Imaging of Neurovascular Compression Syndromes: Trigeminal Neuralgia, Hemifacial Spasm, Vestibular Paroxysmia, and Glossopharyngeal Neuralgia.
Neurovascular compression syndromes are usually caused by arteries that directly contact the cisternal portion of a cranial nerve. Not all cases of neurovascular contact are clinically symptomatic. The transition zone between the central and peripheral myelin is the most vulnerable region for symptomatic neurovascular compression syndromes. Trigeminal neuralgia (cranial nerve V) has an incidenc...
متن کاملRadiography of trigeminal neuralgia and hemifacial spasm.
Radiographic findings in 68 patients with trigeminal neuralgia and 24 patients with hemifacial spasm are reviewed. The relative value of various radiographic diagnostic procedures is discussed. Trigeminal neuralgia and hemifacial spasm are usually caused by vascular compression of the trigeminal root entry zone and facial nerve exit zone respectively. Computed tomography (CT) of the posterior f...
متن کاملCombined hyperactive dysfunction syndrome of the cranial nerves: trigeminal neuralgia, hemifacial spasm, and glossopharyngeal neuralgia: 11-year experience and review.
OBJECTIVE A pathological condition caused by vascular compression at the root entry/exit zone of the cranial nerves is designated hyperactive dysfunction syndrome (HDS) of the cranial nerves. Patients with HDS who exhibited a combination of trigeminal neuralgia (TN), hemifacial spasm (HFS), and/or glossopharyngeal neuralgia were retrospectively reviewed, to study the incidence, etiological fact...
متن کاملTic convulsif: the association of trigeminal neuralgia and hemifacial spasm.
intra-uterine pregnancy of 19 weeks gestation. All along the size of the uterus was bigger than the period of amenorrhoea suggested. The foetal movements were first felt in the second week of January 1971 at 18 weeks gestation (uterine size 22 weeks). She developed mild hypertension on 2 April 1971 and was admitted for rest. An X-ray of the abdomen then revealed a twin pregnancy. The following ...
متن کاملHemifacial Spasm and Neurovascular Compression
Hemifacial spasm (HFS) is characterized by involuntary unilateral contractions of the muscles innervated by the ipsilateral facial nerve, usually starting around the eyes before progressing inferiorly to the cheek, mouth, and neck. Its prevalence is 9.8 per 100,000 persons with an average age of onset of 44 years. The accepted pathophysiology of HFS suggests that it is a disease process of the ...
