The data on the normal measurement of spinal cord are essential for an objective assessment of equivocal change of spinal cord size in the various clinical settings. The present study was therefore undertaken to evalua-te normal range of spinal cord dimensions in Korans. CT myelography of the cervcal and thoracic region was performed in 60 patients who had symptoms referable to lumbosacral region and then computed tomographic measurement of spinal cord and dural sac was performed. The results are as follows: 1. The anteroposterior diameter of spinal cord was maximum, at C1 level(8.6 $\pm$1.4mm) and minimum at T6 level (6.4$\pm$1.7mm), 2. the transverse diameter of spinal cord was maximum at C4 and C5 levels (13.3$\pm$1.6mm) and minimum at T8 (8.1$\pm$1.9mm) and T10 (8.1$\pm$1.3mm) levels. 3. The area of spinal cord was maximum at C5 level(76$\pm$16mm2) and minimum at T6 (40 $\pm$24mm2) and T8 (40$\pm$23mm2) levels. 5. The ratio of anteroposterior diameter of spinal cord/dural sac was maximum at C4 level (0.73$\pm$0.14)and minimum at T12 level(0.52$\pm$0.15). the ratio of transverse diameter of spinal cord/dural sac was maximum at C3(0.66$\pm$0.14) levels and minimum at T12 level;(0.29$\pm$0.20), 6. The locationof cervical cord in dural sac was mainly ventral (56%) at C1 level middle(40-73%) from C2 to C6 level and dorsal (44%) at C7 level. The location of thoracic cord in dural sac was chiefly middle(61%) at T2 level and lower thoracic level(T10 : 60% and T12: 51%) and mainly ventral (59-84%) at other levels.
A retrospective review of consecutive 35 patients'pre and post operative abdominal computed tomography was performed to determine frequency and degree of bile duct dilatation following Billroth Ⅱ operation for stomach cancer and it's clinical significance. Degree of intrahepatic biliary dilatation was classified as mild, moderate, marked according to the extension into central, middle and peripheral zone of liver, respectively. Three specialists on the abdominal image participated in analysis of those findings without prior information of the patients. Intrahepatic biliary dilatation was seen in 22 patients(63%) analysed by at least one radiologist, in 13 patients(37%) by at least two radiologists. Bile duct dilatation on CT was common finding and not necessarily meant tumor recurrence. Vagotomy and afferent loop resulted form Billroth Ⅱ were one of possible causes of bile duct dilatation. This study showed in the cases of bile duct dilatation without clinical and other radiological evidence of recurrence, no further study are needed and only enough to follow up study.
Purpose : To investigate the causes of gastric wall shortening in ealy gastric cancer, upper gastrointestinalstudy was correlated with pathologic findings. Materials and Methods : We evaluated 41 cases (m:F=1.7:1, averageage=49) of early gastric cancer, retrospectively. The gastric wall shortening were classified as Grade I;none,Grade II;intermediate, and Grade III; prominent. Pathologic findings such as size of lesions, depth of tumorinvasion, degree of the submucosal fibrosis, degree of thickness of the submucosa and muscularis propria, andmorphologic patterns of lesions including conversing mucosal folds were correlated with the degree of gastric wallshortening on upper gastrointestinal series. Results : Submucosal fibrosis was present in 4 cases in Grade I(n=21), 4 cases in Grade II (n=6) and 8 cases in Grade III (n=10), Positive conversing mucosal folds were seen in 5cases in Grade I (n=17), 0 case in Grade II (n=2) and 9 cases in Grade III (n=9), Gastric wall shortening wassignificantly associated with submucosal fibrosis and conversing mucosal folds of early gastric cancer. (p=.0001and p=.002, respectively) Conclusion : Upper gastrointestinal finding of gastric wall protrusion in patients withearly gastric cancer should not misinterprete as advanced gastric cancer sine the finding could be a result ofsubmucosal fibrosis.
Spontaneous pneumomediastnum is a very rare complication of systemic autoimmune diseases, The precise mechanism of pneumomediastinum in dermatomyositis is not well known. Pulmonary alveoli rupture secondary to interstitial pneumonitis or pulmonary infarctions consequent upon vasculitis are the suggested mechanisms, Among the idiopathic inflammatory myopathies, dermatomyositis and polymyositis show similar clinical manifestations except skin lesions. But pneumomediastinum occurs exclusively in cases with dermatomyositis, not in case with polymyositis. In a literature review, patients with dermatomyositis and pneumomediastinum had some characteristic features. As compared with dermatomyositis without pneumomediastinum, CK level was normal in about half and concomitance of interstitial lung disease and cutaneous vasculitis were very frequent. We experienced a case of dermatomyositis with spontaneous pneumomediastinum and subcutaneous emphysema, Thus we report that with a review of the literature and analysis of reported cases.
