Pituitary tumors refer to a type of benign tumor that occurs at the site of the pituitary fossa. Generally, they grow relatively slowly. In the early stages of the disease, there are usually no obvious symptoms or signs. Some patients may occasionally feel mild headaches or dizziness, which most can tolerate. As the size of the pituitary tumor gradually increases, it often affects the surrounding critical tissues, nerves, and organs, primarily impacting pituitary function, thereby leading to pituitary hypofunction. This affects the secretion of endocrine hormones in the body, causing abnormal secretion of endocrine hormones, and resulting in a series of symptoms and signs. For example, male patients may experience abnormalities in the secretion of male hormones, leading to difficulties with erection, while female patients are likely to experience menstrual disorders and irregular menstruation.

What to do if a pituitary tumor recurs?

If a pituitary tumor recurs, there is no need to worry excessively. Instead, it is advisable to actively visit the local hospital for a cranial MRI with contrast to determine the specific location and severity of the recurrent pituitary tumor. Treatment plans should be decided based on the patient's condition. For patients who are eligible for surgery, it is recommended to opt for surgical removal of the pituitary tumor again. If the patient is elderly and frail and cannot withstand surgery, conservative treatment is recommended. Treatment can be carried out through medication or radiation therapy, among other methods, to help improve symptoms and enhance the quality of life.

Postoperative complications of pituitary tumor surgery

For patients with pituitary tumors, a range of complications, sequelae, or concomitant ailments can easily occur after surgery. For instance, postoperative sellar hematoma may occur, and some patients may even experience the rupture of a pseudoaneurysm. Additionally, some patients may repeatedly suffer from headaches, dizziness, nausea, vomiting, and weakness in the limbs after surgery, along with significant memory decline, reduced cognitive function—including calculating ability, and orientation in time, space, and person—gradually diminishing. These are considered postoperative sequelae of pituitary tumor surgery.

What should not be eaten with pituitary tumors?

For patients with pituitary tumors, it is advisable to be cautious about their diet in daily life. Try to avoid eating foods that are overly greasy, spicy, or irritating. It’s also best to limit or avoid consuming foods rich in cholesterol, carbohydrates, or fried foods. Additionally, women should avoid taking hormonal medications, especially short-acting hormonal drugs, as they can disrupt existing endocrine hormone balances, exacerbate symptoms, and lead to an increase in the size of the pituitary tumor. Furthermore, in daily life, avoid eating foods that may cause allergies, such as seafood products.

Is a pituitary tumor easy to treat?

Our current understanding of pituitary tumors is quite deep, and we have accumulated rich treatment experience in the pathogenesis, disease progression, and treatment of pituitary tumors. Therefore, it is recommended to use surgical methods for pituitary tumor patients, especially those with obvious symptoms. Clinically, it is generally recommended to choose the transnasal-transsphenoidal approach for a complete resection of the pituitary tumor. For most patients, this can achieve good therapeutic effects. Moreover, with the continuous advancement of diagnostic techniques, early detection and treatment of small early pituitary microadenomas through complete surgical resection can also achieve good therapeutic outcomes.

Is pituitary tumor surgery dangerous?

For patients with pituitary tumors, undergoing pituitary tumor surgery carries certain risks. The main risks are due to the important blood vessels, nerves, and various crucial structures around the pituitary tumor. Careless maneuvers during the surgery may damage these important organs or affect the surrounding crucial blood vessels, leading to potentially fatal massive bleeding. Additionally, some common surgical risks may also exist, such as anesthesia accidents, postoperative intracranial infections, cerebrospinal fluid rhinorrhea, and other conditions. Therefore, for pituitary tumor patients, it is necessary to prepare thoroughly for the surgery and make a comprehensive assessment of the patient's overall condition before the procedure.
