PURPOSE: To evaluate the clinical significance of the screening mammography in the detection of the breast diseases, especially breast carcinoma. MATERIALS AND METHODS: We analyzed 1,800 cases of mammography retrospectively. The mammography was done as a part of routine check in Health Counselling Center, Korea University Medical Center, during 9 months from November 1993 to July 1994. The age range was from 23 years to 76 years, mean 49.8 years, and the largest age group was 6th decade(31.4%). According to the mammographic findings, we divided the subjects into three groups; normal group, abnormal group in need of follow up study, abnormal group requiring biopsy. RESULT: On mammography, the normal group consisted of 1,534 cases(85%), and the abnormal group consisted of 266 cases(15%). The abnormal findings were benign-looking calcification(n=140), fibroadeno ma (n=29), fibrocystic changes (n=27), cyst(n=23), malignant lesion(n=15), lipoma(n=7), and others. In four of 15 cases, which were suspected to be malignant on mammograms, breast carcinoma was confirmed pathologically. In four cases of breast carcinoma, one was under 40 and the other 3 were over 50 years of age. All of the breast cancers were under 3cm in size, and the mammographic findings of breast cancer included spiculated margin(n=3), parenchymal disortion(n=3), malignant calcification(n=2) and enlarged axillary node (n=l). CONCLUSION: Screening mammogram is helpful for early detection of non-palpable breast cancer, especially for women over 50 years of age.

A previously healthy 16-month-old Korean girl with symptoms of fever, vomiting, and generalized tonic seizure was diagnosed to have Group D non-typhoid Salmonella meningitis. The patient was treated with ceftriaxone (100 mg/kg/day) and amikin (22.5 mg/kg/day) initially and ciprofloxacin (30 mg/kg/day) was added later because of clinical deterioration and disseminated intravascular coagulation. Brain CT performed on the second day showed a well-demarcated low density lesion in the right lentiform nucleus and both caudate nuclei, without evidence of increased intracranial pressure. MRI performed on the 11th day confirmed CT scan findings as well as right subdural fluid collection, brain atrophy, and ventriculomegaly. She underwent subdural drainage and later ventriculo-peritoneal shunt operation. Despite receiving intensive treatment, she still has severe neurologic sequelae. Our case shows that infarctions of basal ganglia and thalami are not specific for tuberculous meningitis and that meningitis complicated by infarction is indicative of grave prognosis.

Information on ethyl alcohol intoxication in children is scarce. It is generally believed that children are more vulnerable to ethyl alcohol intoxication than adults. However, little information has been published on the effects of ethanol in the pediatric age group. The incidence of hypoglycemia and convulsions following ethanol intoxication is not known. We report a fatal case of acute alcohol intoxication associated with hypoglycemia, convulsion and coma.

Renal abscess is rare in children and presents varying features which often lead to delay or error in diagnosis. Fever, lumbar pain, abdominal pain and occasional flank rnass are the usual presenting cornplaints but a high degree of suspicion is important for the early detection of renal abscess. Hematogenous seeding of the kidney or ascending infection from the urinary collecting system are two proposed mechanisms of renal abscess formation. Renal ultrasonography facilitates an earlier diagnosis and is also useful in establishing percutaneous drainage, which appears to be the treatment method of choice. We experienced a case of renal abscess which was treated by percutaneous aspiration and antibiotics without surgical intervention.

Immunoglobulin G4 (IgG4)-related lung disease has been actively studied over the past few years. Radiologic findings of IgG4-related lung disease vary among patients, but there are no long-term follow up studies regarding variations in imaging features over the course of disease progression. In two cases with relatively long-term follow up, diverse early and late computed tomography (CT) findings of IgG4-related lung disease are reviewed in this report. In contrast to nodular or diffuse ground-glass opacity, which was predominantly noted in CT scans at earlier stages of disease, honeycombing and traction bronchiectasis were regarded as late radiologic manifestations. Solid nodules might be visible in both early and late stages; however, development of new solid nodules and enlargement of preexisting nodules could occur during disease progression. Interlobular septal thickening and mediastinal/hilar lymphadenopathy were persistent, even in later stages of the disease. These findings might be useful in making an accurate and timely diagnosis of IgG4-related lung disease.

BACKGROUND: Pleural eosinophilia is rare and commonly considered to be an indicator of good prognosis. The diagnostic significance of eosinophilic pleural effusions remains controversial despite a century of observation and discussion. This study was conducted to assess the prevalence of eosinophilia in 446 consecutive samples of pleural fluid, to review the cause of eosinophilic pleural effusion and to determine whether the presence of eosinophils increases the likehood of benign conditions. METHOD: A retrospective analysis was performed upon patients that underwent first thoracentesis due to pleural effusion between January 1999 and December 1999. RESULTS: Eosinophilic pleural effusions were identified in 24 of the 446 patients (5.4%). Malignancy, parapneumonic effusion and tuberculosis were determined the major causes of pleural effusion (80.6%). Malignancy was diagnosed as frequently in eosinophilic effusions as in non-eosinophilic effusions (54.2% vs 50.5%, p=0.725). No difference was found in the prevalence of eosinophilic and non-eosinophilic effusion according to the etiology. The mean blood eosinophil ratio in patients with eosinophilic pleural effusion was 5.4% and no significant correlation existed between the blood and pleural eosinophilic count. CONCLUSION: Pleural eosinophilia is not helpful for differentiating benign and malignant etiology and is not related with blood eosinophilia or repeated tapping.

PURPOSE: To evaluate the usefulness of the coaxial technique in US-guided breast core biopsy. Materials andMethods : Using the coaxial technique, US-guided breast core biopsy was performed in 49 breast lesions (40patients). Under US-guidance the 17-gauge, 13 cm long introducer needle was positioned proximal to the lesion.Once the needle was in place, the central trocar was removed and was replaced with the core biopsy needle. We usedan 18-gauge, 16-cm-long core biopsy needle with a 17 mm specimen notch. Four to eight tissue specimens wereobtained from each lesion, and the quality and quantity of specimens, procedure time, and complications and theirrate were evaluated. RESULTS: For 48 of 49 lesions, specimens were adequate for histopathologic diagnosis, andthe findings were as follows : six cases of invasive ductal carcinoma, one of ductal carcinoma in situ, 29 offibrocystic disease, eight of fibroadenoma, two of chronic inflammation, and two of sclerosing lesion. In 12lesions agreement between the pathologic results of needle core biopsy and surgical results was 100%. Theprocedure time was about 15 minutes and no significant complications were noted. CONCLUSION: In breast corebiopsy, the coaxial technique is simple and time-saving, and compared with stan-dard breast core biopsy, may alsobe less traumatic and decrease the potential risk of seeding the biopsy tract with malignant cells.

Metastatic pulmonary calcification refers to calcium deposition in the normal pulmonary parenchyma and this deposition is secondary to abnormal calcium metabolism. The most common radiologic manifestation consists of poorly-defined nodular opacities that are mainly seen in the upper lung zone. We present here a case of metastatic pulmonary calcification that manifested as atypical, dense, calcium deposition in airspaces within the previously existing consolidation in the bilateral lower lobes, and this process was accelerated by pneumonia-complicated sepsis in a patient with hypercalcemia that was due to hyperparathyroidism.
