1/33. ophthalmoplegic migraine and periodic migrainous neuralgia, migraine variants with ocular manifestations.The spectrum of migraine has been outlined with particular attention to two entities: ophthalmoplegic migraine and Periodic Migrainous Neuralgia. Although quite different in many respects from classical migraine, the relationship of a periodic localized vascular phenomenon giving rise to headache and transient neurologic signs, classify PMN and OPGM as migraine variants. Supportive of this concept, the literature has been reviewed in both entities, and some observations are made on the validity of earlier reports. It is the author's opinion that Raeder's syndrome should be reserved for patients with a lesion localizing in the paratrigeminal area. This does not exclude migraine as an etiologic agent but also recognizes tumors, infections and fractures as being more common.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
2/33. morphine-induced ventilatory failure after spinal cord compression.We describe a patient who required large doses of parenteral morphine for severe pain secondary to epidural spinal cord compression caused by metastatic cancer. The pain improved suddenly after neurological progression to a complete cord compression. Shortly afterwards, the patient developed acute respiratory depression caused by an apparent relative overdose of morphine. Our hypothesis is that the cord compression relieved the pain by interrupting the nociceptive pathway. The dose of morphine was then physiologically excessive once the neurologic damage was completed and the pain had been relieved. We advise caution in patients receiving high doses of opioids in which a change in disease status or a pain-relieving intervention may produce rapid pain relief.- - - - - - - - - - ranking = 257.78741102705keywords = compression (Clic here for more details about this article) |
3/33. Bilateral median nerve compression at the level of Struthers' ligament. Case report.Struthers' ligament syndrome is a rare cause of median nerve entrapment. Bilateral compression of the median nerve is even more rare. It presents with pain, sensory disturbance, and/or motor function loss at the median nerve's dermatomal area. The authors present the case of a 21-year-old woman with bilateral median nerve compression caused by Struthers' ligament. She underwent surgical decompression of the nerve on both sides. To the authors' knowledge, this case is the first reported bilateral compression of the median nerve caused by Struthers' ligament. The presentation and symptomatology of Struthers' ligament syndrome must be differentiated from median nerve compression arising from other causes.- - - - - - - - - - ranking = 331.44095703477keywords = compression (Clic here for more details about this article) |
4/33. Saphenous neuralgia after arthroscopically assisted anterior cruciate ligament reconstruction with a semitendinosus and gracilis tendon graft.A case report of saphenous neuralgia following arthroscopically assisted anterior cruciate ligament reconstruction with hamstring tendons is presented. The patient complained of paresthesia in the anteromedial region of the lower leg and tenderness at the medial side of the knee without motor or reflex abnormalities. Because saphenous neuralgia can mimic disorders of the knee, peripheral vascular disease, and lumbar nerve root compression, diagnosis can be confirmed by anesthetic blockade. The patient underwent saphenous neurolysis. Six months after surgery, the patient had normal cutaneous sensation at the medial aspect of the lower leg and ankle and she no longer complained of any painful dysesthesia. To minimize the risk of damaging the saphenous nerve when harvesting hamstring tendons, the knee should be flexed and the hip external rotated.- - - - - - - - - - ranking = 36.826773003864keywords = compression (Clic here for more details about this article) |
5/33. The value of MR neurography for evaluating extraspinal neuropathic leg pain: a pictorial essay.SUMMARY: Fifteen patients with neuropathic leg pain referable to the lumbosacral plexus or sciatic nerve underwent high-resolution MR neurography. Thirteen of the patients also underwent routine MR imaging of the lumbar segments of the spinal cord before undergoing MR neurography. Using phased-array surface coils, we performed MR neurography with T1-weighted spin-echo and fat-saturated T2-weighted fast spin-echo or fast spin-echo inversion recovery sequences, which included coronal, oblique sagittal, and/or axial views. The lumbosacral plexus and/or sciatic nerve were identified using anatomic location, fascicular morphology, and signal intensity as discriminatory criteria. None of the routine MR imaging studies of the lumbar segments of the spinal cord established the cause of the reported symptoms. Conversely, MR neurography showed a causal abnormality accounting for the clinical findings in all 15 cases. Detected anatomic abnormalities included fibrous entrapment, muscular entrapment, vascular compression, posttraumatic injury, ischemic neuropathy, neoplastic infiltration, granulomatous infiltration, neural sheath tumor, postradiation scar tissue, and hypertrophic neuropathy.- - - - - - - - - - ranking = 36.826773003864keywords = compression (Clic here for more details about this article) |
