Pituitary tumors affect hormones, vision or both
Most pituitary tumors are not cancer, but they can secrete excess hormones or compress the optic pathways and normal pituitary gland.
Endoscopic transsphenoidal surgery reaches many tumors through the nasal corridor. Prolactin-secreting tumors often respond to medicine, while other functional or compressive tumors may need surgery.
Adrenal insufficiency, severe electrolyte disturbance or acute visual loss requires urgent coordinated endocrine and neurosurgical care.
Who may be considered?
Specialist review may help when the diagnosis, symptoms and previous treatment create a focused question about pituitary tumor surgery.
- Visual field loss or optic compression.
- Cushing disease, acromegaly or another functional tumor needing surgical control.
- A nonfunctioning macroadenoma causing symptoms or growth.
- Residual or recurrent tumor after prior treatment.
What the specialist team must confirm
The team reviews pituitary-protocol MRI, visual fields, complete pituitary hormone testing, symptoms of hormone excess or deficiency, previous medicines, sinus anatomy, vascular relationship and prior surgery or radiation.
Key points for this treatment

From hormone phenotype to targeted skull-base surgery
The team defines whether the goal is biochemical remission, decompression, tissue diagnosis or control of growth.
Hormone and fluid monitoring begins immediately
After surgery, sodium, urine output, cortisol and other pituitary functions are watched closely. Nasal and cerebrospinal-fluid leak precautions are explained.
Later review includes pathology, MRI, visual fields and hormone testing. Some deficits recover; others require long-term replacement.

Risks, limits and realistic expectations
Risks include bleeding, infection, cerebrospinal-fluid leak, meningitis, vascular injury, visual loss, diabetes insipidus, low sodium, loss of pituitary function, residual tumor and death.
Sudden severe headache with visual loss, collapse, confusion, fever, clear nasal fluid or extreme thirst and urination requires urgent local care.
