    Summary

    This case report details osteosarcoma manifesting as calcific mediastinal lymphadenopathy. The tumor caused significant swallowing and breathing difficulties, confirmed by imaging and isotope uptake.

    Area of Science:

    • Oncology
    • Radiology
    • Pathology

    Background:

    • Osteosarcoma is a primary bone malignancy typically affecting long bones.
    • Mediastinal lymphadenopathy can occur in various conditions, but calcific presentation is rare.

    Observation:

    • A patient presented with progressive dysphagia and bronchial erosion.
    • Imaging revealed calcific mediastinal lymphadenopathy.
    • The lesion demonstrated increased isotope uptake on bone scintigraphy.

    Findings:

    • The mediastinal lesion was confirmed to be osteosarcoma.
    • The tumor exhibited growth on serial computed tomography (CT) scans.
    • The calcific nature of the lymphadenopathy was a key diagnostic feature.

    Implications:

    • This case highlights an unusual presentation of extraskeletal osteosarcoma.
    • It underscores the importance of considering rare diagnoses in complex mediastinal masses.
    • Advanced imaging modalities are crucial for characterizing such lesions.
