title: Duplication of the pituitary gland as shown by MR.
abstract: Duplication of the pituitary gland is a rare malformation. The authors describe a patient with features of the median cleft face syndrome (hypertelorism, V-shaped hairline, and developmental delay) who exhibited duplication of the pituitary gland and diffuse thickening of the hypothalamus (hypothalamic hamartoma) as shown by MR. The embryology of the developing pituitary gland and pathogenesis of pituitary duplication are discussed.
