1/65. Successful treatment of whiplash-type injury induced severe pain syndrome with epidural stimulation: a case report.Chronic severe cervico-facial pain syndrome associated with a whiplash-type injury was successfully treated with epidural spinal cord stimulation. The patient had been in pain for 9 years, responding temporarily only to stellate ganglion blocks. The patient has now been painless for 18 months. We have been unable to find a similar case reported in the literature to date.- - - - - - - - - - ranking = 1keywords = ganglion (Clic here for more details about this article) |
2/65. Intraosseous ganglion cysts of the ankle: a report of three cases with long-term follow-up.Three cases of intraosseous ganglion cysts of the ankle are presented with an average follow-up of 68 months (range, 48-78 months). review of the literature revealed 251 cases of intraosseous ganglion cysts, with 75 located in the ankle and a recurrence rate of 6.1%. In the three cases presented, a satisfactory long-term result was obtained with bone graft and curettage in two cases and currettage alone in one case. No recurrences or complications occurred.- - - - - - - - - - ranking = 6keywords = ganglion (Clic here for more details about this article) |
3/65. Mild gait abnormality and leg discomfort in a child secondary to extradural ganglioneuroma.Ganglioneuromas are benign and slow-growing tumors that most commonly originate from the sympathetic trunk. Ganglioneuromas often decrease in size and rarely require reoperation. Changes in gait or the onset of limb pain without a discernible local cause are indications for investigation of patients for possible intraspinal pathology. We report the case of a 5-year-old boy who presented with seemingly static symptoms, while the slow-growing tumor had enveloped nerve roots and caused bone destruction of the vertebrae.- - - - - - - - - - ranking = 4keywords = ganglion (Clic here for more details about this article) |
4/65. A ganglion cyst causing lumbar radiculopathy in a baseball pitcher: a case report.This report describes a case of a professional baseball pitcher who developed acute left lumbar radicular symptoms after a baseball game and was subsequently sidelined for the rest of the season. physical examination revealed depressed reflexes in the left posterior tibialis and left medial hamstring muscles, mild weakness in the left extensor hallucis longus, and positive dural tension signs. magnetic resonance imaging demonstrated an ovoid mass at the L4-L5 level, causing compression of the dura. Surgical resection of the mass resulted in resolution of his symptoms. pathology revealed that the mass was a ganglion cyst. A ganglion cyst is a rare cause of lumbar radiculopathy and should be considered in the differential diagnosis if a patient with lumbar radiculopathy fails to respond to conservative treatment.- - - - - - - - - - ranking = 6keywords = ganglion (Clic here for more details about this article) |
5/65. Sonographic imaging of a spinoglenoid cyst.Spinoglenoid cysts can be the reason for suprascapular nerve entrapment syndrome resulting an isolated atrophy of the infraspinatus muscle. The syndrome usually presents painless and is frequently observed in professional volleyball players. The incidence of these cysts in volleyballplayers is still unknown. diagnosis is made by neurological examination using electromyography and magnetic resonance imaging. Our case shows the potential of ultrasound as a possible imaging method of ganglion cysts that could be used as a screening method to prevent suprascapular neuropathy.- - - - - - - - - - ranking = 1keywords = ganglion (Clic here for more details about this article) |
6/65. Nonoperative treatment of an interosseous ganglion cyst.ganglion cysts of the knee are being reported more frequently secondary to an increased rate of magnetic resonance imaging studies. Although knee pain is the impetus for imaging, ganglion cysts are often incidental findings. Nonoperative treatment is a successful therapeutic option. We report a patient with variable pain presentations over the course of her treatment. The pattern of complaints pointed to different primary etiologies about the knee, but all were common to an interosseous ganglion cyst. A stepwise assessment and expansion of the differential diagnosis allowed for appropriate utilization of modalities and limited morbidity with nonoperative therapy.- - - - - - - - - - ranking = 6keywords = ganglion (Clic here for more details about this article) |
