Background: Recently, paraneoplastic encephalitis associated with ovarian teratoma has been described and related to an autoantibody.
Methods: We describe four patients with ovarian teratoma-associated encephalitis (OTE) and compared their clinical pictures with those of 17 previously reported patients with OTE.
Results: Clinically, OTE was characterized by the development of acute prominent psychiatric symptoms (20 of 21 patients), seizures (15 of 21 patients), and central hypoventilation (13 of 21 patients).
