Expert Care for Pituitary Tumour

A pituitary tumour is an abnormal growth that develops in the pituitary gland, a small, pea-sized gland located at the base of the brain that controls the production of several essential hormones. The vast majority of pituitary tumours are benign (non-cancerous), though they can still cause significant health effects due to their impact on hormone levels and their location near important brain structures. At AIROC Hospitals, our neuro-endocrine specialists provide comprehensive diagnostic and treatment expertise to manage pituitary tumours effectively, whether functioning or non-functioning.

Because the pituitary gland regulates hormones that influence growth, metabolism, reproduction, and stress response, tumours affecting this gland can lead to a wide range of symptoms depending on which hormones are affected. At AIROC Hospitals, our team takes a comprehensive approach that addresses both the tumour itself and any related hormonal imbalances.

Types of Pituitary Tumour

Pituitary tumours are classified based on size and whether they produce excess hormones:

• Functioning (Hormone-Secreting) Tumours – Produce excess amounts of specific hormones, leading to distinct symptoms depending on the hormone involved:
• Prolactinoma – The most common type, producing excess prolactin.
• Growth Hormone-Secreting Tumours – Lead to conditions such as acromegaly in adults or gigantism in children.
• ACTH-Secreting Tumours – Cause excess cortisol production, leading to Cushing's disease.
• TSH-Secreting Tumours – A rarer type affecting thyroid hormone regulation.
• Non-Functioning Tumours – Do not produce excess hormones but can cause symptoms by pressing on surrounding structures as they grow.
• Microadenomas and Macroadenomas – Pituitary tumours are also classified by size, with microadenomas measuring less than 10 millimeters and macroadenomas measuring 10 millimeters or larger.
• Pituitary Carcinoma – An extremely rare malignant form that can spread beyond the pituitary gland, distinct from the far more common benign adenomas.

Identifying the specific type, size, and hormonal activity of a pituitary tumour is essential for guiding treatment, and our specialists at AIROC Hospitals ensure thorough evaluation for every patient.

Symptoms and Causes

Common Symptoms of Pituitary Tumour

Symptoms of a pituitary tumour depend on whether it is hormone-secreting and its size, and may include:

Hormone-related symptoms:

• Irregular or absent menstrual periods
• Unexpected breast milk production
• Changes in facial features, hand and foot size (acromegaly)
• Rapid weight gain, particularly around the abdomen and face (Cushing's disease)
• Fatigue and weakness
• Changes in sex drive or fertility

Symptoms related to tumour size or pressure:

• Headaches
• Vision problems, including loss of peripheral vision
• Nausea
• In rare cases, sudden severe headache and vision changes due to bleeding within the tumour (pituitary apoplexy), which requires urgent medical attention

Because symptoms can be subtle or develop gradually, persistent headaches, vision changes, or unexplained hormonal symptoms should be evaluated by a specialist.

Causes and Risk Factors

The exact cause of most pituitary tumours is not fully understood, but several factors are associated with increased risk:

• Genetic Syndromes: Conditions such as multiple endocrine neoplasia type 1 (MEN1) and familial isolated pituitary adenoma are linked to a higher risk of developing pituitary tumours.
• Family History: A family history of pituitary tumours or related genetic syndromes can increase individual risk.
• Age: Pituitary tumours can occur at any age but are most commonly diagnosed in adults between 30 and 60.
• Sex: Certain types, such as prolactinomas, are diagnosed more frequently in women, often related to associated symptoms affecting menstrual cycles.

Most pituitary tumours develop sporadically without a clear identifiable cause. Understanding relevant genetic and family history helps our team at AIROC Hospitals guide appropriate evaluation and counseling when relevant.

Diagnosis and Treatment

How Pituitary Tumour Is Diagnosed

At AIROC Hospitals, we use a comprehensive diagnostic approach to accurately identify and characterize pituitary tumours:

• Blood and Urine Tests: Measure hormone levels to determine whether the tumour is functioning and identify which hormones are affected.
• MRI of the Brain: The primary imaging test used to visualize the pituitary gland and detect tumours, even very small ones.
• CT Scan: May be used in certain situations, particularly when MRI is not suitable.
• Vision Testing: Assesses whether the tumour is affecting the optic nerves, which run close to the pituitary gland.
• Hormone Stimulation Tests: Specialized tests that help evaluate specific pituitary hormone function in more detail.

Treatment Options at AIROC Hospitals

Treatment for a pituitary tumour depends on its size, type, and hormonal activity, and may include:

• Watchful Monitoring: For small, non-functioning tumours without symptoms, regular monitoring with periodic imaging may be recommended instead of immediate treatment.
• Medication: Certain functioning tumours, particularly prolactinomas, often respond well to medications that can shrink the tumour and normalize hormone levels.
• Surgery: Often performed through minimally invasive approaches, such as through the nasal cavity, to remove tumours that are causing significant symptoms or hormonal imbalance.
• Radiation Therapy: Used for tumours that cannot be fully removed with surgery or that continue to grow, often using precisely targeted techniques to protect surrounding brain tissue.
• Hormone Replacement Therapy: May be needed after treatment if the pituitary gland's ability to produce certain hormones is affected.

Our multidisciplinary team at AIROC Hospitals — including neurosurgeons, endocrinologists, and radiation specialists — works together to design a treatment plan that addresses both the tumour and any related hormonal effects.

Prevention and Risk Factors

Because most pituitary tumours develop sporadically and their exact cause is not fully understood, there is currently no established way to prevent them directly. However, the following can support early detection:

• Genetic Counseling for Family History: Individuals with a family history of pituitary tumours or related genetic syndromes, such as MEN1, may benefit from genetic counseling and increased monitoring.
• Awareness of Hormonal Symptoms: Persistent changes in menstrual cycles, unexpected milk production, or changes in facial or body features should be evaluated promptly.
• Prompt Evaluation of Vision Changes or Headaches: Ongoing headaches or vision problems, particularly loss of peripheral vision, warrant timely medical assessment.
• Routine Follow-Up for Known Tumours: Individuals previously diagnosed with a pituitary tumour should maintain regular monitoring as recommended by their care team.

At AIROC Hospitals, we emphasize the importance of timely evaluation for persistent hormonal, vision, or headache symptoms, as early diagnosis plays a key role in successfully managing pituitary tumours and preserving long-term hormonal and visual health.
