    A rare invasive paraganglioma in the posterior mediastinum led to spinal cord compression in a young woman. Electron microscopy revealed characteristic dense-cored granules, highlighting an unusual cause of neurological compromise.

    Area of Science:

    • Neuro-oncology
    • Pathology
    • Spinal Surgery

    Background:

    • Paragangliomas are rare neuroendocrine tumors arising from neural crest cells.
    • Posterior mediastinal paragangliomas are uncommon, and their invasive potential requires careful consideration.
    • Spinal cord compression is a serious neurological emergency often caused by tumors or other masses.

    Observation:

    • A 31-year-old woman presented with symptoms of spinal cord compression.
    • Imaging revealed an invasive paraganglioma in the posterior mediastinum.
    • The tumor extended into the epidural space, directly compressing the spinal cord.

    Findings:

    • Electron microscopy of the paraganglioma demonstrated numerous dense-cored granules within the tumor cell cytoplasm.
    • These ultrastructural findings are characteristic of paraganglioma.

  • The invasive nature of this mediastinal paraganglioma was confirmed by its extension into the epidural space.

    • Implications:

    • This case highlights an unusual etiology for spinal cord compression.
    • Understanding the ultrastructure of mediastinal paragangliomas is crucial for diagnosis and management.
    • Early recognition and surgical intervention are vital for patients with spinal cord compression due to invasive tumors.
