We report an extremely rare case of traumatic cervical spinal subdural hematoma not related to intracranial injury. There has been no report on traumatic cervical spinal subdrual hematoma not related to intracranial injury. A 27-year-old female patient was admitted to our emergency room due to severe neck pain and right arm motor weakness after car collision. On admission, she presented with complete monoplegia and hypoesthesia of right arm. Magnetic resonance imaging (MRI) revealed subdural hematoma compressing spinal cord. Lumbar cerebrospinal fluid (CSF) analysis revealed 210,000 red blood cells/$mm^3$. She was managed conservatively by administrations of steroid pulse therapy and CSF drainage. Her muscle power of right arm improved to a Grade III 16 days after admission. Follow-up MRI taken 16th days after admission revealed almost complete resolution of the hematoma. Here, the authors report a traumatic cervical spinal SDH not associated with intracranial injury.

Objective : Thoracic ossification of the ligamentum flavum (OLF) is a relatively rare disease. Because of ambiguous clinical symptom, it is difficult for early diagnosis of OLF and subsequent treatment can be delayed or missed. Therefore, the purpose of this study is to comprehensively assess the prevalence and distribution of thoracic OLF by magnetic resonance imaging (MRI) and coexisting spinal disease in Korean patients with back pain or leg pain. Methods : The sample included 2134 Korean patients who underwent MRI evaluation for back pain. The prevalence and distribution of thoracic OLF were assessed using lumbar MRI with whole spine sagittal images. Additionally, we examined the presence of coexisting lumbar and cervical diseases. The presence of thoracic OLF as well as clinical parameters such as age, sex, and surgery were retrospectively reviewed. Results : The prevalence of thoracic OLF in total patients was 16.9% (360/2134). The prevalence tended to increase with aging and was higher in women than in men. The lower thoracic segment of T10-11 was the most frequently affected segment. Of the 360 patients with OLF, 31.9% had coexisting herniated thoracic discs at the same level. Approximately 74% of the patients with OLF had coexisting lumbar and cervical disease. Nine (2.5%) of 360 OLF patients underwent surgery for thoracic lesion. Conclusion : The prevalenceof thoracic OLF was relatively higher than those of previous reports. And coexisting lumbar and cervical disease were very frequent. Therefore, we should check coexisting spinal diseases and the exact diagnostic localization of ossification besides lumbar disease.

폐결핵을 치료하는 중 갑작스럽게 생긴 하지의 근력저하와 배뇨장애를 호소하는 환자에서, MRI를 이용하여 척수내 결핵종이 진단되었다. 항결핵 제재와 대량의 스테로이드를 5일간 사용한 후 신경학적 증상은 호전되어 결핵치료를 지속하던 중 20일째 전신경련이 발생하여 다발성 뇌결핵종이 동반되어 있음이 MRI상에 나타났다. 이후 내과적 치료만으로 방사선 소견과 임상증상이 호전되어 가고 있어 9개월째 있는 증례이다. 우리나라는 결핵의 유병률이 높고 다제약제내성결핵이 늘고 있어, 신경학적 증상을 호소하는 환자에서는 반드시 중추신경계 결핵을 염두에 두고 MRI를 시행하면 중추신경계 결핵종의 발견율이 높아질 것으로 사료되어 이에 보고하는 바이다.

A 3.5kg, 3-year-old castrated male Japanese domestic cat withpelvic limb ataxia and dysuria was referred to the Veterinary Medical Center of the Tokyo University. On the neurologic examination findings, both pelivic had a LMN paresis. The cat was FeLV positive and FIV negative. Radiographic findings did not identify the spinal lesions. In magnetic resonance images(MRI) of the lumbar spinal cord, the cat had the lesions in the lumbar(L) 1 and L3, characterized by hyperintensity on a transverse T2-weighted and T1-weighted images, and contrast enhancement was evident. The mass removed by dorsal laminectomy. Histopathological examination of the mass revealed spinal lymphoma. Three weeks after the surgery, the cat administered chemotherapy protocol for lymphoma by current protocol. Two weeks after chemotherapy, the cat had a metastasis to bone marrow and died.

