    Area of Science:

    • Neurosurgery
    • Pathology
    • Oncology

    Background:

    • Paraganglioma is a rare neuroendocrine tumor that can occur in the cauda equina region.
    • Understanding the ultrastructure of these tumors is crucial for diagnosis and treatment.

    Observation:

    • New ultrastructural details were observed in a cauda equina paraganglioma.
    • Specific observations included nerve fibers within the tumor capsule.
    • Tumor cells exhibited clear vesicles and tubulo-vesicular structures in cytoplasmic processes.

    Findings:

    • Fenestrated endothelial cells were identified within the tumor vasculature.
    • Numerous tubular bodies were noted in some endothelial cells.
    • These findings provide novel insights into the cellular composition of cauda equina paraganglioma.
