A condition associated with underdevelopment or absence of the diaphragma sellae which allows herniation of the meninges into the SELLA TURCICA. The pituitary gland becomes compressed against the walls of the sella and the sella may enlarge. Female gender; OBESITY; PSEUDOTUMOR CEREBRI; and pituitary ADENOMA are associated with this condition, which may present with HEADACHE. (From Joynt, Clinical Neurology, 1992, Ch36, p85)
