PURPOSE: Differential diagnosis of solitary pulmonary nodule with cavity includes lung abscess, tuberculoma, bronchogenic carcinoma, metastasis and trauma, etc. We analyzed the CT appearance of tubercuioma presenting as a solitary pulmonary nodule with cavity and describe the findings which suggest tuberculoma in the differential dignosis of soliary pulmonary nodule with cavity. MATERIALS AND METHODS: 25 patients with solitary pulmonary nodule(diameter less than 4 cm) without surrounding parenchymal consolidation on chest radiograph, who had a cavity within the nodule on CT, were included in our study. Density of the nodule, maximal wall thickness, the character of inner and outer wall margin, location of cavity within the nodule, location of the nodule, presence or absence of satellite lesions and calcification were analyzed. RESULTS: Solitary tuberculoma with cavity showed maximal wall thickness more than 15 mm in 40%(10/25) and 5-14 mm in 56%(14/25), eccentric cavitation in 84%(21/25) and concentric cavitation in 16%(4/25), spiculated outer wall margin in 56%(14/15) and Iobulated margin in 32%(8/25), smooth inner wall margin in 60%(15/25) and nodular margin in 40%(10/25). CT density of the cavity wall compared with the chest wall muscle was low in 84%(21/25) and isodense in 16%(4/25). Accompanying satellite lesions were seen in 84% (21/25) and calcification was visible in 28%(7/25). CONCLUSION: The CT findings of solitary tuberculoma with cavity are relative peripheral location, eccentric cavitation, finely spiculated outer wall margin, and mean maximal wall thickness of 13.2 mm, which are also the common features of malignant nodule. However, relative low density of the nodule compared to the chest wall muscle and surrounding satellite lesions can be additional clues favoring solitary tuberculoma with cavity on CT.

The association of gastric tubular adenoma and adenocarcinoma is already well known. Then, are those two pathologic lesions merely incidentally coexisting or does the one evolve to the other? That is a longstanding controversy. Nowadays, as is the case with the colonic tubular adenoma, the hypothesis that gastric tubular adenoma may be a precancerous lesion is generally accepted. However the direct evidences are rare. We report a clear case proving the potential of direct malignant transformation of gastric tubular adenorna through the 9-year close endoscopic follow-up. The developed cancer is well differentiated, surrounded with background tubular adenoma and limited to the submucosal layer.

PURPOSE: The prevalence of developmental delay is 5-10% of the total pediatric population and early diagnosis and proper intervention are essential but a challenge for clinicians. We performed this study for several purposes. First is to know the distribution & characteristics of developmental disorders in Korea. Second is to identify all possible causes of these disorders through a multidisciplinary diagnostic approach, and thus to find out the clinical variables that are helpful in finding the etiology. And finally to develop a useful protocol that eliminates the cost of unnecessary tests and raises the diagnostic rate of the cause. METHODS: 518 patients(M 349, F 169) were studied who visited Ilsan Hospital Developmental Disorder Clinic(DDC) for the evaluation of developmental delay from April 2001 to Jan 2005. RESULTS: The mean age was 51.5+/-32.9 months, ranging from 2 months to 16.0 years of age with a majority of the preschool children(<6 yr)(79.3%). Phenomenological diagnosis consisted of 133 cases of mental retardation, 122 cases of autistic disorders, 101 cases of delayed language disorders, 27 cases of cerebral palsies, and 91 cases labeled as simple developmental delay requiring follow up due to age less than 2 years of age. Etiologic diagnosis was obtained in 119 cases(22.9%) out the 518 cases of developmental delays. 37 cases of chromosomal anomalies, 23 cases of Periventricular leukomalacia and hypoxic ischemic encephalopathy, 21 cases of syndromes, 7 cases of malformation of cortical development, 4 cases of myopathies, 4 cases of neuropathies, and 4 cases of cerebral infarctions were found. Among the clinical variables, low birth weight, facial dysmorphism, hypotonia, focal neurologic signs, and abnormalities in MRI, chromosome, EEG and EMG studies contributed to the yields of etiologic diagnosis significantly. CONCLUSION: Possible etiology was determined in about 23% of the subjects. The most important part of the assessment for the identification of etiology is thorough history taking, physical and neurologic examination. Neuroimaging study is useful in case of micro or macrocephaly, focal neurologic signs. Genetic studies increasingly produce a yield, when there is family history of inherited disorder and there are dysmorphic features. Routine metabolic screening test has limited utility. Development of a useful screening protocol adequate for Korean situation is required.

