description | Pituitary stalk interruption syndrome presenting as primary amenorrhea. The pituitary stalk interruption syndrome is a rare congenital defect that is characterized by the absence or thinning of the pituitary stalk, an absent or ectopic posterior pituitary lobe, and hypoplasia or aplasia of the anterior lobe. The clinical presentation is variable. It is usually diagnosed in the neonatal period due to the clinical manifestations that arise as a consequence of hormonal deficiencies. However some patients are diagnosed at a latter stage in life. Growth hormone deficiency it is observed in virtually all patients and can be associated to other anterior pituitary hormonal deficiencies. There is a high frequency of associated extra-pituitary malformations including those involving the central nervous system and the craniofacial structures. We report the case of a 19-year-old woman with primary amenorrhea, lack of secondary sexual characteristics, short stature, low body mass index due to hypergonadotropic hypogonadism and growth hormone deficiency. The remaining pituitary hormones were normal. A pelvic ultrasound revealed orthotopic ovaries and uterus that were decreased in size. Her karyotype was normal. An MRI of the sellar region revealed an ectopic posterior pituitary lobe, and anterior pituitary hypoplasia with a thin pituitary stalk. The patient was treated with estradiol valerate and norgestrel as well as with growth hormone. In conclusion, the pituitary stalk interruption syndrome is a rare form of congenital hypopituitarism that should be considered in cases of growth hormone deficiency and primary amenorrhea particularly in the presence of extra pituitary malformations involving the central nervous system. |
