Some Effects of Transection of the Pituitary Stalk.

Missing Pituitary Stalk: A Key to the Diagnosis

Growth after Hypophyseal Stalk Transection and Hypophysectomy in Beef Calves

Growth hormone (GH) is a metabolic hormone that plays an important role in long-bone growth and muscle accretion in mammals. The anterior pituitary gland at the base of the brain is the primary site of GH production and release into the general circulation. Neurons in the arcuate nucleus of the hypothalamus in the lower part of the brain secrete GH-releasing hormone ([GHRH] or factor [GRF]) and...

Successful Pregnancies and Deliveries in a Patient With Evolving Hypopituitarism due to Pituitary Stalk Transection Syndrome: Role of Growth Hormone Replacement

We herein report a 31-year-old Japanese woman with evolving hypopituitarism due to pituitary stalk transection syndrome. She had a history of short stature treated with growth hormone (GH) in childhood and had hypothyroidism and primary amenorrhea at 20 years old. Levothyroxine replacement and recombinant follicle stimulating hormone-human chorionic gonadotropin (FSH-hCG) therapy for ovulation ...

بررسی وجود انحراف طرفی ساقه غده هیپوفیز نرمال در افراد بالغ توسط MRI

    Background & Aim: Magnetic resonance imaging(MRI) in the coronal plane before and after contrast is currently considered to be the most specific and sensitive technique for imaging pituitary gland. However, because of the false negative results of this method in the detection of pituitary microadenomas and the importance of finding these microadenomas, infundibular deviation or tilt in MRI ...

Ectopic Posterior Pituitary in Macroadenomas: Demonstration by Dynamic MR Imaging

Introduction The ectopic posterior pituitary is an aberrant accumulation of neurosecretory materials at the median eminence or infundibular stem resulting in functional preservation of hormonal production and release, which is often seen in patients with transection of the pituitary stalk (1). W can also be developed due to compression to the hypothalamohypophsial tract by alarge macroadenoma (...
