PURPOSE: Dysembryoplastic neuroepithelial tumor (DNET) is a newly described, pathologically benign tumor arising within the supratentorial cortex. We reviewed the MR appearance of five patients with DNET, emphasizing the clinical and radiologic features. MATERIALS AND METHODS: MR images in the five patients (three male and two female) with a history of epileptic seizure and pathologically-proven DNET were retrospectively reviewed. We analyzed the location, configuration, signal intensity, contrast enhancement, vasogenic edema and calcifications of these tomors. RESULTS: The tumors were located mainly in the cortical to subcortical area with very little perifocal mass effect on MR imaging. They were essentially hypointense on T1-weighted imaging, and showed a hyperintense well circumscribed mass on T2-weighted imaging and a thick gyrus-like configuration was retained within the lesions. On contrast enhanced study, focal nodular enhancement was seen in one patient, and multifocal nodular enhancement in two. CONCLUSION: DNET is rare benign tumor resulting in often medically intractable epileptic seizure and shows a characteristic gyriform configuration, well-described lobular tumor margins and sometimes multifocal nodular enhancement. These radiologic features may aid in differentiating DNET from ganglioglioma and other gliomas.

Echocardiography was done on 51 cases with various cardiovascular disease and on 23 cases of normal control subjects from April, 1981 to March, 1982 in the Department of internal medicine, Eul Ji General Hospital, Seoul, Korea. The results obtained were as follows: 1. The left ventricular mass estimated by the measurements made with standard convention was 261+/-8gm in patient group and 126+/-6gm in control group. With penn convention, the left ventricular mass of the patients group was 297+/-11gm and that of control group was 127+/-6gm. The differences between both conventions were significant statistically. 2. In measurements made with standard convention, those who showed increased left ventricular posterior wall thickness were 37 cases(73%) and those who showed increased left ventricular internal dimension were 15 cases(29%). On the other hand, number of cases who showed increased left ventricular mass were 45 cases(88%) and this results suggested estimation of left ventricular mass seems to be more useful method in the diagnosis of left ventricular hypertrophy than simple measurements of left ventricular posterior wall thickness of left ventricular internal dimension. 3. The correlation coefficient between left ventricular mass and maximum voltage of electrocardiography, left ventricular posterior wall thickness left ventricularinternal dimension was 0.70, 0.74 0.51 respectively in standard method and 0.82, 0.76, 0.44 respectively in penn convention. Left ventricular mass was correlated fairly closely with the maximum voltage of electrocardiography and left ventricular posterior wall thickeness, less closely with the left ventricular internal dimension.

The Surgery Treatment Modality Committee of the Korean Gynecologic Oncology Group has determined to develop a surgical manual to facilitate clinical trials and to improve communication between investigators by standardizing and precisely describing operating procedures. The literature on anatomic terminology, identification of surgical components, and surgical techniques were reviewed and discussed in depth to develop a surgical manual for gynecologic oncology. The surgical procedures provided here represent the minimum requirements for participating in a clinical trial. These procedures should be described in the operation record form, and the pathologic findings obtained from the procedures should be recorded in the pathologic report form. Here, we describe surgical procedure for ovarian, fallopian tubal, and peritoneal cancers.

PURPOSE: To evaluate the usefulness of CT for assessing the location and cause of pathologic gastrointestinal perforation. MATERIALS AND METHODS: A retrospective analysis of abdominal CT was performed in 27 perforations of 26 patients with underlying gastrointestinal pathology. Fifteen benign and 12 malignant perforations consisted of five gastric cancers, one gastric ulcer, ten duodenal bulb ulcers, two bowel adhesions, one jejunal metastasis from lung cancer, one ileocolic Crohn's disease, one radiation colitis and six colon cancers. CT scans were evaluated for 1) diagnosis of bowel perforation, 2) assessment of the cause and site of perforation, and, in particular, differentiation between benignancy and malignancy, and 3) complications and their extent. RESULTS: CT easily detected varying amounts of free air or fluid collection, and infiltration or abscess formation adjacent to the main lesion, and the diagnosis of gastrointestinal perforation was therefore easy. In 11 of the 12 malignancies (92%), primary tumor was diagnosed, but detection of the site of perforation was possible in only seven cases (7/12, 58%). The 15 benign lesions revealed nonspecific CT findings, and the perforation site could be presumed in six (6/15, 40%). In one case of Crohn's disease, the primary cause was visualized. Among six colonic cancers, four pericolic abscesses and two fistulas to adjacent organs were found, but there was no evidence of diffuse peritonitis. CONCLUSION: CT was helpful to lead to optimal treatment of pathologic gastrointestinal On CT, the detectability of perforation, primary benign or malignant lesion, perforation site and extent of complication was high, and this modality was therefore a useful indicator of the optimal treatment for pathologic gastrointestinal perforations.

