Overview
The pituitary gland secretes hormones that regulate thyroid adrenal gonadal and growth functions under hypothalamic control. The anterior pituitary produces trophic hormones while the posterior pituitary stores vasopressin and oxytocin. Pituitary lesions affect multiple endocrine axes.
Pituitary Anatomy
The pituitary sits in the sella turcica connected to the hypothalamus by the pituitary stalk. Microadenomas and macroadenomas alter hormone secretion and compress adjacent structures. MRI is the modality of choice for pituitary imaging.
Hormonal Disorders
Pituitary adenomas cause hypersecretion syndromes such as acromegaly Cushing disease and prolactinoma or hypopituitarism from mass effect. Dynamic endocrine testing and imaging guide diagnosis and treatment. Surgical and medical therapies restore hormonal balance.
Clinical Relevance
Pituitary disease impacts growth metabolism reproduction and stress response. Multidisciplinary endocrine and neurosurgical care optimizes outcomes. Long term monitoring addresses recurrence and hormonal replacement needs.
