While syringomyelia is not a rare spinal disorder, syringomyelia associated with a spinal arachnoid cyst is very unusual. Here, we report a 62-year-old man who suffered from gait disturbance and numbness of bilateral lower extremities. Spinal magnetic resonance imaging (MRI) showed the presence of a spinal arachnoid cyst between the 7th cervical and 3rd thoracic vertebral segment and syringomyelia extending between the 6th cervical and 1st thoracic vertebral segment. The cyst had compressed the spinal cord anteriorly. Syringomyelia usually results from lesions that partially obstruct cerebrospinal fluid flow. Therefore, we concluded that the spinal arachnoid cyst was causing the syringomyelia. After simple excision of the arachnoid cyst, the symptoms were relieved. A follow-up MRI demonstrated that the syringomyelia had significantly decreased in size after removal of the arachnoid cyst. This report presents an unusual case of gait disturbance caused by syringomyelia associated with a spinal arachnoid cyst.

Spinal cord infarction is becoming recognized as an important cause of acute myelopathy in cats. Although the definitive diagnosis is confirmed through postmortem histopathologic examination, MR imaging features provide valuable informations for the diagnosis of spinal cord infarction. The aim of this report is to describe MR findings of acute spinal cord infarction in two cats and to evaluate usefulness of low field MRI (0.3Tesla) as a potential diagnostic tool of acute spinal cord infarction. A cat (unknown age, neutered male mixed breed cat) was referred one day after the acute onset of non-ambulatory spastic tetraparesis and the other cat (a 9-year-old, neutered female domestic short hair cat) was presented due to the acute onset of non-ambulatory paraparesis and one day later paraplegia. The lesions of the MR images were shown on the spinal cord parenchyma over C2 to C6 in case 1 and L2 to L5 in case 2. The MR images in these two cases were characterized by focal intramedullary lesions, mainly involving grey matter which were hyperintense T2 weighted and FLAIR images and hyperintense on DWI and hypointense on ADC map. The MR findings in both cases were highly suggestive of acute spinal cord infarctions, based upon previous reported small animal cases and human cases. In conclusion, based on MR features, together with the history and clinical examination findings, MRI modality can be used as an antemortem tool for the diagnosis of acute spinal cord infarction in cats.

The incidence of diastematomyelia associated with teratoma is extremely rare. We present a case of sacrococcygeal teratoma in a neonate with split spinal cord malformation[SSCM]. Magnetic resonance imaging[MRI] showed a heterogenous mass lesion with cyst in the sacrococcygeal region and multiple spinal anormalies [diastematomyelia, tethered cord, hydromyelia, and hemivertebrae]. The mature teratoma was confirmed on histopathological examination. In SSCMs, the potential for coexisting congenital anomalies at separate levels of the spinal cord must be considered in radiological investigations.

Neurosyphilis is an infection of the brain or spinal cord that is caused by the bacterium Treponema pallidum. Syphilitic myelitis, which involves the spinal cord, is a very rare form of neurosyphilis seen in patients with syphilis. It requires differentiation from other diseases of the spinal cord, including idiopathic transverse myelitis and spinal cord infarction. Herein, we describe the presentation and diagnosis of syphilitic myelitis in a 43-year-old woman, based on a flip-flop sign and candle guttering appearance depicted in magnetic resonance imaging and laboratory tests.

Spinal cord lipomas are commonly associated with spinal dysraphism. The lipomas without spinal dysraphism have been reported to be only 1% of all spinal cord lipomas. We report two cases of patients with spinal intramedullary lipomas without dysraphism. One patient was a 57-year-old man who had lower back pain and right-sided sciatica for 20 years. Magnetic resonance imaging (MRI) of the spine demonstrated an intradural mass occupying L1 to L2. The other patient was a 27-year-old woman who had back pain and gait disturbance for 5 months. MRI of the spine showed an elongated intradural mass occupying T7 to T9. Total laminectomy with partial resection of the lesions was performed on both patients. Pathological studies confirmed the diagnosis of spinal cord lipoma. They exhibited no dysraphism. Postoperatively, neurological symptoms improved in both patients.

A 29-year-old woman had 1-month history of back pain radiating into lower extremities, motor weakness, and sensory abnormalities in both lower extremities. Contrast-enhanced spinal magnetic resonance imaging (MRI) revealed a homogeneously enhancing mass at the T12~L1 and several intradural enhancing nodular lesions at L2~S1. Tumor resection surgery was performed and following histological examination showed that the tumor satisfied the diagnostic criteria for atypical choroid plexus papilloma (CPP). To find primary tumor sites, contrast-enhanced brain MRI, whole spine MRI, and PET-CT were carried out and additional lesions were detected at the fourth ventricle, right cerebellum, and upper thoracic spinal cord. This is a very rare case of metastatic atypical CPP that involves brain, upper thoracic spinal cord, and cauda equina with initial manifestation of radicular symptoms without clinical signs of primary brain lesion.

The Cervical spondylotic myelopathy (CSM) is degenerative compressive myelopathy which initiation of symptoms seems to be induced by minor cervical trauma or spontaneous event. There was a case of Claim medical examination which was requested to discriminate the cause of ambulatory quadriparesis. Patient asserted that the onset of his myelopathy was followed by minor trauma. The author considered the medical recordings, MRI scan, Claim reports by claim manager. The space available for cord was the smallest at C3-4 level. But on MRI findings, the spinal cord at C3-4 level seemed to be already damaged. There were no recent injury evidences such as hemorrhages, spinal cord contusions, edema, soft tissue hemorrhages. If the space available for cord was small enough to compress the spinal cord, the serious neurologic deficits, non-ambulatory quadriplegia, etc were commonly induced by cervical extension trauma. Patient's asserts did not correspond to his clinical course after cervical trauma. The author reports a case of medical examination for the relationship between symptom onset of cervical spondylotic myelopathy and minor trauma within author's experience.

Purpose : Cervical spondylotic myelopathy is a varied clinical syndromes and the most serious condition of cervical spondylosis. Spinal cord dysfunction is often caused by the compression on spinal cord. The purpose of this report was to describe physical examination and the process of disorders on cervical spondylotic myelopathy(CSM). Methods : Three cases with cervical myelopathy were presented with magnetic resonance image(MRI), Nurick's grade and Japanese Orthopaedic Association(JOA) score. Results : This studies showed a variable clinical course with gradual neurological deterioration in two cases. but one case was improved by operation and a regular aerobic exercise. MRI, Nurick's grade, JOA score are a useful adjunct for CSM evaluation. Conclusion : The state of CSM is variable, which may affect conservative treatments and surgery. It is needed to be a carefull approach and studies for a conservative treatment and management on CSM.

Cavernous angiomas are being increasingly well recognized throughout the central nervous system due to the widespread use of magnetic resonance imaging(MRI). However, these malformations are uncommon in the spinal column and rarely occur in the spinal cord. Here, we report a case of a cervical cord intramedullary cavernous angioma in a 49-year-old man. The patient had complained of left upper extremity paresthesia and weakness in the left hand for 5 days prior to admission. A neurological examination showed a left C-6 dermatome paresthesia and a weakness in the left hand grasping power. A MRI demonstrated a mixed signal intensity core at the C-5 level and a surrounding edema on the T-2 weighted image. Conservatively, a laminectomy was performed and slightly hard and well demarcated intramedullary mass was removed. A histological examination confirmed the diagnosis of a cavernous angioma.
