1/33. Anomaly of the axis causing cervical myelopathy. Case report.Although the craniovertebral junction is one of the most common sites at which anomalies develop, spina bifida occulta of the axis (C-2) associated with cervical myelopathy is extremely rare. The authors present the case of a 46-year-old man who developed progressive tetraparesis caused by a cervical canal stenosis at the level of the axis. The spinal cord was compressed by an invaginated bifid lamina of the axis. The patient made a remarkable recovery after undergoing decompressive laminectomy of C-3 and removal of the bifid posterior arch of the axis.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
2/33. Atlantal stenosis: a rare cause of quadriparesis in a child. Case report.The authors report the case of a 3-year-old boy who suffered from quadriparesis and respiratory distress after failing to execute a somersault properly. neuroimaging revealed spinal cord contusion with marked spinal canal stenosis at the level of the atlas. No subtle instability, occult fracture, or other congenital abnormalities were confirmed. Spinal cord contusion with marked canal stenosis is rare, and only several adult cases have been reported. Severe stenosis at the level of the atlas may predispose individuals to severe spinal cord contusion, as occurred in our patient after sustaining trivial trauma.- - - - - - - - - - ranking = 70.101494241373keywords = spinal canal, canal (Clic here for more details about this article) |
3/33. Sudden onset of cervical spondylotic myelopathy during sleep: a case report.Cervical spondylotic myelopathy is a common cause of compressive spinal cord dysfunction. The typical course involves either a gradual or an episodic increase in symptoms and neurologic deficits, with impairment evolving over a period of months to years. Acute neurologic deterioration in conjunction with cervical spondylosis has been described almost exclusively in traumatic situations such as disk herniation. We report a case of an acute, nontraumatic onset of tetraplegia in association with cervical spondylosis. A 56-year-old man developed tetraplegia during a 1-hour nap, with loss of volitional control of his extremities, impaired sensation below the C3 dermatome, and increased muscle tone. magnetic resonance imaging of the cervical spine revealed canal stenosis and increased T2 signal within the cord. This case report describes the rehabilitation course for this patient and reviews the clinical spectrum of onset and progression of cervical spondylotic myelopathy.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |

5/33. Tetraplegia after coronary artery bypass grafting.The authors present a rare case of a cervical cord dysfunction after uncomplicated coronary artery bypass grafting. The preoperative neurological examination did not reveal any abnormalities; however, the postoperative magnetic resonance image showed significant spinal canal stenosis at the same levels as high signal lesions. Although the pathophysiological basis of the case was impossible to determine retrospectively, it seems probable that placing the neck in an extended position during surgery might have aggravated a preexisting spinal canal stenosis to produce cervical injury. IMPLICATIONS: The authors present a rare case of tetraplegia after coronary artery bypass grafting. It is suggested that neck extension during surgery might have aggravated an occult preexisting cervical spinal canal stenosis to produce cervical injury.- - - - - - - - - - ranking = 207.30448272412keywords = spinal canal, canal (Clic here for more details about this article) |
6/33. Tetraparesis due to exostotic osteochondroma at upper cervical cord in a patient with multiple exostoses-mental retardation syndrome (langer-giedion syndrome).STUDY DESIGN: Case report of a severe upper cervical cord compression and tetraparesis by a massive cervical exostotic osteochondroma in a patient with multiple exostoses-mental retardation syndrome (langer-giedion syndrome; LGS). OBJECTIVE: To describe this very rare pathological condition and the results of surgical intervention. SETTING: Gifu, japan. methods: A 23-year-old man was referred to our clinic because of progressing tetraparesis. He had previously been diagnosed with hereditary multiple exostoses and mental retardation. As he had not complained of any symptoms, his family only noticed the tetraparesis after advanced deterioration. His face possessed the pathognomic features of LGS. A postmyelogram CT scan demonstrated an exostotic mass arising from the left-side C2 pedicle with associated severe spinal cord compression. He was diagnosed with LGS. Hemilaminectomy on the left side and resection of the osteochondroma were performed. RESULTS: At 5 years postoperatively, a neurological examination showed the full return of all motor functions. The CT scan revealed no intracanalar recurrence of the tumor. CONCLUSION: In this case of severe tetraparesis due to cervical osteochondroma, decompression by hemilaminectomy provided excellent results. In patients with LGS and intracanalar osteochondroma, the neurological deficit may be masked by mental retardation. Hence, awareness of this pathological condition will help clinicians diagnose it at an early stage.- - - - - - - - - - ranking = 2keywords = canal (Clic here for more details about this article) |
