Is pheochromocytoma a cancer?

Pheochromocytoma is not a cancer. It is a special type of tumor tissue that usually originates from the neuroectodermal chromaffin tissue. It can secrete catecholamines. Based on the specific origins of the tumor cells, it can be divided into types such as parasympathetic, paraganglioma, sympathetic, and ganglioneuroma. Most often, it presents with long-term hypertension, which can cause damage to the heart, brain, and kidneys due to prolonged hypertension, or severe increases in blood pressure can lead to hypertensive brain hemorrhage, thereby endangering the patient's life. Early treatment is often necessary.

Does hydrocephalus affect intelligence?

Mild hydrocephalus generally does not significantly affect intellectual levels, while moderate or severe hydrocephalus often impacts a patient’s intelligence. In children, it can cause severe impairment in intellectual development. For adults, it results in noticeable intellectual deficiencies, primarily characterized by significant cognitive dysfunction, reduced memory, diminished calculating abilities, and weakened verbal communication skills. Additionally, individuals may appear indifferent, speak less, are reluctant to interact with others, and have difficulty expressing themselves. Furthermore, most patients experience reduced orientation abilities concerning time, people, and space, which are predominantly caused by hydrocephalus.

Pheochromocytoma hypertension medication

For pheochromocytoma, it is often recommended to use adrenergic receptor blockers for the treatment of hypertension. These can be divided into α-adrenergic receptor blockers and β-adrenergic receptor blockers. In addition, all other types of antihypertensive drugs can also be used frequently during treatment. For example, angiotensin-converting enzyme inhibitors and calcium channel blockers also play a helpful role in the treatment of pheochromocytoma. Besides pharmacological treatment, the fundamental approach is to perform qualitative and localization diagnosis, and after confirmation, to surgically remove the pheochromocytoma completely to fundamentally achieve therapeutic goals.

Early symptoms of neuroblastoma

For patients with neuroblastoma, in the early stages, due to the small size of the tumor, there generally lacks clear clinical signs or symptoms. Most patients experience mild headaches, dizziness, nausea, and vomiting, accompanied by a certain degree of vertigo. However, in most cases, these symptoms can be tolerated. Patients often have episodic attacks, with a persistent worsening condition. Later, as the tumor grows further, it may lead to an exacerbation of existing symptoms such as headaches, dizziness, nausea, and vomiting. Some patients may also experience abnormalities in the sensation of one side of the body, manifested as numbness, pain, and a tingling sensation.

Precursors to cerebral infarction

For patients with cerebral infarction, before the onset of the illness, they often lack specific prodromal symptoms. Some patients may experience mild headaches, dizziness, nausea, and a clear feeling of discomfort. Additionally, some patients might experience numbness in the legs and involuntary twitching of facial muscles before the onset. Subsequently, some patients may also start to have drooping of the corner of the mouth to one side, drooling, slurred speech, and distinct articulation disorders. When these clinical presentations occur, it is necessary to be vigilant and seek timely medical attention at a local hospital. A cranial CT or MRI should be performed to confirm the diagnosis.

How is pheochromocytoma treated?

Currently, for the treatment of pheochromocytoma, it is primarily important that once diagnosed with pheochromocytoma, one should promptly visit the local hospital to arrange surgical treatment as soon as possible. By surgically removing the pheochromocytoma, this prevents the excessive secretion of catecholamines, which can lead to a hypertensive crisis in patients. Therefore, clinically, after diagnosing and locating the pheochromocytoma, receiving surgical treatment can often achieve satisfactory therapeutic outcomes. Typically, appropriate preparations must be made before surgery. Generally, prior to the operation, it is crucial to actively administer medications such as alpha-adrenergic blockers, beta-adrenergic blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, vasodilators, and catecholamine synthesis inhibitors to effectively treat and stabilize blood pressure.

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.

trigeminal neuralgia scope

The range of trigeminal neuralgia attacks is usually located in the sensory area of the trigeminal nerve root, broadly covering both sides of the patient's nostrils and around the corners of the mouth. The nature of the pain is quite severe, often described as knife-like pain or burning pain. The duration of each pain episode varies, often starting and stopping suddenly. Around the pain area, fixed trigger points are likely to form. Accidentally touching these trigger points while brushing teeth, washing faces, or rinsing mouths can often trigger an attack of trigeminal neuralgia. Over time, due to repeatedly triggering the pain by touching these points, patients may become afraid to wash their faces or brush their teeth, and may experience facial muscle numbness or atrophy.
