Ovarian teratoma and development of aquaporin-4-immunoglobulin G-seropositive neuromyelitis optica spectrum disorder

Takeaway

  • Ovarian teratoma may elicit paraneoplastic neuromyelitis optica spectrum disorder (NMOSD).

Why this matters ?

    Associations between certain malignancies and development of NMOSD have been recently reported, but the relationship between teratoma and NMOSD development is unclear. Results from this study indicate that patients with NMOSD should be screened for tumors, including teratomas, to improve patient outcomes.