PURPOSE: To demonstrate the radiologic characteristics of the pelvic actinomycosis. MATERIALS AND METHODS: We retrospectively reviewed the radiologic findings of seven patients with pathologically proven pelvic actinomycosis and analyzed the anatomical location, characteristics of the lesion and alteration of surrounding structures. RESULTS: The location of the lesions were the ovary and adnexa(n=4), rectum(n=1), cecum and terminalileum(n=1), and bladder(n=1). Three of the seven patients had a past history of intrauterine devices.Post-contrast enhanced CT showed an ill-defined mass with inhomogeneous enhancement and a tendency to invade th esurrounding normal tissue plane. CONCLUSION: Pelvic actinomycosis should be included in differential diagnosis when an unusually aggressive infiltrative mass is located in the pelvic cavity, especially in a patient with long-term use of intrauterine contraceptive devices.

Bronchobiliary fistula is a rare disorder consisting of an abnormal communication between the bronchial tree and the biliary duct. In Western countries, trauma, postoperative biliary stenosis, and biliary lithiasis are the predominant causative factors of bronchobiliary fistula. Bilioptysis (bile stained sputum) is a pathognomic finding for bronchobiliary fistula. To date, there are just a few reported cases of bronchobiliary fistula after sclerosis of a liver cyst. We describe the case of a 74-year-old woman who developed bronchobiliary fistula after sclerosing therapy of a liver cyst. The diagnosis was confirmed by the presence of bilioptysis and the chest and dynamic liver CT findings. The patient was successfully treated with antibiotics and percutaneous transhepatic catheter drainage.

We report a case of Mycobacterium intracellulare pulmonary infection presenting as a solitary pulmonary nodule (SPN). A 35-year-old male was admitted due to a SPN in the right upper lobe which was detected on the chest radiography being examed due to recurrent cough for 1 year. The computed tomography (CT) revealed a spiculated nodule containing air-bronchogram, which was suspicious of malignancy. We performed transbronchial biopsy and the pathology showed granulomatous inflammation with caseous necrosis. Under the presumptive diagnosis of pulmonary tuberculosis, we started anti-tuberculous medication including isoniazid, rifampin, ethambutol, and pyrazinamide. In one month, however, the sputum culture was positive for Mycobacterium intracellulare. The follow-up chest CT showed slight aggravation of the previous lesions. Under the final diagnosis of Mycobacterium intracellulare pulmonary infection presenting as a solitary pulmonary nodule, we changed the regimen to rifampin, ethambutol, and clarithromycin. The follow-up chest CT after the completion of treatment, revealed resolution of the previous lesions.

The ulcerative colitis is a chronic inflammatory bowel disease with an unknown etiology. The major symptoms of ulcerative colitis are diarrhea, abdominal pain and hematochezia. However, arthritis, skin disorders, hepatobiliary inflammation and uveitis are occasionally recognized as systemic complications. Although there are few reports of coexistent pulmonary and inflammatory bowel disease, the lung is not generally considered to be a target organ in ulcerative colitis. We report a patient with ulcerative colitis-related bronchilolitis obliterans organizing pneumonia confirmed by video-assisted thoracoscopic surgery, who responded to corticosteroid therapy.

The middle mediastinum contains several important organs and pluripotent cells. It is difficult to make a definitive diagnosis in patients with middle mediastinal tumors due to a wide range of diseases. The likelihood of malignancy is influenced primarily by the following factors: patient age, size, tumor location, and the presence or absence of symptoms. We describe a case of a middle mediastinal tumor, which was suspected on chest x-ray; chest computed tomography revealed the eccentric mass of distal esophagus. This case emphasizes the diagnostic importance of the chest x-ray to the physicians. The possible differential diagnoses are reviewed.
