This study was aimed to investigate the clinical features of multiple myeloma (MM) complicated by spinal infiltration (extramedullary plasmacytoma) so as to enhance the understanding of this kind of MM and reduce the missed diagnosis for these MM patients. 10 patients with MM complicated by spinal infiltration were enrolled in this study. Bone marrow, blood, hepatic and renal function, electrolyte, beta2 microglobulin, C-reactive protein and immunoglobulin (M-protein) were detected. The involved spinal sites were examined by using magnetic resonance imaging (MRI) or computerized tomography (CT). 10 patients were staged according to International Stage System (ISS) and Duric-Salmon stage system. The clinical data of patients were analyzed. The results showed that among 10 cases of MM complicated by spinal infiltration, involved pectoral cord was observed in 7 cases, involved lumbar cord in 2 cases and sacral cord in 1 case. The treatment with operation and protocol containing cisplatin, ifosfamide etoposide, prednisone, and bortezomib in combination with other drugs indicated that the total remission rate was 80% (8/10), no serious adverse responses was observed. In conclusion, the patients with MM complicated by spinal infiltration must be diagnosed and treated as early as possible. Once paraplegia happened in patients, the therapeutic efficacy and prognosis would be very poor.

Although cysticercosis is the most common parasitic disease affecting the central nervous system, spinal cysticercosis is rare. A rare form of spinal cysticercosis involving the whole spinal canal is presented. A 45-year-old Korean male had a history of intracranial cysticercosis and showed progressive paraparesis. Spinal magnetic resonance scan showed multiple cysts compressing the spinal cord from C1 to L1. Three different levels (C1-2, T1-3, and T11-L1) required operation. Histopathological examination confirmed cysticercosis. The patient improved markedly after surgery.

Appreciation of the normal variation of anterior and posterior diameter of the lumbar spinal canal under computerized axial tomogram may throw very important value on the diagnosis and treatment in lumbar spinal problems. The authers have measured the diameter of the lumbar spinal canal using EMI scanner CT 5005. The data was first based on the study of two cadaver lumbar spine and then the study of 268 normal Korean adults male 185, and female 83. The results were summerized as follows. 1. The diameter of the osseous segment was more narrow than articular segment in normal lumbar spinal canal, 2. The shape of lumbar spinal canal was oval in upper lumbar. but became triangular going down to the lower lumbar. There was no difference of diameter in sex. 4. The average diameter of anterior and posterior spinal canal was; L1 16.53± 0.18, L2 16.23± 0.215, L3 15.42± 0.26, L4 15.57± 0.43 and l% 17.7± 1.63mm respectively. 5. The average diameter of transverse spinal canal was; L1 23.31± 0.18, L2 23.76± 0.28, L3 24.78± 0.345, L4 26.07± 0.605 and L5 29.31± 1.19mm respectively. 6. It was more accurate to check out the pathology of the lumbar spinal canal using coinputerized axial tomogram than other method previously used.

Angiolipoma is a rare benign soft tissue tumor, an unusual variant of lipoma,consisting of fatty and vascular components and located in the subcutis, usually in the trunk and extremities. We report a case of posterior mediastinal angiolipo-ma extending into the spinal canal and showing both fat and angiomatous fea-tures on CT scan.

STUDY DESIGN: Retrospective study. PURPOSE: To analyze the incidence and prevalence of clinical adjacent segment pathology (CASP) following anterior decompression and fusion with cage and plate augmentation for degenerative cervical diseases. OVERVIEW OF LITERATURE: No long-term data on the use of cage and plate augmentation have been reported. METHODS: The study population consisted of 231 patients who underwent anterior cervical discectomy and fusion (ACDF) with cage and plate for degenerative cervical spinal disease. The incidence and prevalence of CASP was determined by using the Kaplan-Meier survival analysis. To analyze the factors that influence CASP, data on preoperative and postoperative sagittal alignment, spinal canal diameter, the distance between the plate and adjacent disc, extent of fusion level, and the presence or absence of adjacent segment degenerative changes by imaging studies were evaluated. RESULTS: CASP occurred in 15 of the cases, of which 9 required additional surgery. At 8-year follow-up, the average yearly incidence was 1.1%. The rate of disease-free survival based on Kaplan-Meier survival analysis was 93.6% at 5 years and 90.2% at 8 years. No statistically significant differences in CASP incidence based on radiological analysis were observed. Significantly high incidence of CASP was observed in the presence of increased adjacent segment degenerative changes (p<0.001). CONCLUSIONS: ACDF with cage and plate for the treatment of degenerative cervical disease is associated with a lower incidence in CSAP by 1.1% per year, and the extent of preoperative adjacent segment degenerative changes has been shown as a risk factor for CASP.

OBJECTIVETo confirm diagnosis of a special case with chief complaints of abdominal pain and dyskinesia of lower extremities.

METHODSThe clinical symptoms, signs, MRI, pathological findings and the results of blood test for microfilaria were analyzed.

RESULTSThe patient was a 6-year old girl who had abdominal pain for 10 days dyskinesia of lower extremities for 6 days accompanied by difficulty in urination and defecation. There was tenderness on T7-9 spinous process, sensory dullness below the umbilicus. Babinski's and Oppenheim's sign were bilaterally positive, and ankle clonus was positive. MRI showed space occupying change in the vertebral canal at T7-9 level. The mass of 2 cm x 1 cm x 1 cm size was removed by surgical operation and histopathological study showed obvious fibrous tissue proliferation accompanied by eosinophil, lymphocyte and neutrophil infiltration around a worm-like structure. Night time blood test performed at 23:00 confirmed the presence of microfilaria.

CONCLUSIONThe diagnosis of filariae in vertebral canal could be confirmed.

Terminal myelocystocele is a rare form of occult spinal dysraphism in which the hydromyelic caudal spinal cord and the subarachnoid space are hemiated through a posterior spina bifida. A 1.5 month old boy presented with a large lumbosacral mass and urinary incontinence. The magnetic resonance imaging, operative findings and pathological findings revealed a low lying conus with a dilated central canal dorsally attached to the subcutaneous tissue. Ventral subarachnoid space was enlarged and herniated through the laminar defect of the sacrum. The lesion was typical of a terminal myelocystocele. The clinical features are different from those of myelomeningocele in many aspects. Though the incidence is low, terminal myelocystocele should be included in the differential diagnosis of congenital lesions presenting as a lumbosacral mass.