7/65. Different brain areas activated during imagery of painful and non-painful 'finger movements' in a subject with an amputated arm.The purpose of the present study was to investigate differences in brain activation with functional magnetic resonance imaging (fMRI) during imagery of painful and non-painful 'finger movements' and 'hand positioning' in a subject with an amputated arm. The subject was a right-handed man in his mid-thirties who lost his right arm just above the elbow in a car-train accident. MRI was performed with a 1.5 T Siemens Vision Plus scanner. The basic design involved four conditions: imagining 'painful finger movements', 'non-painful finger movements', 'painful hand positioning', 'non-painful hand positioning'. Imagery of finger movements uniquely activated the contralateral primary motor cortex which contains the classic 'hand area'. The lateral part of the anterior cerebellar lobe was also activated during imagery of finger movements. Imagery of pain uniquely activated the somatosensory area, and areas in the left insula and bilaterally in the ventral posterior lateral nucleus of the thalamus. It is suggested that the insula and thalamus may involve neuronal pathways that are critical for mental processing of pain-related experiences, which may relate to a better understanding of the neurobiology of phantom limb pain.- - - - - - - - - - ranking = 0.012342473383275keywords = nucleus (Clic here for more details about this article) |
8/65. Perineural tumor spread along the auriculotemporal nerve.BACKGROUND AND PURPOSE: Evaluation of images of perineural tumor spread in patients with head and neck malignancies is essential for planning treatment and determining the patient's prognosis. Although the communications between the facial and trigeminal nerves are not widely known, they may provide a route for tumor growth. The purpose of this study was to elucidate the course of the auriculotemporal nerve, as well as the clinical and imaging findings that suggest involvement of the communication between the facial nerve and the mandibular division (V(3)) of the trigeminal nerve. methods: Images in 15 patients with clinical or radiologic findings suggestive of perineural tumor spread along the auriculotemporal nerve were reviewed. Involvement of the main trunk of the facial nerve, auriculotemporal nerve, V(3), trigeminal cistern, and ganglion and adjacent anatomic structures were noted in each patient. RESULTS: The course of the auriculotemporal nerve was described in detail. More than 50% of patients with perineural tumor spread along the auriculotemporal nerve had clinical signs of auriculotemporal nerve dysfunction, including periauricular pain and temporomandibular joint (TMJ) dysfunction or tenderness. Images in 13 of 15 patients with such tumor spread demonstrated findings of tumor growth along V(3.). CONCLUSION: knowledge of the course of the auriculotemporal nerve is critical in evaluating images for findings of tumor spread along this nerve. Periauricular pain, TMJ dysfunction or tenderness, and imaging signs of V(3) involvement are important indicators of potential involvement of the auriculotemporal nerve.- - - - - - - - - - ranking = 1keywords = ganglion (Clic here for more details about this article) |
9/65. Thalamic field potentials during deep brain stimulation of periventricular gray in chronic pain.Stimulation of the central gray matter areas has been used for the treatment of chronic pain for decades. To better understand the mechanism of action of such treatment we studied the effects of stimulation of the periventricular gray (PVG) on the sensory thalamus in two patients with chronic central pain. In each case, two electrodes were implanted in the PVG (Medtronic 3389) and the ventroposterolateral thalamic nucleus (Medtronic 3387), respectively, under guidance of CT/MRI image fusion. The PVG was stimulated in the frequency range of 2-100 Hz in alert patients while pain was assessed using the McGill-Melzack visual analogue scale. In addition, local field potentials (FPs) were recorded from the sensory thalamus during PVG stimulation. Maximum pain relief was obtained with 5-25 Hz stimulation while 50-100 Hz made the pain worse. This suggests that pain suppression was frequency dependent. Interestingly, we detected low frequency FPs at 0.2-0.4 Hz closely associated with the pain. During 5-25 Hz PVG stimulation the amplitude of this potential was significantly reduced and this was associated with marked pain relief. At the higher frequencies (50-100 Hz) however, there was no reduction in the FPs and no pain suppression. We have found an interesting correlation between thalamic activity and chronic pain. This curious low frequency potential may provide an objective index for quantifying chronic pain, and may hold further clues to the mechanism of action of PVG stimulation.- - - - - - - - - - ranking = 0.012342473383275keywords = nucleus (Clic here for more details about this article) |
10/65. Treatment of a large intraosseous talar ganglion by means of hindfoot endoscopy.We report on 2 patients with a large intraosseous ganglion of the talus who were treated by means of a 2-portal endoscopic approach of the hindfoot with the patient in the prone position. By means of this approach, it is possible to visualize, debride, and graft a large intraosseous talar lesion. In both patients, the lesions were treated successfully, with no recurrence at follow up.- - - - - - - - - - ranking = 5keywords = ganglion (Clic here for more details about this article) |
