the diagnosis.
Postoperative pathology revealed granulomatous inflammation with caseous necrosis, further supporting the diagnosis of actinomycosis.
Antimicrobial therapy led to improvement, but imaging showed little change in lesions, necessitating surgical intervention.
Follow-up imaging demonstrated reduction of the residual lesion, and the patient remained asymptomatic.
Clinical Implications
Clinicians should consider actinomycosis in the differential diagnosis of mediastinal masses in children, especially when imaging suggests malignancy. The integration of mNGS can aid in accurate diagnosis and prevent mismanagement.
Conclusion
This case underscores the importance of advanced diagnostic techniques in distinguishing between actinomycosis and lymphoma in pediatric patients. Early and accurate diagnosis can lead to appropriate treatment and improved outcomes.
