PURPOSE: It is not easy to determine the cause of pulmonary consolidative lesion. Even without any definite mass, malignancy cannot be ruled out. And sometimes, it is difficult to differentiate tuberculosis from pneumonia. To differentiate malignant consolidative lesion from benign one, we studied patterns of air bronchogram, mucoid impaction, and computed tomographic anglogram etc. MATERIALS AND METHODS: Fifty seven cases of pulmonary consolidative lesions(23 cases of malignancy,34 cases of benign lesion) were retrospectively reviewed by three radiologists. RESULTS: Among the 28 cases which showed a little air bronchogram(less than 1/3 of the whole lesion in volumetric measure with the eye) 19 cases were malignancy and nine cases were benign lesions. All of the 12 cases which showed profound air bronchogram over 2/3 of the whole lesion were benign lesions. Bronchiectasis was detected in 31 cases(four of malignancy and 27 of benign lesions). Among the 20 cases which didn't show the mucoid impaction five cases were malignancy and 15 cases were benign lesions. Out of eight cases with mucoid impaction filling the long segments(branching tree shape), seven cases were malignancy and one case was benign lesion. So called CT anglogram was detected in nine cases of malignancy and two cases of benign lesions. All of nine cases of malignancy showed CT anglogram which was like arborizing tree. CONCLUSION: Scanty air bronchogram, profound arborizing mucoid impaction and/or CT angoigram within consolidative lesion could suggest malignancy.

The appendiceal mucocele is very rare disease of 0.2% incidence. About 24% of patients are asymptomatic and symptomatic patients present with pain in the right lower quadrant of abdomen in 64%, plapable maas in the right lower quadrant of abdomen in 50%, and rarely, melena, hematochezia, anemia, diarrhea, malaise, and abdominal distension. The gastrointestinal bleeding may be presented in the patient with intussusception, but the massive bleeding is generally absent. We report a case of appendiceal mucocele accompanying with gastrointestinal bleeding and review of literature.

Primary gastrointestinal lymphoma primarily confined to gastrointestinal tract is relatively rare diaease. Although the lymphoma primarily involved colorectum or small bowel was commonly reported than primary gastric lymphoma in Korea, the concurrent primary lymphoma of colon and small bowel is very rare in reported cases. We report a case of combined primary malignant lymphoma of the jejunum and cecum, who was admitted due to melena and anemia. She had right hemicolectomy and end-to-side ileotransverse colostomy at 2 months ago, due to primary colon lymphoma. The laparotomy was performed and identified hard, 2 x 3 cm sized masses on distal 25 cm, 80 cm and 150 cm from the Treitz ligament. The histology of these small ma showed histiocytic lymphoma as same as cecal specimen. In general, the small bowel lymphoma shaws poor prognosis than gastric or colorectal lymphoma due to diffieulty in diagnosis and late symptoms, but this problem could be resolved through the knowledge about primary gastrointestinal lymphoma and the development of diagnostic methods.

Of several possible configurations of pin fixation of a displaced supracondylar fracture of the humerus in children, the medial and lateral crossed pinning technique has been known to provide the greatest resistance to gross rotational displacement. A new technique with ipsilateral two lateral crossed pins was devised so as to avoid the ulnar nerve injury with good stability for fracture site. During the period from 1992 to 1994, 18 children with displaced supracondylar fracture of the humerus were treated by closed reduction and ipsilateral two lateral crossed pinning. Eighty nine percents of the final results were satisfactory. There were no ulnar nerve injuries and fixation loss in all cases from the treatment. This is a safe, simple and reliable technique for providing the good stability of fracture site as well as avoiding the ulnar nerve injury.

Congenital adrenal hyperplasia is inherited disorder of adrenal steroidogenesis. 21-hydroxylase deficiency is the most commone enzymatic defect and is divided into classic and late-onset or nonclassic forms. Both classic non-classic 21-hydrozylase deficiencies are inherited in a recessive manner as allelic variants. But it is rare that happened in twin infants. Chief complaints of affected twins in our case were ambiguous genitalia, hyperpigmentation and dehydrations. They were revealed into hyponatremia, hyperkalemia and increased amount of serum progesterone, 17-hydroxyprogesterone and urinary 17-ketosteroid excretion and were administered with DOCA, 9alpha-fluorohydrocortisone, hydrocortisone to control the electrolyte imbalance. And now, both of them are going to normal ratio of weight gain and body growth.

PURPOSE: The characterization of all recognizable chromosomal rearrangements was dis- turbed by technical limitation of conventional cytogenetic methods. Recently, the strong usefullness of generation of chromosome specific painting probes in identification of marker chromosomes has proven. This study was intended to analyze the chromosomal aberrations in human ovarian cancer cell line, SNU-8, by G-banding and multiple paintings. MATERIALS AND METHODS: Human ovarian cancer cell line, SNU-8 was cultured and harvested for cytogenetic analysis. Routine karyotyping was performed. For complete analysis of chromosomal aberrations, human chromosome-specific painting probes were constructed from somatic hybrid cells. The origins of the unidentified marker chromosomes were analyzed by fluorescent in situ hybridization (FISH) with these painting probes. RESULTS: All chromosome alterations were confirmed by the use of multiple chromosome paintings, which also demonstrated a number of additional alterations. SNU-8 had the karyotype 62-69,XXX, + der(1;10)(q10;p10),der(3;18) (q10;p10)X2,-4,+ 5,+ 7,del(9)(q21)X2,-11,-13,-15,-16,der(17;19)(q10;q10) X2, + 20,-22[cp51]. CONCLUSION: The chromosomal aberrations of SNU-8 cell line was effectively analyzed by FISH with these painting probes, and the approach methods of this study can be applied to cytogenetic analysis of chromosomal aberrations in the other cancers.

The examination of the optic nerve is an important part of every examination of the fundus. In attempting to determine weather or not a pathologic process is present, it is essential that the normal disk and its varitions, as well as the congenital anomalies, be thoroughly understood. For this reason the major portion of this study will be devoted to the normal disk shape and its congenital variations.

Hirayama disease usually selectively involves lower cervical myotomes (C8, T1). Thus, patients usually manifest with atrophy and weakness of small hand muscle. Predominant isolated involvement of proximal arm is rarely reported in Hirayama disease. Here, we report a case of Hirayama disease who had focal weakness and wasting, mainly confined to right biceps brachii muscle, with prominent shifting of dural sac in C4-5 segment by dynamic flexion magnetic resonance imaging (dfMRI), which may explain this unusual distribution of the disease.
