Status epilepticus and anti-NMDA receptor encephalitis after resection of an ovarian teratoma

Anti-N-methyl-D-aspartate receptor encephalitis is a recently recognised autoimmune, paraneoplastic syndrome that typically presents with psychiatric disturbance, reduced conscious level and seizures. The disorder has been previously associated with ovarian teratomas. We present the case of a 35-year-old female, with a previous surgical history for resection of an ovarian teratoma, who later developed status epilepticus and anti-N-methyl-D-aspartate receptor encephalitis requiring intensive care management. Her presentation, treatment and early follow-up are described, alongside an overview of anti-N-methyl-D-aspartate receptor encephalitis pathophysiology and intensive care management.
