63 cases of meningitis in children were reviewed to study correlation between brain CT findings and clinical course. We divided 63 cases into 3 groups according to clinical course, that is , Group I :Healed without significant sequelae. Group II: Discharged with sequelae such as neurologic deficit or complicated clinical course. Group III : Expired or considered to be expired after hopeless discharge. The CT finding were retrospectively analyzed and compared with each clinical group. We drawed several conclusions as follows; 1. The wrost prognostic CT finding is dirty basal cisternal enhancement. (Group I only 5%, Group II 50%, Group III 45%).2. Focal brain parenchymal lesion, especially multiple, such as granuloma and infarct shows unfavorable clinical outcome, that is, high rate of Group III and evident neurologic deficit, in contrast to only 7% of Group I. 3. In 7 cases of which CT finding is only hydrocephalus, the prognosis is rather favorable, that is, 57% were Group I, 43% were improved after V-P shunt (Group II) and no Group III. But hydrocephalus with dirty disternal enhancement results in grave prognosis, that is, Group I only 8%, Grouop II 54%, Group III 38%, With regard to overall hydrocephalus, predilectron for good or bad prognosis can't be mentioned. 4. No prognostic difference were noted between presence and absence of periventricular low desnity in hydrocephalus. 5. CSF pressure of hydrocephalus ismostly high (over 20cm H20). but normal pressure hydrocephalus were noted in 24%. CSF pressure of normal ventriclesize is mostly under 18cm H2O) but high pressure were noted in 18% of the nomral sized venticle (most of them shows intracranial space occupying lesion such as granuloma, acute infarct, subdural effusion, etc). 6. Most of diffuse braine swelling, diffuse brain atrophy and subdural effusion result in Group I, that is, favorable clinical outcome. 7. Normal CT findings ar found in 29%, of which 61% belong to Group I and 31% to Group II.

The utility of computerized tomogaphy in the study of the anatomy, and pathology of the musculoskeletal system has been the subject of considerable interest since the introduction of CT scanning. It provides an accurate and detailed cross-sectional image of normal anatomical structures and shows the relation of masses to these structures. In order to assess the utility of computed tomography, we analyzed the 92 clinical cases. We divided our experience into three major categories: spinal lesios, pelvic (including hip) lesions, and lesions of extremities. The advent of a new prototype scanning device has made it possible to exam a variety of abonormalities in the orthopedic diseases in a manner not previously possible.

Backgrounds: Thyroid hormones play a fundamental role in the initiation and maintenance of somatic growth in mammalian species, and the insulin-like growth factors(IGFs) occupy a position of central importance in the growth of all tissues. To evaluate the changes in serum insulin-like growth factor-I(IGF-I) and insulin-like growth factor binding proteins in hyperthyroid and hypothyroid patients, sera was obtained from 19 hyperthyroid patients, 9 hypothyroid patients, and 10 healthy volunteers. Methods: IGF-I concentration was determined by radioimmunoassay, and changes in IGFBPs were assesed by Western Ligand Blotting. To evaluate the binding pattern of IGF-I & IGFBPs, autoradiographs were obtained. Results & Conclusion: IGF-I levels were increased significantly in hyperthyroid patients(mean ±SE, 267.88±9.80 ng/ml, p<0.05) and decreased significantly in hypothyroid patients(154.81±1.43 ng/ml, p<0.01) compaired to healthy control group(209.45±.60 ng/ml). Autoradiograph of serum IGFBPs from patients with hyperthyroidism and hypothyroidism did not show any change in the intensity of IGFBP-3 bands(40-45 KD) and IGFBP-1 bands, but in hyperthyroid patients, it showed increased intensity of IGFBP-2 band compared to healthy control group and hypothyroid patients.

PURPOSE: We evaluated the MR and CT findings of the masticator space lesions in order to identify the differences among the malignant and benign tumors and infectious conditions. MATERIALS AND METHODS: MR and CT findings in 46 cases with proven masticator space lesions were reviewed retrospectively. We analysed the involvement of masticator muscles, adjacent spaces, orbit and intracrahium, homogeneity, necrosis, cystic changes, growth patterns, calcifications, enhancement patterns, MR signal intensity, and CT attenuation. RESULTS: Among the 29 cases of malignant tumors, seven cases were mandibular tumors including four chondrosarcomas, and 22 cases were extramandibular tumors. Malignant tumors of mandibular origin showed large masses with severe bone destruction and epicenter of mandible. Extramandiblular malignant tumors showed the epicenter out of the mandible and less severe bone destruction than mandibular tumors: Among the nine benign tumors, four cases were ameloblastomas which showed the well-defined masses and the expansion of the mandible, and four cases were extramandibular tumors which showed well-marginated extramandibular masses with no bone destruction. Among the eight infectious conditions, five cases were mandibular osteomyelitis with or without abscess formations, and the other three cases were infections from adjacent soft tissue or limited to the soft tissue. CONCLUSION: By careful observations of growth patterns, involvement of the masticator and adjacent spaces, bone changes, and epicenter of the lesions, one can discriminate a mandibular lesion from an extramandibular lesion. With this approach, it is thought to be easier to suggest a dignosis among a wide spectrum of masticator lesions.

Castleman disease rarely presents as an isolated retroperitoneal mass. We report two cases of retroperitoneal Castleman disease. Sonography showed hypoechoic mass. in two CT demonstrated homogeneously enhancing mass in two cases and calcifications in one case.

PURPOSE: To analyze the serial changes of proton magnetic resonance (MR) spectra in the abscess and to determine the effect of the antibiotic treatment on the metabolite patterns. MATERIALS AND METHODS: MR imaging and MR spectroscopy of an experimentally induced abscess were performed sequentially for four weeks at interval of one week in both the control group (n=5) and the antibiotic treatment group (n=5). On MR imaging, the shape and the size of the abscess were analyzed. On MR spectroscopy, the resonance peaks of metabolites were assigned on the basis of reported peaks in the literature. The metabolite ratios measured by using N-acetyl alanine as an external reference and by using lipid as an internal reference were compared in both the control and treatment groups. RESULTS: The abscesses were seen as cystic masses on MR imaging. On MR spectroscopy, the variable peaks of acetate, succinate and various amino acids, which are the metabolites of infection, were identified in the control and antibiotic treatment groups. The most frequent peak was that of acetate at 1.92 ppm (70%). Both the peak ratios of acetate to lipid and acetate to external reference tended to decrease in the treatment group while the ratios did not change significantly in the control group. CONCLUSION: MR spectroscopy is useful not only for the diagnosis of abscess but also for monitoring the evolution of the abscess by using the acetate peak.
