Cerebellopontine angle epidermoids presenting with trigeminal neuralgia

Trigeminal Neuralgia Caused by Pontocerebellar Angle Epidermoid Tumor: A Case Report and Review of Literature

“…In this study, it was reported that TN may be the first symptom of pontocerebellar corner epidermoid tumor, especially in teenagers (8). In the 25-patient pontocerebellar corner epidermoid tumor series by Mohanty et al, 13 patients had TN, among which 7 did not have any other symptom besides TN, and all of them benefited from surgery (9).…”

“…The important neural and vascular structures in the region, however, make it difficult. Cranial nerve dysfunction and aseptic meningitis are the most frequent complications of surgery (8). Leaving the capsule may cause recurrence but it would take a long time for these tumors since they grow very slowly.…”

“…On the contrary, Gio et al reported that the removal of the capsule that is stuck to the nerve is crucial in relieving the pain even though it may also cause nerve damage (10). In the epidermoid tumor cases that cause TN, it is recommended that the vascular compression in the root entry zone must be checked after the total excision, and that microvascular decompression must be performed if there is compression (7,8).…”

Epidermoid Tumors in the Cerebellopontine Angle Presenting with Trigeminal Neuralgia

“…Epidermoid tumors represent 0.2 to 1.4% of all primary intracranial tumors 11,15,16,21) . CPA epidermoids constitute 40% of all intracranial epidermoids 16) and the incidence of epidermoids among all CPA tumors is approximately 5% 11) .…”

Классическая Невралгия Тройничного Нерва

“…К та-ким заболеваниям относятся: опухоли мосто-мозжескового угла [67,145,181,211,244,248,287,319,347,348], арахноидиты задней че-репной ямки [142,323], аневризмы и артерио-венозные мальфор-мации вертебробазилярного бассейна [150,240,254,265,309,361,352,425], аномалии Арнольда-Киари [218,405], платибазии [264,357]. Клинически этот вид НТН отличается от классической нарастающим сенсорным дефицитом, не характерным для клас-сической НТН.…”
