“…The geniculate ganglion fossa is the most common location for facial nerve neurinoma [3,4]. They have reported that facial neurinoma originating in the geniculate ganglion fossa often shows extension to the tympanic and/or labyrinthine segments and that isolated involvement of the geniculate ganglion fossa at the time of the presentation is very rare.…”

“…[ 16 ] Facial nerve schwannoma [ Figure 10 ] can involve any of these segments among which geniculate ganglion is the most common location. [ 17 ] Clinical presentation is via facial nerve paresis. Differential diagnoses include cerebellopontine angle meningioma, schwannoma of other lower cranial nerves, epidermoid and the perineural spread of metastases.…”

Schwannomas are peripheral nerve sheath tumours arising from cranial, spinal or peripheral nerves. Most of the schwannomas are benign with the rare possibility of malignant transformation. Cranial nerve schwannomas can be seen along the course of any cranial nerve in the intracranial region or head and neck location. Although a majority are solitary sporadic lesions, multiple schwannomas can be seen in syndromes like neurofibromatosis type 2 and rarely in type 1. Since intracranial schwannomas are slow-growing, clinical presentation varies between no symptoms to cranial nerve palsy. Most of the times, the symptoms are due to mass effect over the adjacent structures, foraminal widening, compression of other cranial nerves, denervation injury or hydrocephalus. Familiarity with the course of the cranial nerves, imaging appearances and clinical presentation of schwannomas helps in accurate diagnosis and possible differential diagnosis, especially in uncommon clinical and radiological appearances. In this pictorial review, we illustrate relevant anatomy of cranial nerves, imaging features of schwannomas of most of the cranial nerves, clinical presentation and differential diagnosis.

“…Tipik olarak multisegment tutulumu izlenir ve genikulat ganglion en sık tutulum yeridir [118,119]. Fasiyal sinir schwannomunda fasiyal sinir paralizisi, sensörinöral işitme kaybı ve iletim tipi işitme kaybı semptomları izlenebilir.…”
