이영춘,서흥석,함창곡 한양대학교 의과대학 1988 한양의대 학술지 Vol.8 No.2

The lung is primary site of infection with M. pneumoniae, other sites are the skin, central nervous system, heart, and joint. School-aged children and young adult experienced high attack rate, especially in a defined group or population, such as school and military pupulation. Authors reviewed clinical and radiological features of 34 cases of serologically proven Mycoplasma pneumonia in hospitalized children from January 1986 to January 1988. Male to female ratio was 24:10 (2.4:1) and 61.8% of them were 5 through 8 year old. The clinical symptoms were cough, sputum, sore throat, fever and duration of the symptom before admission was from 6 days to 10 days. The radiologic findings were bronchopneumonic pattern in 14.1%, with lobar in 26.5% and segmental in 14.7%, normal in 11.8%, lobal atelectasis in 2.9%. Mean radiologic resolution period was 8.5% days in bronchopneumonia pattern and 6.8 days in alveolar consolidation. Therefore more rapid resolution was observed in alveolar consolidation than bronchopneumonia. Extrapulmonary manifestations were hematuria, skin rash and hepatomegaly and otitis media.

The authors experienced 2 cases of Sturge-Weber syndrome which showed typical appearance of the disease, clinically and radiologically. Especially, these showed extensive calcification and diffuse cortical atrophy of frontal and parietal lobe, which was known as rarely demonstrated findings. Thus the authors report these cases with emphasis in plain skull and brain C.T. findings with a brief review of the literatures.

Purpose : To determine the incidence of identifying organism from the diffusely calcified thoracic mass which is ususlly caused by tuberculosis in Korea and has been considered needless to be followed up and, if organisms are identified, to decide whether those patients should be medicated or not. Materials and methods : From consecutive patients who had undergone percutaneous needle aspiration(PNA) of thoracic lesion, we selected patients who met the following criteria : (a) visible calcification in more than half of the lesion volume on CT(b) negative acid-fast bacilli (AFB) in sputum. These included 6 patients with pulomonary nodules and one with a paratracheal lymph node. AFB staining was done of PNA specimen and follow-up radiographs of patients with positive AFB lesion were reviewed after antituberculous chemotherapy. Result : AFB was demonstrated in six(85.7%) and only caseation necrosis in the other one. Antituberculous medication was done in all Among five patients whose radiographs were available during the follow-up period of 1-17 months after medication, only one showed silight decrease in size. Conclusion : Although the effect of antituberculous chemotherapy is doubtful, careful follow-up is needed even to the tuberculous lesion with diffuse calcification because orgainisms are present in those lesions.

Cerebral primitive neuroectodermal tumor (PNET) is a neoplasm of children and young individuals that occurs predominantly in the supratentorial compartment. It is a diagnosed as a genetic term for cerebellar medulloblastomas and for neoplasm which are morphologically indistinguishable from the medulloblastoma but are located at other sites in the CNS. In this report, we retrospectively reviewed and analyzed 7CT and 2 MR findings in 7 patients with pathologically-proven PNET or radiologically characteristic PNET findings. The most characteristic features of the PNETs was a well-defined oval or round large mass with/without intratumoral calcification and hemorrhage in the cerebral hemisphere, especially in the parietal and frontal lobe. There was only minimal surrounding edema. The CT and MR findings demonstrated solid portion and cystic area but mainly enhanced in the solid portion.

For the study of correlation of ct number and fatty content of the liver, total 35 rabbits were used. The rabbits were divided into one control and three experimental groups according to the amount of carbon tetrachloride, administered 1 ml, 2 ml and 3 ml per kg of body weight respectively. The carbon tetrachloride was administered via intragastric route. CT was performed 72 hours following administration of carbon tetrachloride, and immediately prior to CT scan each rabbit was anesthetized by means of IM injection of ketamine and IV injection of succinylcholine to stop motion and respiration. CT numbers were measurd and histological study for the deposition of fat in the liver tissue was done. Also biochemical analysis of lipid in the blood and in the extraction of liver tissue was performed. Comparison of CT number with biochemical and histological data was done. The results were as follows: 1. In each experimental group, the degree of accumulation of fat in the liver was proportional to the amount of carbon tetrachloride. 2. Degree of decreasing CT number was correlated with the increase in the accumulation of fat in the liver. 3. In the control and experimental (1,2,3) groups, when the amount of carbon tetrachloride increased, the amount of total lipid, cholesterol and triglyceride on biochemical analysis of the liver increased. Also increase in the amount of plasma lipids on biochemical analysis and a great degree of increase in accumulation of fat in the liver on histological examination were seen. But no changes in the amounts of phospholipid and protein on biochemical analysis of the liver were noticed. 4. Increase in the amount of total lipid could make a change in the CT number of the liver remakably (r=-0.63). As the amount of cholesterol and triglyceride increased, the CT number of the liver decreased (r=-0.61 and r=-0-.76 respectively). But there was no significant correlation between the amount of protein and phospholipid and the degree of decrease in CT number. 5. Mean values of CT number in normal, grade 1, grade 2, grade 3 and grade 4 according to the degree of histological changes were 67.46±2.24, 58.53±3.06, 49.43±6.81, 39.49±9.69, 20.62±8.04 respectively. The reduction of CT number was correlated with the accumulation of fat on histological examination.

