Geniculate ganglion meningioma

Pediatric Radiology, 1997
Primary ectopic meningiomas are rare, but may be seen in the head and neck region. The temporal bone and its neural foramen are rarely the site of a primary meningioma. This report describes the CT and MRI appearance of an ectopic meningioma arising at the anatomic location of the geniculate ganglion, and discusses the differential diagnosis as well as

The Ultrastructure of the Geniculate Ganglion

Acta Oto-Laryngologica, 1982
The ultrastructure of the geniculate ganglion was studied in the guinea pig and monkey. Two cytologically distinct colonies of ganglion cells were seen and identified as light and dark cells. All neurons were unmyelinated and most were unipolar, although a few bipolar cells were seen. The axons, upon leaving the cell bodies, followed convoluted courses

Haemangiomas of the Geniculate Ganglion

Acta Otorrinolaringologica (English Edition), 2007
About 60 cases have been published since Pulec first described hemangiomas of the geniculate ganglion. They usually cause facial weakness even when they are very small. In cases of insidious evolution of facial paralysis, MRI, and CT are very helpful to rule out these tumors.

Endoscopic approach to geniculate ganglion: a multicentric experience

European Archives of Oto-Rhino-Laryngology, 2023
A variety of lesions could arise from the GG area, or extend into this region from adjacent sites. The management of perigeniculate lesions includes observation, surgery, and radiation, according to the nature, the size of the lesion, and the accompanying symptoms.

Geniculate Ganglion Anatomy for the Otologist

Archives of Otolaryngology - Head and Neck Surgery, 1969
THE greater (superficial) petrosal nerve and the geniculate ganglion are major anatomic landmarks in the surgical approach to the internal auditory canal through the middle cranial fossa. 1 The dura is elevated from the superior surface of the temporal bone through a craniectomy just above the root of the zygomatic process.

Neurotrophin receptors in the geniculate ganglion

Molecular Brain Research, 1999
We examined the distribution of the high affinity neurotrophin receptors (trkA, trkB, and trkC) in the rat geniculate ganglion. Previous work had shown that during early (prenatal) development, trkB and its two ligands, BDNF and NT-4/5, were most important for survival of almost all neurons.

Cavernous angioma of the geniculate ganglion

Journal of Neurosurgery, 2008
Intracranial extraaxial cavernous angiomas are rare vascular malformations. Their occurrence at the geniculate ganglion of the facial nerve within the temporal bone is exceptional. The authors describe a 35-year-old man who developed a slowly progressing facial palsy. Initial cranial MR imaging showed no pathological findings, but 2 years later another

Sensory Neurons in the Human Geniculate Ganglion

Cells Tissues Organs, 2017
The geniculate ganglion (GG) contains visceral and somatic sensory neurons of the facial nerve. In this study, the number and cell size of sensory neurons in the human GG were investigated. The estimated number of GG neurons ranged from 1,580 to 2,561 (mean ± SD = 1,960 ± 364.6).

Absence of Bone over the Geniculate Ganglion

Journal of Neurosurgery, 1968
D ANDY recognized that the geniculate ganglion "occasionally" protrudes through a congenital defect in the roof of the petrous temporal bone. In their book on trigeminal neuralgia, Stookey and Ransohoff 16 noted that in rare instances the petrous bone is defective over the geniculate ganglion.
