Villonodular synovitis in the spinal canal: case report

G M Kleinman, T F Dagi, C E Poletti

    Journal of Neurosurgery
    |June 1, 1980
    PubMed
    Summary

    Villonodular synovitis, typically affecting synovial tissues, was identified as an extremely rare cervical epidural mass in a 65-year-old woman. This finding highlights the importance of considering rare diagnoses in spinal oncology.

    Area of Science:

    • Neuropathology
    • Spinal Oncology
    • Histopathology

    Background:

    • Villonodular synovitis is characterized as an inflammatory and proliferative condition affecting synovial tissues.
    • The typical presentation involves joints, making extra-articular occurrences exceptionally rare.

    Observation:

    • A case study details a 65-year-old female patient presenting with a cervical epidural mass.
    • Histological examination confirmed the mass to be villonodular synovitis.

    Findings:

    • This represents an extremely rare instance of villonodular synovitis occurring in the cervical epidural space.
    • The lesion's cellularity and presence of multinucleated giant cells can mimic other neoplastic processes.

    Implications:

    • Accurate histological diagnosis is crucial to differentiate villonodular synovitis from metastatic malignancies or giant-cell tumors of bone.
    • This case expands the known anatomical distribution of villonodular synovitis, emphasizing the need for broad differential diagnoses in spinal lesions.
