The authors report a case of cerebellopontine angle epidermoid presenting as typical hemifacial spasm. A 33-year-old male had experienced intermittent right hemifacial spasm for 2 years. Cranial nerve examination was otherwise normal, including auditory and trigeminal nerve functions. Metrizamide
A case of hemifacial spasm associated with a benign parotid tumor is reported. Excision of the tumor relieved the symptoms.
Flexor spasms are involuntary muscle contractions comprising dorsiflexion at the ankle and flexion at the knee and the hip, occurring as a result of nociceptive spinal release reflex. The presence of flexor spasms generally suggests a lesion in the spinal cord. Foot drop is usually seen with lesions
Ephaptic transmission is one of the electrophysiological hallmarks of hemifacial spasm. It is generally accepted that in the majority of patients with idiopathic hemifacial spasm, microvascular compression of the facial nerve at the site where the nerve exits the brain stem is the underlying cause.
Hemifacial spasm (HFS) is almost always induced by vascular compression but in some cases the cause of HFS are tumors at cerebellopontine angle (CPA) or vascular malformations. We present a rare case of hemifacial spasm caused by epidermoid tumors and the possible pathogenesis of HFS is discussed. A
Hemifacial spasm is a movement disorder characterized by involuntary paroxysmal chronic contractions of the facial musculature. The usual cause is simple vascular compression of the facial nerve, at its root exit zone of the brain stem. Previously only a case of hemifacial spasm associated with a
In clinical pediatric neurosurgery practice, fourth ventricle and cerebellar tumors are not rare. However, reports of secondary refractory hemifacial spasm are very rare. No report is currently available on the treatment of hemifacial spasm secondary to fourth ventricle and cerebellar tumors in
Hemifacial spasm (HFS) due to intracranial mass lesions is rare. Most cases are thought to be due to compression of the facial nerve by small vessels near the root of the facial nerve. A survey was undertaken of all botulinum toxin investigators to determine the incidence of imaged mass lesions
In this short case-illustrated review we aimed to analyse the possible nuances of hemifacial spasm (HFS) as the presenting symptom of a tumour of the fourth ventricle. The issue is remarkable since HFS can be secondary to a fourth ventricle tumour, even when no other neurological signs are reported.
A 53-year-old man with left lung cancer underwent left upper lobectomy and extended mediastinal lymphadenectomy. Shortly before the end of the operation, electrocardiogram showed elevation of ST wave and multiple ventricular premature contractures first, then ventricular fibrillations, and finally
A 47-year-old man presented with right parotid swelling and a history of frequent attacks of hemifacial spasm. MRI of the brain and neck showed a mass in the right parotid gland. Fine needle aspiration biopsy of the mass revealed a pleomorphic adenoma of the parotid gland, which was confirmed after
Tumor-related hemifacial spasm (HFS) has been found to be rare. During the period from October 1984 to October 2008, we treated 6,910 HFS patients using a microsurgical procedure. Of these HFS patients, 55 cases were associated with cerebellopontine angle tumors. A small craniectomy was performed in
Hemifacial spasm (HFS) is rarely due to serious compressive lesions, such as tumors, aneurysms, or vascular malformations, located in the cerebellopontine angle. Because of the interesting association of HFS with epidermoid tumors, we reviewed the records of all patients with HFS and all patients
Hemifacial spasm (HFS), one of the most common hyperactive cranial rhizopathies, is a disorder characterized by spontaneous, intermittent, and repetitive contraction of unilateral facial muscle. The most common cause of HFS is a mechanical compression of the facial nerve at the root Thirty-eight years old male patient. Accepted the radical thyroidectomy for thyroid cancer in our department. When surgery was ended, laryngeal spasm occurred during pulling out the tracheal intubation, the quick check of calcium was 1.87 mmol/L, after intravenous injection the calcium gluconate the
