Craniopharyngioma
Craniopharyngioma is a relatively rare benign tumor that occurs in the sellar region at the base of the skull. The age distribution is bimodal, with the highest incidence in children aged 5-14 years and adults aged 45-60 years.
View detailsTrigeminal neuralgia
Trigeminal neuralgia is the most common cranial nerve disorder, characterized by recurrent, brief, paroxysmal episodes of severe pain localized to the distribution of the trigeminal nerve (face, mouth, and jaw). This condition primarily affects adults and the elderly, with a higher incidence in women than in men.
View detailsIntraspinal tumor
Intraspinal tumors are primary or secondary tumors that originate in the spinal cord, spinal nerve roots, meninges, and tissues of the vertebral canal. They primarily manifest as paroxysmal pain and abnormal limb sensation. Based on their relationship with the spinal cord and dura mater, intraspinal tumors can be classified into intramedullary tumors, extramedullary intradural tumors, and extradural tumors. Intraspinal tumors are common diseases in neurosurgery and spinal surgery. They can occur at any age but are more prevalent in middle-aged individuals.
Acoustic neuroma
Acoustic neuroma, also known as vestibular schwannoma, is a benign tumor originating from the Schwann cells of the vestibular or cochlear branch of the auditory nerve. It is the most common type of intracranial neuroma, primarily presenting with symptoms such as tinnitus, hearing loss, vertigo, and facial numbness. This condition is more common in adults, with an incidence peak typically between 30 and 50 years of age.
View detailsHydrocephalus
Hydrocephalus is a condition characterized by the abnormal accumulation of cerebrospinal fluid (CSF) within the intracranial cavity, resulting from various etiologies. This condition is commonly observed in infants and adults over 60 years of age. In infants, the primary manifestations include an enlarged head circumference, irritability, and poor feeding. In adults, the main symptoms are headache, nausea, vomiting, and somnolence.
View detailsCerebral aneurysm
A cerebral aneurysm is a localized, abnormal enlargement of a cerebral artery wall, forming a sac-like protrusion. It is a cerebrovascular disease, not a tumor. Rupture of a cerebral aneurysm can be life-threatening, and its onset is often very sudden. The time interval from onset to treatment directly determines the treatment outcome. Once it ruptures and bleeds, the mortality and disability rates are extremely high. This disease is common in middle-aged and elderly individuals aged 40-60 years. The prevalence of unruptured cerebral aneurysms in the general population is approximately 2%-5%.
View detailsCerebral vascular malformation
Cerebral vascular malformation is a congenital vascular developmental anomaly, primarily characterized by irreversible changes in the structure and number of blood vessels. This leads to impaired blood supply to localized brain tissue, resulting in a series of complications. It is a general term for diseases including arteriovenous malformations, dural arteriovenous fistulas, capillary malformations, and cavernous malformations. This disease is common in young adults, with an average age of diagnosis between 20 and 40 years. In many cases, this disease presents without any clinical symptoms. Possible symptoms include headache, epilepsy, and neurological dysfunction.
View detailsGlioma
Glioma, also known as glial cell tumor or neuroglioma, is a class of the most common primary intracranial tumors, mainly divided into astrocytoma, glioblastoma, oligodendroglioma, medulloblastoma, ependymoma, etc. It is characterized by "three highs and one low", namely high incidence, high recurrence rate, high mortality rate, and low cure rate. Glioma can occur at any age, but it is most common in people aged 60-80 years.
View detailsMeningioma
The human skull and brain tissue are separated by three layers of membranes, collectively known as the meninges. From outermost to innermost, these are the dura mater, arachnoid mater, and pia mater. A meningioma is a type of brain tumor that originates from the arachnoid cap cells. Meningiomas can occur at any age but are rare in children. They are most common in individuals over 60 years old and are more prevalent in women than in men. Early stages often present without obvious symptoms, with symptoms developing later due to tumor compression. Common Questions Q: How serious is a meningioma? A: A meningioma is a common type of benign intracranial tumor. The severity of a meningioma depends on its size and location. If the tumor is small and located superficially, such as on the cerebral convexity, complete surgical resection is often possible, leading to a cure, and the condition is not considered serious. However, if the tumor is located in a deep area, such as the skull base, the condition is more serious because the tumor may adhere to surrounding blood vessels, nerves, and brain tissue, making complete surgical resection difficult. Surgery in these cases also carries a risk of severe complications such as hemiplegia, coma, or even death. Overall, the prognosis for the vast majority of meningiomas is very good.
