Pituitary Adenomas
Make an AppointmentHow Pituitary Adenomas Are Diagnosed
Pituitary adenomas are noncancerous tumours that form in the pituitary gland, a small structure located at the base of the brain. This gland regulates vital body functions through hormone production, so any growth here can cause hormonal imbalances or pressure on nearby structures such as the optic nerves.
Diagnosis typically involves several steps:
- Comprehensive medical history and physical examination — focusing on symptoms such as headaches, vision changes, or unexplained fatigue.
- Hormone blood tests — to measure levels of cortisol, prolactin, growth hormone, and other pituitary hormones.
- Imaging scans (MRI or CT) — to confirm the presence, size, and position of the adenoma and its relation to nearby structures like the optic nerves.
- Visual field testing — to evaluate whether the tumour is affecting vision.
Accurate diagnosis is essential to determine whether the adenoma is functional (hormone-secreting) or non-functional, and to plan the most suitable treatment. Endocrinologists and neurosurgeons collaborate closely to ensure each patient receives a precise diagnosis and a tailored management plan.
Treatment Options for Pituitary Adenomas
Treatment for pituitary adenomas depends on the tumour’s size, hormone activity, and symptoms. The main treatment approaches include:
- Observation
For small, non-symptomatic adenomas, active surveillance may be recommended. This includes regular MRI scans and blood tests to monitor tumour growth and hormone levels. - Medication
Certain hormone-secreting adenomas, such as prolactinomas, can be effectively treated with medications that lower prolactin levels and shrink the tumour. - Surgery
Surgery is often needed for larger adenomas or those causing significant symptoms. The preferred surgical method is Endoscopic Endonasal Excision, a minimally invasive approach performed through the nasal passages. - Radiotherapy or Radiosurgery
Radiotherapy may be used when surgery isn’t possible or to treat residual tumour tissue after surgery. Modern precision techniques target only the tumour, minimising radiation exposure to nearby brain structures and hormone centres.
Preparing for Your Appointment
Before seeing your specialist, it helps to:
- Write down your symptoms, their duration, and how they affect your daily life.
- Bring any previous MRI or CT scan results and blood test reports.
- List all medications, supplements, and treatments you’re currently taking.
- Note any family history of hormonal or neurological conditions.
During your visit, the specialist will review your test results, and if needed, a neurosurgeon will discuss surgical options based on your tumour’s characteristics.
Post-Treatment Care
After treatment, our multidisciplinary team provides comprehensive follow-up care:
- Routine hormone testing to assess pituitary function.
- Follow-up MRI scans to monitor tumour stability.
- Vision assessments if the optic nerves were affected.
- Rehabilitation, nutritional, and psychological support to enhance overall recovery.
Recovery timelines vary, but most patients can return to normal activities within a few weeks, especially with minimally invasive procedures.