Magnetic resonance imaging (MRI) is a standard imaging modality for diagnosing spinal stenosis, which is a common degenerative disorder in the elderly population. Standardized interpretation of spinal MRI for diagnosing and grading the severity of spinal stenosis is necessary to ensure correct communication with clinicians and to conduct clinical research. In this review, we revisit the Lee grading system for central canal and neural foraminal stenosis of the cervical and lumbar spine, which are based on the pathophysiology and radiologic findings of spinal stenosis.

Objective : To evaluate whether an early bone marrow edema pattern predicts vertebral deformity types and prognosis in osteoporotic vertebral compression fracture (OVCF). Methods : This retrospective study enrolled 64 patients with 75 acute OVCFs who underwent early MRI and followed up MRI. On early MRI, the low SI pattern of OVCF on T1WI were assessed and classified into 3 types (diffuse, globular or patchy, band-like). On followed up MRI, the vertebral deformity types (anterior wedge, biconcave, crush), degree of vertebral body height loss, incidence of vertebral osteonecrosis and spinal stenosis were assessed for each vertebral fracture types. Results : According to the early bone marrow edema pattern on T1WI, 26 vertebrae were type 1, 14 vertebrae were type 2 and 35 vertebrae were type 3. On followed up MRI, the crush-type vertebral deformity was most frequent among the type 1 OVCFs, the biconcave-type vertebral deformity was most frequent among the type 2 OVCFs and the anterior wedge-type vertebral deformity was most frequent among the type 3 OVCFs (p<0.001). In addition, type 1 early bone marrow edema pattern of OVCF on T1WI were associated with higher incidence of severe degree vertebral body height loss, vertebral osteonecrosis and spinal stenosis on the follow up MRI. Conclusion : Early bone marrow edema pattern of OVCF on T1WI, significant correlated with vertebral deformity types on the follow up MRI. The severe degree of vertebral height loss, vertebral osteonecrosis, and spinal stenosis were more frequent in patients with diffuse low SI pattern.

본 연구는 골 전이암에 대한 치료에 통상적으로 이용되는 방사선치료 후 치료반응을 객관적으로 평가하는 데 필요한 새로운 영상진단 방법의 적용 가능성을 확인하기 위하여 시행되었다. 척추에 혈행성 전이를 일으킨 21명의 환자를 대상으로 방사선치료 전 후에 확산 강조 자기공명 영상을 시행한 10명의 환자에서 방사선치료 전 후에 골수 조직의 신호 강도의 변화가 현저하였으므로 기존의 진단방법인 단순 X-선 촬영, 방사성 동위원소 골 주사, 전산화 단층 촬영 및 스핀 에코 자기공명 영상진단을 보완할 수 있다는 가능성을 확인하였다. 그렇지만 대상 환자의 숫자가 적고 추적기간이 짧기 때문에 이 촬영기법이 척추에 혈행성 골 정기가 의심되는 환자에서 기본적인 검사방법으로 자리잡기 위해서는 더 많은 화자를 대상으로 가능한 병리조직학적 검사를 병행하여 장기간에 걸쳐 전향적인 검토가 필요하다고 생각되었다.

Objective: This study was performed to report the changes in symptoms and radiological consequences of a patient diagnosed with spinal neurofibroma and complaining of lower back pain. Methods: The patient was diagnosed with a spinal neurofibroma after MRI examination and was treated with traditional Korean medicine, including traditional Korean medication and acupuncture. We measured the change in symptom severity using a numerical rating scale (NRS) and the Oswestry Disability Index (ODI). We also used the EQ-5D (EuroQoL-5D) scale to assess the patient's quality of life. In addition, we examined the change in the size of the cyst by MRI twice after discharge: at about 3 months after discharge and at about 8 months after discharge. Results: After about 6 weeks of treatment, most pathological symptoms had decreased. The patient showed a decline in NRS and ODI scores and showed an increase in quality of life. The two MRI examinations after the discharge revealed a decrease in the size of the cyst. Conclusions: Traditional Korean medicine can be a solution for patients with spinal neurofibroma causing neurological pain.

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.
