Pituitary amenorrhea

1- Sheehan syndrome;
– Ischemic necrosis of anterior pituitary after spasm in its arterioles.
– Caused by severe hemorrhage and shock (usually postpartum).
– Manifestations:
* Impaired pituitary functions;
– Lactogenic → Failure of lactation (1st presentation),
– Gonadotrophic → amenorrhea, genital atrophy,
– Thyrotrophic, corticotrophic and somatotrophic.
* Hypothyroidism → bradycardia, intolerance to cold, constipation.
* Adrenocortical failure → No axillary sweating,
Loss of axillary and pubic hair,
Decrease skin pigmentation.
Hypotension and loss of weight.
♦ Simmond’s disease:
– Loss of all anterior pituitary function,
– Due to any cause (Not only postpartum haemorrhage),
– In either sex (Not only in female).
– Treatment: HRT:
* Cortisone and thyroxin for life (ACTH and TSH may be tried).
* HMG (Contain FSH and LH) for induction of ovulation.

2- Frohlich’s syndrome:
* It is hypothalamo- pituitary disorder, so discussed with both.
3- Empty sella syndrome;
– Defect in Diaphragm sella → cerebrospinal fluid and pia herniates into the pituitary fossa
producing → compression atrophy of the pituitary gland.
– The result is hypopituitarism with amenorrhea (↓↓ gonadotropins) and galactorrhea?!! (↓PIF)
– This is documented by CT scan and air encephalogram.
– Treatment: Hormone replacement therapy.
4- Pituitary infantilism “Levi-Lorain syndrome”:
– 1ry amenorrhea.
– Low level of growth hormone and gonadotropins,
– Arrest of growth and hypogonadism (infantilism).
5- Lawrence Moon Biedle syndrome:
– As Frohlich’s syndrome, plus
– Limb anomalies e.g. Polydactyly or syndactyly,
– Mental retardation, &
– Blindness (retinitis pigmentosa).
6- Pituitary adenomas;
* Prolactin producing adenoma;
– Tumor arising from PRL secreting cells.
– One of amenorrhea- galactorrhea syndromes.
– Micro-adenoma is < 10 mm diagnosed only by MRI or CT.
– Macro-adenoma is > 10 mm may cause optic atrophy.
* Chromophobe adenoma;
– Tumor arising from Chromophobe cells.
– Pressure atrophy of hormone producing cells.
– Amenorrhea, optic atrophy and distorted sella turcica on X-ray,
*Forbes syndrome: (rare);
– Prolactin producing chromophobe adenoma.
– Amenorrhea- galactorrhea manifested.
– A small sized uterus without history of pregnancy.
* Acidophil adenoma;
– Tumor arising from GH secreting cells.
– Excessive growth hormone manifestations (gigantism or acromegaly).
– Amenorrhea results from destructed gonadotrophes.
* Basophil adenoma;
– Tumor arising from ACTH secreting cells.
– Excessive ACTH production (Cushing syndrome);
– Trunkal obesity, mild hirsutism,
– Tendency to diabetes and hypertension.
– Amenorrhea results from destructed gonadotrophes.
* Treatment of pituitary adenomas:
– Prolactin secreting adenoma:
a- Medical treatment e.g. Bromocriptine.
b- Surgical removal if drug resistant or causing field changes.
