What are the common symptoms of a pituitary tumor? A pituitary tumor is a neoplastic disease that occurs in the pituitary gland. The pituitary gland is located at the base of the brain and is responsible for producing and secreting multiple hormones that regulate many vital functions of the body. The common symptoms of pituitary tumors are diverse, and their specific manifestations vary depending on individual differences and tumor characteristics. Below are some frequent symptoms and their possible causes:   

Common symptoms of a pituitary tumor: 

1. Visual problems – Due to compression of the optic nerve or optic chiasm by the tumor, patients may experience decreased vision, visual field defects (such as bitemporal hemianopsia), and in severe cases, blindness in one or both eyes.   

2. Headache – Approximately one‑third to two‑thirds of patients with pituitary tumors experience headaches, usually caused by the tumor pressing on surrounding structures.   

3. Endocrine and metabolic abnormalities:  

   - Sexual dysfunction – Reduced libido, menstrual irregularities, infertility, and diminished male sexual function.  

   - Acromegaly – Enlargement of bones and soft tissues due to excessive growth hormone secretion.  

   - Cushing's syndrome – Obesity, rounded face, hypertension, and impaired glucose tolerance resulting from excessive adrenocorticotropic hormone (ACTH) secretion.  

   - Galactorrhea – Spontaneous milk secretion in non‑lactating women.  

   - Other endocrine symptoms, such as hyperthyroidism or hypothyroidism, and diabetes insipidus.   

4. Compressive symptoms – When the tumor compresses the cavernous sinus, hypothalamus, or other structures, patients may present with diplopia, loss of smell, and autonomic nervous system dysfunction.   

The appearance of these symptoms is mainly due to abnormal hormone secretion caused by the pituitary tumor and the compression of surrounding tissues by the tumor. To alleviate these symptoms, treatment targeting the pituitary tumor is necessary. Common treatment methods include:   

1. Surgery – For some pituitary tumors, surgical resection is the preferred treatment, especially when medication is ineffective or the tumor is large. Tumors can be removed via transsphenoidal microsurgery or transcranial surgery to relieve compression on surrounding tissues and restore normal endocrine function as much as possible.   

2. Medication – Corresponding drugs are used for different types of pituitary tumors. Drug therapy is generally used to relieve symptoms but does not cure the tumor fundamentally and may require lifelong administration.   

3. Radiotherapy – For patients who are not suitable for surgery or who have residual tumor after surgery, radiotherapy such as Gamma Knife or stereotactic radiosurgery can be employed. Stereotactic radiotherapy precisely targets the tumor while minimizing damage to surrounding normal brain tissue.   

4. Supportive care – This includes pain management, anti‑epileptic treatment, nutritional support, physical therapy, and psychosocial support to improve quality of life.   

The goals of treatment are to remove the tumor, relieve compressive symptoms, restore endocrine balance, and thereby improve or eliminate the various clinical symptoms caused by the pituitary tumor. During treatment, patients should be closely monitored for changes in their condition, and regular endocrine function assessments and imaging follow‑ups should be performed.   

It is important to note that the treatment of pituitary tumors requires comprehensive consideration of the patient's specific circumstances, such as age, tumor size, and symptom severity, to develop an individualized treatment plan. Therefore, patients are advised to seek timely medical attention and follow the physician's diagnosis and treatment recommendations. At the same time, maintaining good lifestyle habits and a positive attitude can also help alleviate symptoms associated with pituitary tumors.   

What are the common symptoms of a pituitary tumor? In summary, the common symptoms of pituitary tumors are diverse, and their specific manifestations vary with individual differences and tumor characteristics. The treatment of pituitary tumors and their symptoms should be jointly determined by a multidisciplinary team comprising endocrinologists, neurosurgeons, and radiologists, and should be individually adjusted according to the patient's specific condition.   

The International Neurosurgeons Circle (INC) – World Advisory Neurosurgical Group (WANG) comprises numerous internationally renowned professors with exceptional surgical skills and extensive successful case experience. Among them is Professor Sebastien Froelich (France), former Chairman of the Skull Base Surgery Committee of the World Federation of Neurosurgical Societies (WFNS), who specializes in endoscopic endonasal skull base tumor resection. He performs minimally invasive surgery for complex brain tumors such as chordomas, craniopharyngiomas, and pituitary tumors in difficult‑to‑reach intracranial locations using neuroendoscopy. His patented "chopsticks" technique not only improves the resection rate but also leads to better prognostic outcomes for tumor patients.