In order to find a highly efficient compound against Clonorchis infection, the anthelmintic activity of disophenol, Tremerad (SYD-230), dithiazanine iodide, dehydroemetine-late-release tablets(RO 1-9334/20), niridazole (Ambilhar), hexachlorophene (G-11), Hetol(1, 4-bis-trichloromethylbenzol) and Bilevon (niclofolan) was tested against Clonorchis sinensis experimentally infected rabbits. All drugs showed a progressive increase in efficacy as the dose rate. They were highly efficient against Clonorchis infection if sufficiently high, potentially toxic doses were given. The efficacy was evaluated by the number of detected worms with vital condition at autopsy after the treatment with above drugs. The high efficacy was observed at the following dose rates of each drugs, i.e. disophenol at a single dose of 30 mg/kg, Tremerad at the daily dose of 200 mg/kg for 10 consecutive days, dithiazanine iodide at the daily dose of 50 mg/kg for 6 consecutive days, dehydroemetine at the daily dose of 10 mg/kg for 10 consecutive days, hexachlorophene at the daily dose of 20 mg/kg for 10 to 15 consecutive days, Hetol at the daily doses from 50 to 100 mg/kg for 5 to 10 consecutive days, and Bilevon at a single dose of 8 mg/kg. Moderate effectiveness was shown in niridazole at the dose of 25 mg/kg for 10 days medication. The use of these anthelmintics for the clinical treatment of Clonorchis sinensis infection is discussed.

PURPOSE: To evaluate the degree of contrast enhancement of intracranial tumors on delayed (6-8min.) MR imaging after administration of Gd-DTPA. MATERIALS AND METHODS: Both immediate and delayed post-contrast MR imagings were studied prospectively in 35 patients. with brain tumors (11 gliomas, 6 meningiomas, 4 neurinomas, 5 parencymal metastases, 5 hemangioblastoma, 4 others) at either 0.5 T or 2.0 T unit. After precontrast TI-, proton-density, and T2-weighted spin echo images were obtained, each patient underwent Tl-weighted imaging immediately following infusion of 0.1 mmol/Kg of Gd-DTPA. Subsequently, the second postcontrast Tl-weighted images were obtained with no additional injection of the contrast media. Time-interval between the postcontrast immediate and the delayed images was approximately 6-8 minutes. Degree of contrast enhancement of the lesions was assessed both visually and quantitatively. For quantitative study, contrast enhancement ratio(CER) of tumors was calculated in both immediate and delayed post-contrast images. RESULTS: There was stronger visual enhancement in 7 of 11 cases with gliomas and 3 of 5 cases with parenchymal metastasis on delayed images when compared with immediate images, whereas all 10 cases of extraaxial tumors(meningiomas and neurinomas) showed decreased enhancement on delayed images. Quantitatively, mean CERs of gliomas and metastases were higher on delayed study than on immediate study by 20. 5% and 49.2%, respectively. Extraaxial tumors showed decrease of CER on delayed study by 19.7% as compared with that of immediate study. Hemangioblastomas showed visually poor enhancement on delayed image in 4 cases and equal enhancement on both immediate and delayed images in remaining one case, and quantitatively demonstrated decrease of CER on delayed study by 15.4%. CONCLUSION: Since there was more conspicuous contrast enhancement in many intraaxial tumors such as gliomas and metastases on 6-8 minutes delayed post-contrast MR study, the delayed post-contrast study may be needed in some intraaxial tumors for their characterization, and may also be helpful for the differential diagnosis between intraaxial and extraaxial tumors.
