하해구,김기정 최신의학사 1972 最新醫學 Vol.15 No.9

A 33-year-old Korean male patient with leiomyosarcoma involving the right lateral thoracic wall was reported. Leiomyosarcoma in thoracic wall is extremely rare. This patient's chief complaints were dull pain with slowly growing bulging mass in right lateral thoracic wall for about 2 months duration. Physical examination on admission showed moderately developed and nourished man with a large hard bulging mass (about 1OX15cm in diameter) with severe tenderness around the right subaxillary region. Coughing and deep respiration made severe chest pain. Chest X-ray (P-A and lateral view) showed large diffuse soft tissue mass densities were occupying the entire right lateral thoracic wall and also involving the pleura with destructive bony missing of lateral parts of right 4th, 5th and 6th ribs. All biochemical findings were nonspecific except elevated erythrocyte sedimentation rate (127 nimHr) Biopsy with histopathology revealed malignant mesenchymal tumor of smooth muscle cell origin (Leiomyosarcoma). Surgical treatment was not indicated, and palliative radiotherapy was recommended.

The knee arthrography is a rather simple, not operative procedure and frequently helpful to the orthopedic surgeon. Although arthrography of the knee was first performed near the turn of the century, it has not yet to gain acceptance and popularity of other radiographic contrast study in this countary. Since 1967, author have performed 182 knee arthrograms in 176 patients of internal derangements of the knee. The 182 knees of the 176 patients had surgical operations on knees and the diagnosis was confirmed surgically. The patients were from 17 year to 46 year of the age and 147 males, 29 females in sex distributions. Author used about 50~90ml. of air as contrast in pneumoarthrography and 15~20ml. of 60% urografin (or Conray 400) in single positive contrast arthrography in knees. For double contrast knee arthrography author used 9~15ml. of 60% urografin (or Conray 400) and 50~90ml. of air as contrast material. The 182 total knee arthrographies were compowed of 28 pneumoarthrographies, 99single positive contrast arthrographies and 55 double contrast arthrographies. The total 182 knees in 176 patients were operated and the diagnosis was confirmed surgically. And comparing with arthrography was performed. The meniscus tears were noted in 114 knees and ligaments tears were in 76 knees in surgical diagnosis. There were 3 Baker's cyst and one intercondyle cmminence fracture. So 18 knees had double lesions at least. The medial meniscus tears were 38 knees and lateral side were 76 knees. Higher incidence of meniscus tears in lateral side is characteristic in my study, compared to Westerns where usually higher incidence in medial side of the meniscus. There were totally 10 false negative and 6 false positive interpretations of the arthrography in 120 meniscus tears after menisectomy. So the error was 13.3% in meniscus tear, and the accuracy of the arthrography in meniscus tear was 86.7% totally. The accuracy in medial meniscus tears was 92.3% and in lateral meniscus tears was 84.0%. Much difficulty and trouble-some were noted in lateral meniscus lesion's interpretations. The accuracy was highest in double contrast knee arthrography(89.7%) and lowest in pneumoarthrography(78%) in meniscus lesions detections. The accuracy of the single positive knee arthrography in meniscus lesions was 88.6%. The most ferquent type of meniscus tear wes oblique type (36.7%). The medial collateral ligaments took tears most frequently. There were no signific ant complications or side reactions during this study, except slight pain and fulling sense. The knee arthrography can be used as screening test for internal derangements of the knee in Korea.

腹部腫瘍(72例)에 있어서의 血管撮影 및 手術所見

河海求,崔斗石,金基延 최신의학사 1973 最新醫學 Vol.16 No.7

Aortography with selective visceral injections has been recognized as highly diagnostic and easy technique for the evaluation of various abdominal mass lesions. At department of Radiology, National Medical Center, Seoul, Korea seventy-two (72) patients whose chief complaints were slowly growing abdominal mass were studied with angiography after conventional examinations (barium study, I. V. P. etc) for last several years(1965-1972). The angiographic patterns were comprehensively analized. Almost cases (about 64 cases) were retroperitoneal expanding lesions which were not well detected with conventional radiological study (barium study, I. V. P. etc). The all expanding lesions were composed of renal expanding lesions(42 cases), other retroperitoneal expanding lesions (17cases), and liver, spleen, pancreatic lesions (13 cases). The angiography with selective visceral injections was the most diagnostic and easy technique without any permament complication than any other conventional studies.

