In general, meningiomas are slowly growing benign neoplasms originating from specialized meningothelial cells in arachnoid granulation, but have a tendency to be locally invasive and recurrent. Meningiomas very rarely metastasize outside the nervous system, occurring in less than 0.1%. We report the CT and MR findings of a case of a solitary benign syncytial meningioma showing recurrent multiple tumors and malignant progression with eventual bone metastasis to rib after six surgical extirpations during six years.

Chest CT is the most useful modality in the diagnosis of primary lung cancer, particularly in patients with recurrent pneumonia which are resistant to antibiotic therapy and in high risk age groups for cancer, The purpose of this examination is to assess the usefulness of CT in pneumonia types of lung cancer. The authors retrospectively analyzed 15 histologically proven cases of pneumonic type lung cancer, which had no evidence of primary lung mass, mediastinal lymphadenopathy or other metastatic lesion on piain chest radiography. On CT scan, a primary lung mass was identified in 13 patients(87%, bronchial obstruction was identified in 12 patients(80%), and metastatic foci was found in the bone(one patient), liver(one patient), and spleen(one patients). In Conclusion, CT scan is a useful method to detect the mediastinal lymphadenopathy or pulmonary mass and also should be the initial radiolographic procedure for diagnosis of lung cancer in patients with recurrent pneumonia on simple chest radiography.

Castleman's disease(Giant lymph node hyperplasia) is a pathologic entity of unknown etilogy, as attested to bythe number of names it has received, lymphoid hamartoma, angiomatous hamartoma, and giant lymph node, etc.Although the mediastinum is its most common location, it also occures in other areas of the body, usually wherelymph nodes are normally found. Authors have been experienced 2 cases of histologically porven Castleman's diseaseduring recent 3 years in Kyung Hee University Hospital, and present its radiological and pathological findings asmediastinal mass.

Reconstruction of soft tissue dejects on the lower leg and foot remains a difficult challenge for surgeons. If the deject was large and complicated by bone defects, an excellent result could be obtained with free tissue transfer. In case of no bony problem, no major infection and relatively small defect, a local flap is more Convenient and economic than free tissue transfer because of its simple, one-stage and reliable operation. The vascularization of the subcutaneous tissue reveals the predominance of the vascular network in this layer with regard to the dermal or fascial plane. The dermal vascular network at the donor site is sufficient to let the skin survive without its underlying subcutaneous vascular support. Distally based adipofascial flaps, nourished by the lower perforator originating from the major vessel as link pattern were. used successfully for reconstruction of the bone and/or tendon exposure of the lower leg and foot in 10 patients. Between February 1992 and December 1995, ten cases underwent this procedure to reconstruct soft tissue defect on the lower leg and foot. The average age of the patients was 50.6 years (range 5 - 73years). Follow-up was from 10 months to 38 months (mean 21 months). The average time of the operation was about 2 hours 18 minutes. The length to width ratio of adipofascial flap was 2.4 - 5.0 : 1 (mean 3.4 : 1). The advantages of this method are easy dissection, short operation, preservation of the major vascular pericles of the lower limb, skin preservation at the donor site, thus preserve the shape of the limb and minimize donor site scar, and versatility (it is supple and can adapt to every surface, and it can be grafted on the deep or the superficial side). In conclusion, this technique is an useful and alternative method for reconstruction of soft tissue defects on the lower leg and foot in selected cases.

Authors analyzed 72 cases of abdominal CT of Korean adults who didn't have any medical reasons to believe thespleen was abnormal. The following criteria were measured with mulitiple transverse scanning of the entire lengthof spleen (height, breadth, thickness) & relationship with fixed midline structure, the spine( the shortestdistance from midline to medial edge of spleen, the longest distance from anterior margin of vertebral body toanterior tip of spleen). The reults were as follows; 1. The average size in adult was 8.0±1.5cm in height,8.6±1.2cm in breadth and 3.4±0.6cm in thickness; in adult female, 7.8±1.1cm, 8.4±1.0cm and 3.4±0.6cm,respectively; total average, 7.9±1.3cm, 8.5±1.1cm and 3.4±0.6cm, respectively. No remarkable difference wasnoted between both sexes and age groups. 2. The shortest distance from midline to medial edge of spleen was4.1±1.1.cm in male, 3.6±1.0cm in female and total average of 3.9±1.1cm. There was remarkable difference betweenboth sexes(p<0.005) but not between age groups. 3. The longest distance from anterior margin of vertebral body toanterior edge of spleen was 2.3±1.7cm in male, 2.0±1.4cm in female and total average of 2.2±1.6cm. Noremarkable difference was seen between both sexes and age groups.

Ultrasonography is a predominantly accurate, relatively simple unique diagnsotic method of obstructive jaundice. The ultrasonographic findings of obstructive jaundice are dilated intra- and extrahepatic duct with intraluminal hyperreflective echo or mass in and/or around the bile duct. The superiority of high resolution real time ultrasonography for the diagnosis of obstructive jaundice is based on the easy detectability of extra-and intrahepatic bile ducts by its multiple sectional images in a short time, the flexibility of probe and the small crystal size. Author evaluated real time sonographic findings 46 obstructive jaundice patients confirmed by surgery or radiographical examinations. The results were: 1. Diameter of extrahepatic duct in obstructive jaundice were varied from normal to 4.0 cm, mostly 8 to 10 mm in diameter (26%). Degree of dilatation of biliary duct appeared more prominent in cancer patients than any other causes of obstruction. 2. The site of obstruction was detected in85% (39/46) and its common site was common bile duct in 63% (29/46). 3. The diagnostic accuracy of choledocholithiasis and cancer was 82% (22/27) and 44% (4/9), respectively. Diagnostic accuracy of the real time ultrasonography in obstructive jaundice was over all 75% (34/46).

Paragonimiasis is widely distributed in Far East and Southeast Asia, particularly in Korea. The centralnervous system is the most frequent location for paragonimiasis outside the lungs. We analized the computedtomographic findings of 17 cases which were diagnosed pathologically and clinically as cerebral paragonimiasis.The results were as follows; 1. The ratio of male to female was 10:7 and about 88% of cases were under the age of40 years. 2. The common location so cerebral paragonimiasis were the occipital (12 cases ) and temporal (11 cases) lobes. 3. Precontrast CT findings of cerebral paragonimiasis were low density with calcifications in 6 cases,low and isodensities in 4 cases, mixed densities in 3 cases, only low density in 2 cases and only calcification sin 2 cases. Hydrocephalus (7 cases), mass effect (6 cases), atrophic change(6 cases) and cyst formation (3 cases)were associated. 4. The shape of calcifications in CT scan were soap-bubble or ring in 6 cases, nodular or oval in6 cases, stippled in 4 cases and amorphous conglomerated in 2 cases. 5. The contrast-enhanced 8 cases were 5 ringor rim like, 2 nodular and 1 irregular enhancements, while 9 cases were not enhanced.

PURPOSE: Proximal subclavian artery stenosis is relatively uncommon and usually asymptomatic. It is well known that the retrograde flow through ipsilateral vertebral artery is not related with onset of clinical symptom and not a definite indication of treatment. METHOD: We reviewed six patients including four patients who underwent percutaneous transluminal angioplasty to correct the difference of blood pressure between arms. RESULT: Nobody shows marked clinical improvement even though there was definite technical success. CONCLLUSION: It is considered that angioplasty could be done for the treatment in most of subclavian artery stenosis.
