View detailsTarlov cyst
A sacral cyst refers to a cystic lesion occurring within the sacral canal, including perineural cysts, arachnoid cysts, and meningeal cysts. Most patients are asymptomatic. However, when the cyst compresses the surrounding cauda equina nerves, it can lead to symptoms such as pain, numbness, and weakness in the sacrococcygeal region and lower extremities, bowel and bladder dysfunction, and sexual dysfunction.
View detailsTethered cord syndrome
Tethered cord syndrome is a general term describing a specific abnormal state of the spinal cord and its related symptoms. It is caused by various etiologies that lead to the spinal cord being stretched, reducing its physiological range of motion. This often results in a low-lying conus medullaris, pathophysiological abnormalities of the conus medullaris, and manifestations of genitourinary, neurological, and/or musculoskeletal dysfunction. Tethered cord syndrome typically presents in childhood, with a small number of cases occurring in adulthood.
Glossopharyngeal neuralgia
Glossopharyngeal neuralgia is a paroxysmal, severe pain caused by irritation of the glossopharyngeal nerve. It has a sudden onset and manifests as sharp, knife-like, or electric shock-like pain, primarily occurring on one side of the tongue base, pharynx, tonsils, ear root, and posterior mandible. The incidence is higher in males than in females, and the typical age of onset is over 40 years.
View detailsPeripheral nervous system tumors
The nervous system is artificially divided into two major systems: the central and peripheral nervous systems. The central nervous system refers to the brain and spinal cord, while the nerves originating from the brain and spinal cord are called the peripheral nervous system. Peripheral nervous system tumors refer to tumors that occur in all neural structures outside the brain and spinal cord, including malignant schwannoma, ganglioneuroma, pigmented malignant schwannoma, plexiform neurofibroma, and malignant Triton tumor. These tumors are common in young and middle-aged adults, while neuroblastoma is more common in children.
View detailsMedulloblastoma
Medulloblastoma is a fast-growing malignant tumor of the cerebellum, which is located in the back of the brain, also known as the posterior fossa. It is common in children, and its main manifestations include headache, nausea, vomiting, balance disorders, and double vision (diplopia).
View detailsSpinal vascular malformation
Spinal vascular malformation refers to a vascular lesion formed by congenital developmental abnormalities of blood vessels located within, on the surface of, or near the spinal cord. This disease primarily affects the spinal cord blood vessels but can cause abnormalities in systemic neurological function.
View detailsChordoma
Chordoma is a rare, slow-growing malignant bone tumor, affecting less than one in 100,000 people. It typically occurs in the spine or skull base. Metastasis occurs in 30% to 40% of chordoma patients, especially in advanced stages, with lung metastasis being the most common. It can occur at any age, but the vast majority of chordomas occur in adults, with a higher incidence in males than females.
