  2. Arachnoid cyst - Wikipedia

    en.wikipedia.org/wiki/Arachnoid_cyst

    Arachnoid cysts are cerebrospinal fluid covered by arachnoidal cells and collagen [1] that may develop between the surface of the brain and the cranial base or on the arachnoid membrane, one of the three meningeal layers that cover the brain and the spinal cord. [2] Primary arachnoid cysts are a congenital disorder whereas secondary arachnoid ...

  3. Central nervous system cyst - Wikipedia

    en.wikipedia.org/wiki/Central_nervous_system_cyst

    These classification of cysts are embedded in the endoderm (inner layer) and the ectoderm (outer layer) of the cranial or spinal cord germ layers.They normally take over the neuraxis, the axis of the central nervous system that determines how the nervous system is placed, which allows the cysts to infiltrate the CNS tissues. [3]

  4. Syringomyelia - Wikipedia

    en.wikipedia.org/wiki/Syringomyelia

    Syringomyelia is a generic term referring to a disorder in which a cyst or cavity forms within the spinal cord. Often, syringomyelia is used as a generic term before an etiology is determined. [3] This cyst, called a syrinx, can expand and elongate over time, destroying the spinal cord.

    Tarlov cysts are most commonly located in the S1 to S4/S5 region of the spinal canal, but can be found along any region of the spine.They usually form on the extradural components of sacrococcygeal nerve roots at the junction of dorsal root ganglion and posterior nerve roots and arise between the endoneurium and perineurium.

  6. Arachnoiditis - Wikipedia

    en.wikipedia.org/wiki/Arachnoiditis

    Arachnoiditis is an inflammatory condition of the arachnoid mater or 'arachnoid', one of the membranes known as meninges that surround and protect the central nervous system. The outermost layer of the meninges is the dura mater (Latin for hard) and adheres to inner surface of the skull and vertebrae. [ 1 ]

  8. Central nervous system disease - Wikipedia

    en.wikipedia.org/wiki/Central_nervous_system_disease

    Arachnoid cysts are cerebrospinal fluid covered by arachnoidal cells that may develop on the brain or spinal cord. [14] They are a congenital disorder, and in some cases may not show symptoms. However, if there is a large cyst, symptoms may include headache, seizures, ataxia (lack of muscle control), hemiparesis, and several others.

  9. Dural ectasia - Wikipedia

    en.wikipedia.org/wiki/Dural_ectasia

    Dural ectasia is defined as a ballooning or outpouching of the dura with a dural volume greater than two standard deviations above the mean value in controls. [9] It is usually identified by MRI or CT Scan, [7] which can be used to distinguish it from tumors. [16]
