Imaging findings
The chest radiograph shows a large lesion in the right upper hemithorax without evidence of rib splaying, displacement, or destruction. CT confirms a large mass occupying the majority of the right upper chest. MRI T2 sequences demonstrate no involvement with the neural foramen. Pathological examination confirmed a paraganglioma, originating from the paraspinal sympathetic chain within the posterior mediastinum.
Key takeaways
Paragangliomas can manifest as large posterior mediastinal masses in pediatric patients. Imaging, particularly MRI, is valuable for assessing the extent of the mass and its relationship to neural structures. These tumors can arise from the paraspinal sympathetic chain.
