Anti-N-methyl-D-aspartate receptor encephalitis associated with ovarian teratoma: Description of a case and anesthetic implications

N-methyl-D-aspartate receptor encephalitis is an autoimmune encephalitis reladonated or not with a neoplasm. Although its incidence is unknown, probably remains underdiagnosed. Epidemiological studies place it as the second cause of immune-mediated encephalitis and the first in patients aged Less of 30 years. It shows neuropsychiatric symptoms and autonomic instability. After diagnosis, based on the detection of antibodies in serum or cerebrospinal fluid, an occult malignancy must be investigated. While increasing number of cases have been diagnosed and the important role of this receptor in general anesthesia mechanisms, the interaction of the disease with anesthetic agents and perioperative stress is unknown. We describe the case of a patient with encephalitis associated to ovarian teratoma that underwent gynaecological laparoscopy.
