Rathke's cleft cyst presenting with recurrent aseptic meningitis and inflammatory apoplexy: illustrative case.

Recurrent aseptic meningitis with apoplexy-like symptoms is a rare presentation of RCC. The authors propose the term inflammatory apoplexy to describe such a presentation without evidence of abscess, necrosis, or hemorrhage. The mechanism is unclear although may be due to intermittent microleakage of cyst contents into the subarachnoid space.
