Extramedullary hematopoiesis (EMH) is occasionally reported in idiopathic myelofibrosis and is generally found in the liver, spleen, and lymph nodes several years after diagnosis. Myelofibrosis presenting as spinal cord compression, resulting from EMH tissue is very rare. A 39-yr-old man presented with back pain, subjective weakness and numbness in both legs. Sagittal magnetic resonance imaging showed multiple anterior epidural mass extending from L4 to S1 with compression of cauda equina and nerve root. The patient underwent gross total removal of the mass via L4, 5, and S1 laminectomy. Histological analysis showed islands of myelopoietic cells surrounded by fatty tissue, consistent with EMH, and bone marrow biopsy performed after surgery revealed hypercellular marrow and megakaryocytic hyperplasia and focal fibrosis. The final diagnosis was chronic idiopathic myelofibrosis leading to EMH in the lumbar spinal canal. Since there were no abnormal hematological findings except mild myelofibrosis, additional treatment such as radiothepary was not administered postoperatively for fear of radiotoxicity. On 6 month follow- up examination, the patient remained clinically stable without recurrence. This is the first case of chronic idiopathic myelofibrosis due to EMH tissue in the lumbar spinal canal in Korea.

3.Expert consensus on clinical diagnosis and treatment of bone metastases and bone-related diseases of prostate cancer (2021 edition).
Chinese Journal of Oncology 2021;43(10):1016-1026
The morbidity and mortality of prostate cancer ascend yearly, which seriously threatens the health of the male population. Bone is the main metastasis site of prostate cancer, with bone metastases and skeletal-related events (SREs) occuring in more than 70% of patients with advanced prostate cancer. Bone metastases and the resulting SREs, such as spinal cord compression and pathological fracture, seriously affect the life quality of the patients. Although the active treatments of the primary disease is important, the application of bone-modifying agents to prevent SREs cannot be overlooked. However, there is no standard treatment procedure for the bone metastasis of prostate cancer at present. According to the clinical status, the Genitourinary Oncology Committee of Chinese Anti-cancer Association formulated this consensus, which integrated clinical evidence and real world clinical practices in China and abroad, to help clinicians make more accurate diagnosis and treatment for the bone metastases of prostate cancer with multidisciplinary strategies.

A case is presented of acute spinal cord compression by a thoracic dumbbell spinal schwannoma in a young woman with neurofibromatosis type 1 (NF-1). A successful outcome was achieved with total excision of the lesion and decompression of the spinal cord. Greater recognition of the reversibility of spinal cord compression in the developing world is necessary to reduce major permanent morbidity.

A model that provides reproducible, submaximal yet sufficient spinal cord injury is needed to allow experiments leading to development of therapeutic techniques and prediction of clinical outcome to be conducted. This study describes an experimental model for spinal cord injury that uses three different volumes of balloon inflation and durations of compression to create a controlled gradation outcome in adult dogs. Twenty-seven mongrel dogs were used for this study. A 3-french embolectomy catheter was inserted into the epidural space through a left hemilaminectomy hole at the L4 vertebral arch. Balloons were then inflated with 50, 100, or 150 microliter of a contrast agent at the L1 level for 6, 12, or 24 h and spinal canal occlusion (SCO) measured using computed tomography. Olby score was used to evaluate the extent of spinal cord injury and a histopathologic examination was conducted 1 week after surgery. The SCO of the 50, 100, and 150 microliter inflations was 22-46%, 51-70%, and 75-89%, respectively (p < 0.05). Olby scores were diminished significantly by a combination of the level of SCO and duration of inflation in all groups. Olby scores in the groups of 150 microliter-12 h, 150 microliter-24 h, and 100 microliter-24 h were 0.5, 0, and 1.7, respectively. Based on these results, a SCO > 50% for 24 h, and > 75% for 12 h induces paraplegia up to a week after spinal cord injury.