7/33. Complete recovery of severe quadriparesis caused by stab wound at the craniocervical junction.Non-missile penetrating spinal cord injuries are uncommon, and involvement of the craniocervical junction is even less frequent. The author reports a case of 42-year-old male who presented with quadriparesis immediately following stab injury inflicted with a kitchen knife to the back of his neck. The knife was retained in the patient's neck. Neurological examination revealed spastic paraplegia and severe weakness of the left upper limb and the right-hand grip, and sensory disturbance from C2 and downwards. In addition to these symptoms, cerebrospinal fluid (CSF) was leaking from the wound. Computerised tomography (CT) scan showed the blade passed through the spinal canal and its tip reached the odontoid peg. After retrieval of the knife, his quadriparesis recovered. The management and outcome of the patient are described.- - - - - - - - - - ranking = 69.101494241373keywords = spinal canal, canal (Clic here for more details about this article) |
8/33. Sudden quadriplegia after acute cervical disc herniation.BACKGROUND: Acute neurological deterioration secondary to cervical disc herniation not related to external trauma is very rare, with only six published reports to date. In most cases, acute symptoms were due to progression of disc herniation in the presence of pre-existing spinal canal stenosis. CASE REPORT: A 42-year-old man developed weakness and numbness in his arms and legs immediately following a sneeze. On physical examination he had upper motor neuron signs that progressed over a few hours to a complete C5 quadriplegia. An emergent magnetic resonance imaging study revealed a massive C4/5 disc herniation. He underwent emergency anterior cervical discectomy and fusion. Postoperatively, the patient remained quadriplegic. Eighteen days later, while receiving rehabilitation therapy, he expired secondary to a pulmonary embolus. autopsy confirmed complete surgical decompression of the spinal cord. CONCLUSIONS: Our case demonstrates that acute quadriplegia secondary to cervical disc herniation may occur without a history of myelopathy or spinal canal stenosis after an event as benign as a sneeze.- - - - - - - - - - ranking = 138.20298848275keywords = spinal canal, canal (Clic here for more details about this article) |
9/33. Advanced Chiari malformation type I with marked spinal cord atrophy. Case report.The authors discuss the results obtained in patients who underwent foramen magnum decompression for longstanding advanced Chiari I malformation in which marked spinal cord atrophy was present. This 50-year-old woman presented with progressive quadriparesis and sensory disorders. magnetic resonance imaging revealed the descent of cerebellar tonsils and medulla associated with remarkable C1-L2 spinal cord atrophy. After a C-1 laminectomy-based foramen magnum decompression, arachnoid dissection and duraplasty were undertaken. These procedures resulted in remarkable neurological improvement, even after 40 years of clinical progression. Spinal cord atrophy may be caused by chronic pressure of entrapped cerebrospinal fluid in the spinal canal.- - - - - - - - - - ranking = 69.101494241373keywords = spinal canal, canal (Clic here for more details about this article) |
10/33. Epidural varix at the cervicothoracic junction: unusual cause of quadriplegia: a case report.STUDY DESIGN: A case report describing an unusual incident of quadriplegia in a young adult male caused by an epidural varix at the cervicothoracic junction. OBJECTIVE: To report an unusual case of quadriplegia caused by an epidural varix at the cervicothoracic junction. SUMMARY OF BACKGROUND DATA: Epidural varices are dilated tortuous elongated veins inside the central canal. In degenerative spinal stenosis, these varices are a result of venous stagnation and contribute to the pathogenesis of radicular pain. In the absence of stenosis, primary varicosities develop as a result of dynamic obstruction to venous outflow during spinal movements. A primary epidural varix can produce neurologic deficit similar to a space occupying lesion within the spinal canal. The myeloradiculopathy is of a slow progressive nature. MATERIAL AND methods: A young man presented with an acute onset flaccid quadriplegia in the absence of significant trauma. magnetic resonance imaging revealed an extradural space occupying lesion at the cervicothoracic junction that was diagnosed as an isolated epidural varix during surgery. RESULTS: No neurologic recovery occurred. Postoperative magnetic resonance imaging revealed a syrinx in the cervicothoracic cord. CONCLUSION: In the absence of other precipitating factors, the cord injury was attributed to the epidural varix. A temporary impedance to the venous outflow with the increase in the venous pressure has been hypothesized as the mechanism of cord injury.- - - - - - - - - - ranking = 70.101494241373keywords = spinal canal, canal (Clic here for more details about this article) |
