Case 26-2008

A 26-year-old woman was admitted to this hospital because of headache, behavioral changes, abnormal movements, and inability to communicate. Seven weeks before admission, headaches developed, followed by somnolence, mood alteration, confusion, memory loss, incoherent speech, and involuntary movements. An evaluation for infection was negative. Imaging studies showed a normal brain and an ovarian mass consistent with a dermoid cyst. A diagnostic procedure was performed.
