Quick Answer
Pituitary tumors cause hormonal imbalances, vision problems and headaches — usually benign but need specialist evaluation and treatment.

Pituitary tumors are growths in the pituitary gland — a pea-sized gland at the base of the brain that produces hormones regulating growth, metabolism, reproduction and stress response. Most pituitary tumors are benign (non-cancerous) and slow-growing, but even small tumors can cause significant symptoms through hormone overproduction or compression of surrounding structures.
Types and symptoms
Functioning tumors (produce excess hormones): prolactinoma (galactorrhea, infertility, decreased libido), acromegaly (enlarged hands/feet, facial features), Cushing's disease (weight gain, moon face, hypertension), TSH-secreting (hyperthyroidism). Non-functioning tumors: mass effect — headache, vision problems (bitemporal hemianopia from optic chiasm compression), hypopituitarism (hormone deficiencies).
Diagnosis
MRI of brain with pituitary focus shows the tumor. Hormone panel (prolactin, IGF-1, cortisol, TSH, LH/FSH, testosterone/estradiol) identifies overproduction or deficiency. Visual field testing detects chiasmal compression.
Treatment
Medication: dopamine agonists for prolactinoma (first-line — shrinks tumor). Surgery: transsphenoidal approach (through nose/sphenoid sinus) — removes tumor, preserves pituitary function when possible. Radiation therapy: for residual/recurrent tumors or those unsuitable for surgery. Hormone replacement for hypopituitarism. Most pituitary tumors are curable or controllable.
When to seek professional evaluation
Pituitary tumors cause diverse symptoms — hormonal changes, vision problems, headaches — requiring endocrinology and neurology collaboration.

Migraine is a neurological condition; headache is one feature. Associated symptoms and functional impact are important for diagnosis.
Aura refers to visual, sensory, or speech symptoms that precede the headache in some people. Both types are migraine; the presence of aura may influence management discussion.
