This category of cysts takes over areas of necrotic tissue in the brain from injuries, diseases, or abnormalities, which occur due to the central nervous system's nonregenerative nature. These cysts can affect all germ layers of the CNS, but are most common in the arachnoid mater , and the ventricular space , which may block CSF pathways.
From their common origin at a joint or tendon, ganglion cysts may form in a wide range of locations. Rarely, intraosseous ganglion cysts occur, sometimes in combination with a cyst in the overlying soft tissue. [6] [16] Rare cases of intramuscular ganglion cysts in the gastrocnemius muscle of the calf have been reported.
Microsurgeon is one of the first published video games related to health or health education. [4] The player must guide a tiny medical device, the Robot Probe, throughout a patient's body to treat the ailments affecting various organs, such as bacterial infections, brain tumors, cholesterol blockages in arteries, and tapeworms.
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.

The term "ganglion" refers to the peripheral nervous system. [1] However, in the brain (part of the central nervous system), the basal ganglia are a group of nuclei interconnected with the cerebral cortex, thalamus, and brainstem, associated with a variety of functions: motor control, cognition, emotions, and learning.

Definitive treatment for ganglioglioma requires gross total surgical resection, and a good prognosis is generally expected when this is achieved. However, indistinct tumor margins and the desire to preserve normal spinal cord tissue, motor and sensory function may preclude complete resection of tumor.
The trigeminal ganglion contains cell bodies of the pseudo-unipolar sensory neurons of the trigeminal nerve which extend their axons both distally/peripherally into the three divisions of the trigeminal nerve on the one end, and proximally/centrally to the brainstem on the other end; the trigeminal root extends from the trigeminal ganglion to the ventrolateral aspect of the pons.
A ganglionectomy, also called a gangliectomy, is the surgical removal of a ganglion. [1] The removal of a ganglion cyst usually requires a ganglionectomy. Such cysts usually form on the hand, foot or wrist and may cause pain or impair body function. Aspiration of the cyst and steroid injections are typically
