Plural ganglia
A compact group of nerve cells having a specific function. In invertebrate animals, pairs of ganglia occur at intervals along the axis of the body, with the forwardmost pair functioning like a brain. In vertebrates, ganglia are usually located outside the brain or spinal cord and control the functioning of the body's internal organs.

ganglion

A mass of nerve cell bodies outside the central nervous system.

17 Less common manifestations of zoster include the Ramsay-Hunt syndrome (involvement of the geniculate ganglion of the facial nerve) which manifests as vesicles in the external auditory canal and palate associated with loss of taste to the anterior two-thirds of the tongue and facial weakness.
This syndrome is a rare complication of herpes zoster that occurs when latent varicella zoster virus (VZV) infection reactivates and spreads to affect the geniculate ganglion.
They course through the external auditory canal, through the geniculate ganglion region and end in the fibrous tissue of Foramen Lacerum.
On MRI, intense enhancement of the right geniculate ganglion was noted with gadolinium contrast (figure 2).
If the lesion is proximal to the geniculation ganglion, the motor paralysis is accompanied by gustatory and autonomic abnormalities, while lesion between the geniculate ganglion and the origin of chorda tympani produces same effects, except that lacrimation is spared.
The ganglion is unable to extend neurites in isolation state as opposed to geniculate ganglion, dorsal root ganglion and other sensory cranial ganglia (Lumsden and Davies, 1983, 1986).
An additional two were serious ophthalmic herpes; this results when the virus, which remains latent and lifelong in the sensory ganglia, reactivates in the geniculate ganglion.
It occurs when VZV affects the geniculate ganglion of the facial nerve.
2] Facial nerve dehiscence (FND) is a common anatomic variant that usually occurs in the tympanic segment above the oval window but is also encountered at the level of the geniculate ganglion and in the mastoid segment adjacent to the retro facial cells.
10) Tumors usually infiltrate the facial nerve at the geniculate ganglion.
INTRODUCTION: Herpes zoster oticus also known as Ramsay Hunt syndrome (RHS) is a rare complication of herpes zoster in which reactivation of latent varicella zoster virus infection in the geniculate ganglion causes otalgia, auricular vesicles and peripheral facial paralysis.
Autopsy specimens have demonstrated the presence of both herpes simplex virus (HSV) and varicella zoster virus (VZV) in the geniculate ganglion.
