The significance of measurement of the spinal canal size was well recognized in case of detection of intraspinal tumor as well as diagnosis of spinal stenosis. The measurement of sagittal diameter of the lumber spinal canal by plain x-ray film is not always easy. However, the new method designed by Eisenstein made the measurement of sagittal diameter of the lumber spinal canal by plain x-ray film very easy. In order to study the range of normal values of the sagittal diameter of lumber spinal canal in Korean adults, authors measured antero-posterior and transverse diameter of the lumbar spinal canal in 290 normal Korean adults by Eisensteins method. The results obtained are as follows: 1. Mean values of sagittal diameter of the normal Korean adults male was 17.37±1.05mm at Ll, 16.43±1.12mm at L2, 15.89±1.20mm at L3, 15.45±1.24mm at L4, and 17.34±1.13mm at L5 vertebra and in female, 17.41±1.23mm at Ll, 16.45±1.20mm at L2, 16.14±1.41mm at L3, 15.40±1.32mm at L4, and 17.25±1.20mm at L5 vertebra. 2. Mean values of transverse diameter of the normal Korean adults male was 23.54±1.18mm at Ll, 24.61±1.17mm at L2, 25.78±1.41mm at L3, 27.72±1.86mm at L4, and 30.42±2.23mm at L5 vertebra and in female, 23.06±1.45mm at Ll, 23.90±1.48mm at L2, 25.21±1.53mm at L3, 26.62±1.88mm at L4, and 29.70±2.41mm at L5 vertebra. 3. In transverse diameter, it was increased more and more to the lower lumber level, the widest at L5 vertebra. 4. In sagittal diameter, it was decreased less and less to the lower lumbar level, the narrowest at L4, and increased again at L5 vertebra. 5. The difference of sagittal and transverse diameter of lumbar spinal canal at each level of lumbar spine was very significant statistically. 6. The difference of the transverse diameter of the lumber spinal canal between male and female was significant statistically but that of the sagittal diameter was not. 7. The difference of the sagittal and transverse diameter between each age group was not significant statistically.

MR images of seven patients with histologically documented synovial sarcoma were reviewed to find the suggestive or pathognomonic findings of the disease. MR appearance of the tumor was inhomogeneous, multiseptated mass with various degree of internal septation and infiltrative tumor margin. The signal intensity of the mass was slightly hyperintense relative to muscle on T1-weighted image and hyperintense relative to subcutaneous fatty tissue on T2-weighted image.

Percutaneous needle biopsy of pulmonary lesion with use of fluoroscopic guidance is well estabilished as a diagnostic tool but limited by the small size and inaccessibility of certain lesions. However, percutaneous needle biopsy'has been used increasingly in relation to advance and the salty of smaller biopsy needle and new imaging modalities such as ultrasound and CT. CT, because of its characteristics of high resolution, allows tissue sampling with considerable safty from area that heretofore could not be visualized under fluoroscopy. The authors summarized 44 pulmonary lesions that underwent CT-guided transthoracic biopsy with fine-needle over a 14 month period and analyzed the sensitivity of PTNB. -CT-guided PTNB was done with 20 gauge or 22 gauge Westcott biopoy needle (Mann medical products, USA). A diagnosis was made in 27 of 44 cases (61%) including malignany in 19 of 24 cases and benignancy in 8 of 20 cases. The pulmonary mass lesions were located at the peripheral zone of the lung field in 33 cases and at the central zone in 11 cases. Complications were observed in 2 cases which were pneumothorax and hemoptysis each but specific therapy was not required The sensitivity of PTNB by one session was 61% (27/44). The sensitivity of malignancy was 79% (19/24) and benignancy was 40% (8/20). These results suggest the usefulness of PTNB using fine needles be increased in eariler diagnosis and improved staging of pulmonary nodular lesions without significant complications.

