Pituitary tumor
Pituitary tumor examination items
For patients with pituitary tumors, it is first recommended to perform a cranial CT or MRI examination, and if necessary, a cranial MRI with contrast and a pituitary MRI with contrast can be done to help determine the specific location, size, and relationship of the pituitary tumor with surrounding important blood vessels and nerves. Additionally, blood tests are needed to examine the levels of endocrine hormones in the body, including cortisol, growth hormone, prolactin, thyroid hormones, and other related hormone levels. Furthermore, further examinations of the patient's cardiopulmonary function, such as electrocardiograms, echocardiograms, and chest CT scans, are also required.
Is pituitary tumor surgery done under general anesthesia?
For patients with pituitary tumors, general anesthesia is typically recommended for surgery. Clinically, a combined inhalational and intravenous anesthesia approach is adopted for treatment. Before surgery, anesthesia induction is carried out to stabilize the patient, who then undergoes tracheal intubation for general combined anesthesia. As the surgery nears completion, appropriate medication may be used to help shorten the anesthesia process. After the surgery is fully completed, the patient is transferred to the recovery room. Once the anesthetic drugs are gradually metabolized and consciousness returns to clarity, the tracheal tube is effectively removed.
How many days of hospitalization for pituitary tumor surgery?
For patients with pituitary tumors, it normally takes about one to two weeks to undergo surgery and be hospitalized. After surgery, it is appropriate for patients to rest in bed and refrain from getting up too early, mainly to monitor for any occurrence of cerebrospinal fluid rhinorrhea. Premature activity might lead to cerebrospinal fluid rhinorrhea or even trigger intracranial infections. Additionally, after surgery, it is important to perform blood tests to check the levels of endocrine hormones in the body, primarily to assess whether important electrolyte and hormone levels are normal. If there are abnormalities, adjustments should be made promptly, and discharge can be considered once the patient's condition is stable.
How to check for pituitary tumors?
For the examination of pituitary tumors, it can be conducted jointly through various methods such as inquiring about the patient's medical history based on symptoms and signs, as well as conducting endocrine and radiological examinations. Currently, with the continuous advancement in modern endocrinology, the use of endocrine radiology immunodiagnostic methods allows for the direct measurement of various hormones from the pituitary and hypothalamus, and functional tests of the pituitary can be performed. This helps in understanding whether there is hyperfunction in the pituitary and target organs, and provides an effective evaluation of early diagnosis of pituitary tumors, changes before and after treatment, and treatment efficacy, which is of significant importance. Additionally, judgments can also be made jointly through various methods such as cranial CT, cranial MRI, and enhanced MRI scanning of the pituitary gland.
Is a 2cm pituitary tumor big?
In the case of pituitary tumors, if the size reaches two centimeters, it is relatively large. Under normal circumstances, pituitary tumors can be classified into several types based on their size: microadenomas are generally smaller than one centimeter, macroadenomas are larger than 1.0 centimeter, and giant adenomas are larger than 3.0 centimeters. Usually, a two-centimeter pituitary tumor is already considered a macroadenoma. Normally, such large pituitary tumors often compress the surrounding pituitary tissue, causing hypofunction of the pituitary tissue and significant hormonal disturbances, which can lead to a range of uncomfortable symptoms and signs in patients.
Pituitary tumors are located in the pituitary gland.
Pituitary tumors are benign tumors that grow slowly, mostly within the pituitary fossa. Due to their proximity to the pituitary gland, small pituitary tumors generally do not show obvious symptoms. However, as the tumor size increases, it can easily compress the pituitary gland, affecting its function, resulting in pituitary dysfunction and causing an endocrine hormone disorder. This leads to a variety of symptoms and signs in patients. A cranial CT or MRI, including an enhanced MRI scan of the pituitary, can reveal a high-density shadow in the pituitary fossa, indicating the presence of an intracranial mass.
Is a pituitary tumor scary?
For pituitary tumors, if not treated promptly and effectively, the continuous enlargement of the tumor often causes patients to experience recurring symptoms such as headaches, dizziness, nausea, and vomiting. Additionally, a series of endocrine hormone imbalances accompanying the tumor often manifest various symptoms and signs. When the pituitary tumor grows to a certain size, it can also potentially cause pituitary apoplexy. Therefore, it is advisable for patients with pituitary tumors to seek timely medical attention at local hospitals and undergo early surgical treatment. By opting for endonasal transsphenoidal surgery to completely remove the pituitary tumor, most patients can achieve very good treatment outcomes, with a gradual alleviation of existing symptoms.
Is a pituitary tumor easy to treat?
Currently, the treatment technology for pituitary tumors is relatively mature. For early-stage pituitary microadenomas that are only a few millimeters in size, and where vision and visual fields are not yet affected, a definite diagnosis can be made. Under the surgical microscope, complete removal surgery is achievable, and it is possible to preserve the normal function of the pituitary gland. As surgical experience continues to increase, not only can tumors within the sella be removed, but even large adenomas or giant pituitary adenomas growing above the sella can be safely excised. Therefore, for patients with pituitary tumors, it is advisable to choose to visit a local hospital as early as possible and opt for a complete removal of the pituitary tumor through a transnasal transsphenoidal approach.
What is a pituitary tumor?
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.
Can pituitary tumors be cured?
Currently, for the treatment of pituitary tumors, it is generally recommended in clinical practice to opt for a complete resection via a transnasal-transsphenoidal approach. Most patients can achieve good therapeutic outcomes through surgery. The main goals of surgically treating pituitary tumors are to remove the tumor, decompress the visual pathways, and help restore and maintain the function of the pituitary and other neurological functions. Most patients can achieve good therapeutic results after treatment. Additionally, after receiving treatment, patients' original symptoms gradually alleviate or even disappear, and no longer worsen. Therefore, from this perspective, it is recommended that all symptomatic pituitary tumor patients should timely seek medical consultation at local hospitals and receive early treatment.
