title: An intrasellar cyst with both Rathke's cleft and epidermoid characteristics.
abstract: A case of an intrasellar cyst in a 48-year-old woman is reported. The cyst was lined by stratified squamous epithelium, most of which was covered by ciliated columnar epithelium. Most of the stratified squamous epithelium showed necrosis accompanied by signs of an acute inflammatory reaction. After surgical resection aseptic meningitis developed. The lumbar CSF findings were still abnormal four months after the operation.