An unconscious 5-year-old girl was admitted to the Intensive Care Unit. She was neglected by her parents; she suffered from inadequate nutritional, medical and emotional care. The girl appeared to be emotionally detached, dehydrated and malnourished; she had edematous extremities, moderately bruised skin and brittle coarse hair. Laboratory testing showed electrolyte imbalance, anemia, pneumonia, copper deficiency, and liver dysfunction in addition to severe protein-energy malnutrition (PEM). Medical intervention was followed by improvement of most of the symptoms. During the rehabilitation phase, the patient showed a voracious appetite and gained weight too fast. The liver became enlarged and the patient developed a mild fever due to excessive nutrition. The microcytic anemia with severe PEM did not responded to iron supplementation possibly due to the copper deficiency. Addition of copper without zinc and iron helped to improve the anemia. The patient was discharged to a childcare center where she received cognitive and psychosocial therapy.

Choriocarcinoma associated with a normal pregnancy is rare. Futhermore, choriocarcinoma coexistent with a viable pregnancy is even rarer and associated with a greater risk of hepatic and cerebral involvement. So timely diagnosis of the disease is important for successful treatment and aggressive diagnostic procedures may therefore warranted. The patient should be treated with primary intensive combination chemotherapy(EMA-CO) and the selective use of irradiation and surgical therapy. We experienced a case of metastatic choriocarcinoma of lung and kidney following preterm delivery at 34th week of pregnancy and so present it with brief review of literature.

A total of 213 fine needle aspirations from pulmonary lesions in 193 patients performed from January, 1986 to March, 1989 were analyzed. The cytologic diagnoses were unsatisfactory in 10, negative in 60, atypical in 6, suspicious in 11 and malignant in 126 cases. The cytologic types of the malignant cases were 47 squamous cell carcinomas, 40 adenocarcinomas, 10 small cell carcinomas, 6 large cell carcinomas and 10 metastatic tumors. They were verified by the histologic confirmation in 31 cases and by the clinical data in the remainder. There were 5 false-negative cases and none was false-positive, representing 96% sensitivity and 100% specificity. Primary lung cancers were accurately typed in 73% of histologically confirmed case. Cell blocks, prepared in 99 cases, were helpful in tumor typing of 11 cases.

Primary malignant laryngeal lymphoma is rare. In this case, diffuse wall thickening of the vocal cord and infraglottic larynx was seen on initial CT scan. After chemotherapy, follow-up CT neck scans showed a marked decrease of diffuse wall thickening of the vocal cord and infraglottic larynx ; diffuse laryngeal wall thickening is, however, a nonspecific finding which can be seen in other disease processes. If clinical evidence of infection and inflammation or remarkable change after antibiotics treatment is not definite, biopsy should be performed to rule out laryngeal lymphoma.

The abdominal tumors in children are different from those of adult. These tumors are the third most common one, preceded by leukemia and brain tumors, in children under 15 years. X-ray examination is the most important method among diagnostic approaches. The role of diagnostic imaging is to identify the precise anatomic location and extent of pathologic process with the minimal number of imaging procedures. 23 cases of abdominal tumors were reviewed in respect of age incidence, site of origin, radiologic findings. The results are briefly summarized as follows: 1. Neuroblastoma was the most common (6 cases) and wilm's tumor (5 cases), choledocal cyst (4 cases), ovarian mass (3 cases), hydronephrosis (2 cases), were descending order in frequency. 2. The most common site was retroperitoneum (60%) Kidney was the single most common site of origin. 3. Radiologic findings. The most common findings of plain radiography was ill defined soft tissue mass and this method was helpful in the presence of calcification especially in neuroblastoma. Ultrasonographic pattern was anechoic (cystic), echoic or mixed pattern, but this method provide less precise anatomical details, nevertheless Ultrasonography was particularly useful imaging modality for the pediatric abdominal tumors. IVP findings were renal displacement, caliceopelvic system distortion or nonvisualization of kidney, these information was helpful in determining the location of tumors. CT scan showed homogenous or inhomogeneous, cystic or solid, mass with their anatomic location. 4. Ultrasonography was the most widely used specific diagnostic method, but had limited value in detecting the anatomic location of tumors. CT scan was superior to ultrasound for determining the extent of tumors.