OBJECTIVETo explore the relationship of motor dysfunction of the lower extremities with the imaging appearances and clinical features of metastatic epidural spinal cord compression (MESCCs).
METHODSFrom July 2006 to December 2007, 26 successive patients with metastases of the thoracic, lumbar and the cervical spine were treated in our department. Forty-three main involved vertebra in all 26 patients were evaluated by magnetic resonance imaging and computed tomography, and were scored according motor dysfunction in this study. Fourteen patients (25 vertebrae) had motor dysfunction.
RESULTSAmong 26 patients, 12 cases with visceral metastasis,in which had motor dysfunction in 10 cases; 14 cases without visceral metastasis, in which had motor dysfunction in 4 cases; comparison between two groups, P=0.0079. Among vertebral presence of continuity of 43 main involved vertebrae, 16 vertebrae had motor dysfunction;among vertebral absence of continuity, motor dysfunction occurred in 9 vertebrae, comparison between two groups, P=0.1034. Among vertebral presence of lamina involvement of 43 main involved vertebrae, 11 vertebrae had motor dysfunction; among vertebral absence of lamina involvement, motor dysfunction occurred in 14 vertebrae, comparison between two groups, P=0.020 5. Among vertebral presence of protruding of vertebral posterior wall of 43 main involved vertebrae, 12 vertebrae had motor dysfunction; among vertebral absence of protruding of vertebral posterior wall, 13 vertebrae had motor dysfunction, comparison between two groups, P=0.0334. Among vertebral presence of involvement epidural space of 43 main involved vertebrae, 11 vertebrae had motor dysfunction; among vertebral absence of involvement epidural space, 14 vertebrae had motor dysfunction, comparison between two groups, P=0.003 6. Such factors as age, gender, whether or not received regular chem before admission, back pain degree of metastasis, received regular chem before admission, therapeutic efficacy of primary tumor, number of bony metastases outside spine, number of the main involved vertebrae, level of vertebral metastases location, level of continuous involved vertebrae, vertebral-body involvement, fracture of anterior column, fracture of posterior wall, and pedicle involvement had no effects on incidence of motor dysfunction due to MESCC (P>0.05).
CONCLUSIONMESCC with visceral metastases, lamina involvement, presence of outstanding buttocks sign of posterior wall,involvement epidural space tended to cause symptomatic MESCC. Incidence of continuity of main involved vertebrae occurred more frequently in the CUTS compared with other levels of spine.

OBJECTIVETo analyze the correlations between increased spinal cord signal intensity on magnetic resonance images (MRI) and the clinical prognosis of compressive cervical myelopathy.
METHODSSixty-six patients with cervical spondylotic myelopathy underwent surgeries through the anterior approach. In all the patients, the diagnoses were established on the basis of both neurological examination and MRI findings that showed spinal cord compression. The patients were divided into two groups according to preoperative MRI, namely isointense MRI T1/T2 signal group and iso/hyperintense MRI T1/T2 group. The JOA scores of the patients were evaluated before and at 6 and 12 months after the operation.
RESULTSThe patients were followed up for 12 to 38 months after the operation (mean 21 months), and no statistically significant difference were found in the pre- and postoperative JOA scores between the two groups (P>0.05).
CONCLUSIONThe peoperative hyperintense signals on T2 weighted MRI does not correlate to the prognosis of patients with compressive cervical myelopathy, who may also have favorable clinical outcomes after the operation.

OBJECTIVE:
To evaluate the therapeutical effect of surgical treatment for thoracic angioma with extraosseous extension which causes spinal cord compression and neurological dysfunction.
METHODS:
We retrospectively analyzed 5 cases of thoracic vertebral body angioma with extraosseous extension and spinal cord compression. The operation were performed through anterior approach to resect the involved vertebral body and intracanal angioma in 5 patients. Bone graft and internal fixation were also completed in the meantime. Two patients accepted radiotherapy for 2 periods of treatment postoperatively, and the other 3 patients didn't accept the other supportive therapy.
RESULTS:
The blood loss during the operation was 1000 mL to 1500 mL. All the patients recovered their neurological function rapidly after the operation. The patients were followed up for 1 to 4 years, and no patient recurred. The bone graft was solidly fused in all patients. No hardware failure occurred.
CONCLUSION
The surgical treatment for thoracic vertebral body and extraosseous angioma with spinal cord compression is effective, reliable, and workable. Good long-term result can be obtained.

Yonsei Medical Journal 2004;45(3):539-542
The authors describe a case of an 80-year-old man with a gradual weakness of the lower extremities not linked to any known traumatic episode over the 2 weeks before admission. CT scan and MRI of the spine revealed a cystic formation, measuring about 1cm in diameter, at C7-T1 at the left posterolateral site at the level of the articular facet. During surgery, the mass appeared to be in the ligamentum flavum at the level of the articular facet and was in contact with the dura mater. After the removal of the mass, there was an immediate and significant improvement of the patient's symptoms. Histopathologic examination showed the cyst to be composed of nonspecific degenerative fibrous tissue with mild inflammatory change and confirmed the cyst as a synovial cyst. Synovial cyst in the cervical region is a very rare lesion causing myelopathy. Surgical removal of the cyst and decompression of the spinal cord results in good neurological recovery.
