1/4. facial pain as a presenting feature of intracerebral haemorrhage.A literature review from 1966 using medline with keywords 'cerebral haemorrhage' and 'facial pain' failed to reveal any cases in which facial pain was the initial feature of intracranial haemorrhage. The following case describes ipsilateral facial pain which is previously undescribed as a presentation of intracranial bleeding. A 53 year old female who was previously well, with no significant history of headache, developed right facial pain from the orbit to the maxilla. Ten to 15 min later she developed nausea and vomiting with unsteadiness and confusion. She had difficulty with left-hand fine finger movements, with normal sensation and reflexes but an extensor plantar response on the left. facial pain persisted for 3 days. Initial imaging revealed a 4 x 3 cm right temporal lobe haemorrhage with mass effect and oedema extending into the subarachnoid space. Angiogram revealed a right temporal lobe arteriovenous malformation. The basis of the pain remains speculative but includes sensation from the torn vessel wall being referred to the face and subarachnoid blood irritation of the meninges in the middle cranial fossa. Another possibility is irritation of somatosensory cortex II, but why this should result in only ipsilateral pain is unclear. facial pain should be an alerting symptom to the neurologist when it appears with no apparent cause.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/4. The association of hemifacial spasm and facial pain.The recognition of an association between trigeminal neuralgia and ipsilateral hemifacial spasm has been delayed by confusion over the nomenclature of the two conditions. Three patients are presented who had facial pain associated with hemifacial spasm. The findings on investigation of these patients, and an analysis of the literature, suggests that the combination is almost inevitably associated with pathological processes in the posterior fossa, particularly anomalous, ectatic or aneurysmal blood vessels.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/4. hemifacial spasm caused by a venous angioma. Case report.The authors describe the case of a 53-year-old woman who suffered from a hemifacial spasm caused by a venous angioma in the posterior fossa. At operation the parenchymal segment of the angioma was preserved and vascular decompression was performed by placing pieces of shredded Teflon between the vessel and nerve. After decompression the patient was completely free from spasm.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/4. facial pain in a case of cranial dystonia: a case report.A 76-year-old man had shown sustained excruciating facial pain in the maxillary region for more than 30 years. Since he was suffering from blepharospasm, facial electromyography was performed and revealed a perioral dystonia. This possible cause of facial pain might have been overlooked had dystonia not been considered and electromyographical studies performed. Repeated intramuscular perioral injections of botulinum toxin brought about complete pain relief. This case shows that involuntary activity of facial muscles can cause a severe chronic pain syndrome. Possible mechanisms include irritation of ascending trigeminal fibers, muscle ischemia due to compression of blood -vessels, or release of pain-producing substances.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