Carotid Body Tumor (Chemodectoma)의 1예

하해구 대한영상의학회 1975 대한영상의학회지 Vol.11 No.1

A case of the carotid body tumor is reported. The patient is a 29 year old Korean women whose chief complaint on admission is about a hen egg sized mass in right lateral portion of the neck just below the mandible angle that is well defined, smooth surfaced, movable and slowly growing for last 5 years. Right carotid arteriography reveals typical well defined tumor staining around the bifurcation area with widening and encircling of the angle between internal and external carotid arteries. (Fig. 2,3 and 4) Other laboratory study and physical examinations are non-specific. The patient rejected surgical operation and discharged after 1 week admission.

During one year (from july, 1979 to June 1980) about 2000 partients have passed through the computed tomography room of han-Yang University Hospital, in Seoul, Korea. In these patients, 300 patients films that were interpretated as normal limits radiographically, and that were over 20 years of the age, were taken at random. These scans were performed as a screening test in patient with minimal, vagueneurologic manifestations such as headache, dizziness, convulsion and depression or suffering the traffic accident, but clinical survey was not performed. Thefollowing indices were surveyed. a) Ventriculo-Cephalic Ratio(V.C.R.)(%) b) Skull Breadth(c) c) The calcification incidence (%) of the pineal gland. The V.C.R. is defined as; minium bicaudate diameter (a) --------------------------------------------------------------- The inner diameter of the skull at the same levle(b) The skull breadth (c) is widest inner diameter of the skull vault. The calcified pineal gland is defined as whiteness in film. The following results were taken 1) The V.C.R.(%) of 300 adults were 14.1±2.5(%) in males, 13.2±2.6(%) in females, 13.7±2.6(%) in total, so the V.C.R. was higher in male. 2) The minium bicaudate diameter (M.B.D.) (a) were 16.8±2.9mm in male 14.5±2.3mm in females, 15.86±2.8mm in total. The M.B.D. was increased in oldeer age, and narrowed in female than male. 3) The brain breadth (c) has narrower one in old age, but the male has wider breadth than female. The btain bteadth (c) was 160.2±6.9 mm in male, 144.2±6.3mm in female, 147.8±6.5mm in total. The female has narrower brain breadth than male with 6.0mm difference. 4) The incidence of the pineal gland calcification(whiteness) was 34.8% in males, 22.4% in female, 30% in total. Higher incidence (12.4%) was noted in male. Totally lpwer incidence was suggested in Koreans than westerns.

The materials are 50 sialographies in 50 patients of the National Medical Center for last 5 years (1968-1973) and 50 normal parotid sialographies in 26 patients of 57 Evacuation (army) Hospital for last several months (1974.5 -1974.10) in Korea. Total is 100 sialographies in 76 patients. The patients in army hospital were selected at random for normal study, but the patients with past or present disease history on salivary glands were excluded. The method is hydrostatic (70-100cm H2O) or manual with catheterization (1.60 polyethylene catheter) and 60% urografin 1-3ml as contrast. The target-film and skin-film distances are 70cm and 3cm. 84% (42 cases) of 50 N. M. C. cases were positive findings radiographically. The contents of these are 17 chronic non-specfic inflammations (parotid 9, submax. 8), 17 neoplasms (parotid 15, submax. 2), and 8 stones (submax. 5, suling. 3). Mixed tumors (8 cases) are highest incndence in neoplasms (17 cases), (table 3, 4, 5). The measurements of he 50 normal parotid sialographies in 26 patients of the 57 Evacuation (army) Hospital revealed main duct diameter(a) 1.06$\pm$0.11 (standard deviation) mm, duct length (1) 5.64$\pm$0.61cm, lateral displacement of the duct(d) from mandible ramus in straight P-A view 1.27$\pm$0.32cm, number of first branches of the main duct(br.) 7.6$\pm$1.9br., and gland dimensions of anteroposterior(w) 4.94$\pm$0.99cm, superoinferior(h) 4.75$\pm$0.72cm, medialolateral(w') 3.30$\pm$0.79cm. (table 6). Parenchymal lesions were better picture with distention slalographies and ducts lesions were better pictures with hydrostatic sialographies. During or after the examinations non-significant complications were noted.
