Nonspastic hemifacial spasm confirmed by abnormal muscle responses
BACKGROUND Hemifacial spasm is usually diagnosed by inspection which mainly identifies involuntary movements of orbicularis oculi. Assessing abnormal muscle responses (AMR) is another diagnostic method. CASE DESCRIPTION We report a case of left hemifacial spasm without detectable involuntary facial movements. The patient was a 48-year-old man with a long history of subjective left facial twit...
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 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 کاملCT and hemifacial spasm.
Forty-six patients with typical hemifacial spasm had CT. Thirty-eight (83%) were abnormal, including two with surgically documented tumors. Thirty-six had a characteristic dolichoectatic vertebrobasilar artery, with the convexity pointing to the side of the spasm in 92% of the scans. This study suggests that CT is worthwhile procedure in the evaluation of hemifacial spasm and that dolichoectati...
متن کاملHemifacial spasm in tuberculous meningitis.
Hemifacial spasm developed in a 47-year-old man with tuberculous meningitis. The spasms ceased completely following vigorous antituberculous treatment. A selective compression of the facial nerve root along its exit at the brainstem by a localised inflammatory process is the most tenable explanation for the development of the hemifacial spasm.