MR findings of 32 cases of histologically proven pineal region masses and mass-like lesions were analyzed retrospectively to evaluate characteristics of their signal intensity and morphology. MRI was performed on a 1.5T(GE/Signa) or 0.35T(Diasonics) system using spin-echo sequences. The lesions included germinoma(9 cases), teratoma(3), embryonal cell carcinoma(1), choriocarcinoma(1), glial cyst(3), dermoid(1), epidermoid(2), pineocytoma(2), pineoblastoma(2) meningioma(3), astrocytoma(3), CVM(1) and AVM(1). MRI is quite helpful to suggest pineal region masses and mass-like lesions as glial cyst, teratoma, dermoid, epidermoid, pineoblastoma, meningioma, CVM, AVM and also helpful to decide the origin or location of the mass with identifying displacement of the internal cerebral vein, vein of Galen and basal vein of Rosenthal which showed signal void of flow on both T1 and T2 weighted images.

The spines have bony structures as well as a spinal canal and spinal cord. The lumber spines are most commonly affected by congenital or acquired diseases because of their widest range of motion and heaviest weight bearing. There are various kinds of radiographic examinations to diagnose the disease of the lumber spine : simple spine radiography (A-P, lateral and both oblique views), tomography, myelography, spinal venography and discography, etc. The lesions affecting the bony struct ures are bestseen in the simple radiogram and tomogram. The lesion, however, developed within the spinal canal or in the cord are mainly demonstrated in the myelogram. So, without any evidence of bone changes in a case of spinal cord tumor, it is difficult to diagnose only by simple radiogram. In 1934, Elsberg and Dyke published normal values for interpediculate distances as determined on simple radiograms of the adult human spine, and they insisted that the measurement of the interpediculate dis ances was helpful in the diagnosis of the spinal cord tumor. Thereafter, Hinck and Schwarz published normal values for interpediculate distances f normal child and adult. The sagittal diameters of the cervical and lumbar spines were also measured by Hinck and Burrows. But, there was no previous report about the measurement for the diameter of subarachnoid space using normal myelogram. The author measured the tranaverse diameters of the dye column in the normal lumbar myelograms of 70 male and 30 female adults. The magnification ratio and individual differences were studied by the measurements of the transverse diameters of the 3rd lumbar spine in simple A-P radiogram and fluoroscopic radiogram transverse diameters of the 3rd lumbar spine in simple A-P radiogram and fluoroscopic radiogram of 10 males and 5 females. The magnification ratio of the fluoroscopic shadow to the simple of 10 males and 5 females. The magnification ratio of the fluoroscopic shadow to the simple radiogram was 1 2 times, and the individual differences were around 2 per cent of their values. The measurements of the dye column were carried out in 11 different levels. The widest dye column at the level of L-1 was determined to be the first measurement level, and the narrowest dye column just below the first level, to be second measurement level. The odd numbered levels were wider than the eve numbered levels because the nerve roots were at the odd numbered levels. The 12th measurement was taken between horizontal line draw through the bilateral neural sleeves of the 5th lumbar spine and the end of the cul-de-sac. All the values of the male were slightly bigger than those of female, but the differences were less than 1mm. The widest transverse diameter of the dye column was observed in the 7th measurement level where the 4th lumbar neural sleeves were located, and the values were 23.1$\pm$3.36mm. inmale and 22.5$\pm$3.30mm. in female. The narrowest transverse diameter was observed in the second and th rd lumbar interspace, and the values were 16.8$\pm$2.97mm. in male and 16.9$\pm$2.50mm in female. The transverse diameters of the 3rd lumber spines were measured in the same fluoroscopic films, and the means were 59.8$\pm$4.05mm. in male and 51.9$\pm$2.74mm. in female. But the values of each level were almost same even with the differences of the transversediameters of the 3rd lumbar spines. The individual differences of the intedpediculate distances of L-3 were very small, and there was no significant correlation between each value for dye column and each interpediculate distance of L-3. The diameter of the dye column in the L-3 was 71 per cent of interpediculate distance at the same level.
