(MRI) a type of radiography scan used to visualise parts of the body internally for diagnostic purposes. Electromagnetic energy is used to create an image.

Empty sella syndrome
Empty sella syndrome is the term used to describe the appearance of a small, shrunken or absent pituitary gland on pituitary imaging. Most patients have no symptoms, and generally no treatment is required. If hormone deficiencies are present, hormone replacement therapy should be considered.

ultrasound scan

Pineal gland
The pineal gland is situated in the middle of the human brain and is the major site of the body's melatonin production.

Gonadotrophin-releasing hormone
Gonadotrophin-releasing hormone is released from the hypothalamus in the brain. It controls the production of luteinising hormone and follicle stimulating hormone from the pituitary gland.

TSH-secreting pituitary adenoma
TSH-secreting pituitary adenomas are slow-growing benign pituitary tumours that produce thyroid stimulating hormone (TSH) and are a very rare cause of hyperthyroidism (overactive thyroid).

Somatostatinomas are rare neuroendocrine tumours that arise from tumour cells originated from specialised hormone-producing cells in the endocrine pancreas and duodenum (first part of small intestine).

Endometriosis is a condition in women where the lining of the womb grows outside of the womb causing scar tissue and painful monthly periods.

Sheehan's syndrome is a rare condition affecting the pituitary gland that occurs as a result of heavy bleeding during or after childbirth.

Craniopharyngiomas are rare, slow-growing benign brain tumours which most commonly occur above the pituitary gland, but occasionally are found within the bony cup containing the pituitary gland.

Amenorrhoea is the term used to describe a lack of 'periods' (menstrual cycles) in women. The management of amenorrhoea depends on the underlying cause.

A paraganglioma is a rare type of tumour that forms along major blood vessels and nerves. Paragangliomas can occur in the head, neck, chest or abdomen.

Gastrinomas are neuroendocrine tumours that are usually found in the first part of the small intestine or in the pancreas, which produce excess amounts of the hormone called gastrin.

A phaeochromocytoma is a tumour of the adrenal gland that produces excess amounts of hormones such as adrenaline and noradrenaline.

Familial medullary thyroid cancer
Familial medullary thyroid cancer is a rare inherited form of thyroid cancer.

Gigantism is a rare condition due to abnormal, accelerated growth caused by excessive amounts of growth hormone secretion during childhood or adolescence. It is almost always the result of a growth hormone-secreting pituitary tumour.

Hypopituitarism is the failure of production of one or more hormones from the pituitary gland.

Precocious puberty
Precocious puberty is the abnormally early development of any secondary sexual characteristics: before the age of nine years in a boy and eight years of age in a girl.

Patient factsheet: UK guidance on differences/disorders of sex development in children
This is a patient factsheet on the Society for Endocrinology's guidance document on the initial evaluation of a child with a suspected differences/disorders of sex development.

Pituitary apoplexy
Pituitary apoplexy is a medical emergency. It is caused by either a bleed into and/or death of an area of tissue in the pituitary gland. It is usually associated with the presence of a pituitary tumour.

Thyroid eye disease
Thyroid eye disease is an autoimmune condition that affects the eyes causing swelling, inflammation and sometimes visual problems.

An insulinoma is a type of tumour that occurs in the pancreas. The tumour secretes too much insulin, which causes blood glucose (sugar) to drop to low levels.

Delayed puberty
Delayed puberty is defined as no secondary sexual maturation or any sign of puberty by the age of 13 years in girls and 14 years in boys.

A glucagonoma is a very rare tumour of the pancreas in which there is an increase in release of the hormone glucagon, causing a characteristic skin rash and raised blood sugar levels.

Resistance to thyroid hormone
Resistance to thyroid hormone is a rare genetic condition where some body tissues do not respond normally to thyroid hormones produced by the thyroid gland. It may be associated with no symptoms or with features of both an overactive and underactive thyroid.

Non-functioning pancreatic NETs
Non-functioning pancreatic neuroendocrine tumours (NETs) are tumours that originate in specialised cells of the pancreas.

Acromegaly is a condition that develops due to overproduction of growth hormone, usually caused by a benign tumour of the pituitary gland. It leads to an increase in size of the hands and feet, a change in the appearance of the face and enlargement of the internal organs.

Non-functioning pituitary tumours
Non-functioning pituitary tumours are the most common benign growths in the pituitary gland. These tumours are usually identified because of impaired vision or hormone deficiencies.

Cushing's disease
Cushing's disease is the condition resulting from a pituitary tumour secreting excess amounts of adrenocorticotropic hormone (ACTH), which then stimulates the adrenal glands to release excess amounts of the hormone cortisol.

Multiple endocrine neoplasia type 1
Multiple endocrine neoplasia type 1 is a rare inherited disease, which can result in tumours in the pituitary and parathyroid glands, and pancreas.

Endometrial cancer
Endometrial cancer is a form of cancer that originates from the tissue that lines the womb. This tissue is called the endometrium.

Cushing's syndrome
Cushing's syndrome is the name given to the collection of signs and symptoms that occur when the body is exposed to too much of the hormone cortisol.

Multiple endocrine neoplasia type 2B
Multiple endocrine neoplasia type 2B (MEN2B) is a rare inherited disease causing the development of tumours in the thyroid, adrenal and parathyroid glands, and mucosal tumours.

Multiple endocrine neoplasia type 2A
Multiple endocrine neoplasia type 2A (MEN2A) is a rare inherited disease causing the development of tumours in the thyroid, adrenal and parathyroid glands.

Primary hyperaldosteronism
Primary hyperaldosteronism refers to a condition in which one or both adrenal glands generate too much of a hormone called aldosterone. This causes sodium (salt) retention, leading to high blood pressure.