6/33. Occipital neuralgia secondary to hypermobile posterior arch of atlas. Case report.The authors report on the management of occipital neuralgia secondary to an abnormality of the atlas in which the posterior arch was separated by a fibrous band from the lateral masses, resulting in C-2 nerve root compression. The causes and treatments of occipital neuralgia as well as the development of the atlas are reviewed.- - - - - - - - - - ranking = 36.826773003864keywords = compression (Clic here for more details about this article) |
7/33. Sudden unconsciousness during a lesser occipital nerve block in a patient with the occipital bone defect.Occipital nerve block is usually considered to be a very simple and safe regional anaesthetic technique. We describe a case of sudden unconsciousness during a lesser occipital nerve block in a patient with an occipital bone defect. A 63-year-old man complained of headache, which was localized to the right occipital region. A right lesser occipital nerve block with a local anaesthetic was performed for treatment. During the lesser occipital nerve block, the patient suddenly became disturbed and lost consciousness. Two hours after the incident, the patient was fully awake without neurological sequelae. He had previously undergone a microvascular decompression for right trigeminal neuralgia. The patient had a bone defect following craniotomy. We believed that the loss of consciousness during lesser nerve block may be due to a subarachnoid injection. Occipital nerve block is relatively contraindicated in the presence of a bone defect.- - - - - - - - - - ranking = 36.826773003864keywords = compression (Clic here for more details about this article) |
8/33. Familial trigeminal neuralgia: case reports and review of the literature.The paroxysmal facial pain of trigeminal neuralgia is usually idiopathic, but familial cases have been described. We describe a family with apparent autosomal dominant transmission of trigeminal neuralgia. Our cases and a review of the literature suggest that the etiology of trigeminal neuralgia may be vascular compression of the fifth cranial nerve. Autosomal dominant vascular and epileptic disorders are reviewed, and possible relationships to familial trigeminal neuralgia are considered.- - - - - - - - - - ranking = 36.826773003864keywords = compression (Clic here for more details about this article) |
9/33. Iatrogenic acute spinal epidural abscess with septic meningitis: MR findings.A contaminated catheter used in epidural anesthesia in a 71-year-old female produced acute epidural abscess and septic meningitis. methicillin-resistant staphylococcus aureus (MRSA) was detected in a culture of the epidural pus. Both T1- and T2-weighted MR images showed low intensity mass lesion compressing the thecal sac behind the vertebral body L3. The low intensity lesion was probably pus with gas component. In these low intensity lesions in MR findings with gas component, MR was superior to myelography because it visualized both the degree of compression to the thecal sac and extension of the lesion in all directions.- - - - - - - - - - ranking = 36.826773003864keywords = compression (Clic here for more details about this article) |
10/33. Surgical treatment of trigeminal neuralgia.trigeminal neuralgia, which is unilateral electric shock or knifelike pain occurring in one or more branches of the trigeminal nerve, is evoked by stimulation of the face, lips, or gums caused by activities such as shaving, brushing the teeth, or moving trigger zones. IT GENERALLY IS ACCEPTED that classic trigeminal neuralgia is a consequence of vascular compression and demyelination of the trigeminal nerve. Although medical therapy is available, it gradually becomes less effective because of the progressive nature of trigeminal neuralgia. MICROVASCULAR decompression of the trigeminal nerve to treat trigeminal neuralgia is discussed in this article. perioperative care, expected course of recovery, and potential complications are described.- - - - - - - - - - ranking = 36.826773003864keywords = compression (Clic here for more details about this article) |
