간암의 정맥계 침범은 흔하나 심장 침범은 드물고 예후가 불량할 뿐 아니라 급사의 위험이 있다. 본 증례처럼 간세포암이 혈관계를 통해 우심방까지 전이된 경우 노작성 호흡곤란 같은 심부전에 의한 증상을 나타낼 수 있어서 간세포암의 간외 전이를 의심하기는 쉽지 않고, 원발 병소를 찾기 위해서 여러 가지 진단적 검사를 시행하여야 한다. F-18 FDG PET/CT는 기능적으로 암세포의 당대사 항진을 3차원적인 입체 영상으로 국소화하기 때문에 비침습적이며 경제적으로 간세포암의 침범 및 간외전이를 쉽게 확인할 수 있다. 저자들은 호흡곤란을 주소로 내원한 55세 남자 환자에서 PET/CT를 통해서 간세포암과 간세포암의 우심방 침범을 진단하는데 도움을 받았기에 이를 문헌고찰과 함께 보고하는 바이다.

Experiment was conducted on the image quality and exposure dose following replacement of $CaWO_4$ system screen BH-III and BX-III which have so far been used for high-voltage hard-radiation quality radiography, with rare earth system screen KO750, combined with high contrast film SRH, while additional filter was altered, Cu 0.8 mm+Al 1.4 mm(HVL : Al 8.8 mm), Cu 1.3 mm+Al 1.0 mm(HVL : Al 10.6 mm) and Cu 1.8 mm+Al 1.5 mm(HVL : Al 11.4 mm). AS a result, visual evaluation did not detect extreme changes in image quality under the respective condition(HVL : $Al\;8.8\;mm{\sim}Al\;11.4\;mm$). It was noted, however, that surface exposure dose declined with an increase in the thickness of the additional filter, as it was $18.9\;{\mu}Gy$ at HVL Al 8.8 mm, $17.5\;{\mu}Gy$ at Al 10.6 mm and $15.7\;{\mu}Gy$ at Al 11.4 mm. Considering the limited rating of X-ray equipment and wear of machinery, however, the range of $Cu\;1.3\;mm{\sim}1.8\;mm+Al\;1.0\;mm{\sim}1.5\;mm(1/16\;VL{\sim}1/32\;VL)$ seemed to be a limit.

The recent development of cardiovascular surgery as well as aortoarteriogaphy has been established excellent operative result with great aid of limb-salvage. However, less consideration or less experience still exists on the regard of vascular accident and vascular disease, as well as vascular surgery in Korea. During the last 13 years, we experienced only two cases of aorto-iliac occlusion,acute and chronic, regardless of having had more than 300 cases of mitral valvotomy and gradual increasing tendency of arteriosclerosis and hypertension in Korea. Therefore it is noteworthy to report the cases in order to promote the consideration for vascular surgery. Case 1; 52 year old female who had 20 years history of mitral stenosis with uricular fibrillation and received medical treatment for recent 1 year in the medical department. 10 days before admission, acute saddle emboli developed and 15 days after the onset, embolectomy through both common femoral arteries on the groin and abdominal approach was made. The progression of emboll to the right popliteal bifurcation was found by arteriography on operating table and retrograde flushing with heparin solution by the polyethylene catheter inserted through posterior tibial artery. The operation was successful, but 9 hours after operation sudden death occurred. Considering this case, first, mitral valvotomy already before might prevent peripheral embolizatlon, secondarily, the more early detection and surgery might also prevent the progression of emboli. Thirdly, although preoperative or postoperatlve heparinization is controversial for mitraI stenosis, heparinization might prevent additional emboli to vital organs in this case Cases 2; 66 year old female who had 4 years history of left hip and calf intermittent claudication and has had rest pain, inability to walk and ischemic necrosis on the the left leg since last 3 months prior to admission to the orthopedic department under the suspicion of herniated disc. Absence of pulsation on the groin and aortography evidenced aortoillac occlusion predominantly on the left side. Thromboendarterectomy was made and the operative result was successful with absence of claudication, healing of ulcer and aortographic patency of occlusive site. This chronic occlusion is considered to result from arteriosclerosis in origin with the evidence of moderate hypertension, x-ray evidence of calcified plaque on the aortic knob and operative finding of palpable plaques.

Poncet's disease is an aseptic polyarthritis developing in the presence of active Tuberculosis occurring elsewhere, and is not due to direct involvement of joints but to an immunological reaction to tuberculoprotein. We experienced a case of Poncet's disease accompanying erythema nodosum in a 55-year-old female patient with pulmonary tuberculosis. She had multiple tender erythematous nodules on both lower limbs for 3 months and a cough and sputum from one month ago. She felt severe pain in both knees and ankles with swelling one week before admission. Her chest X-ray, computed tomography (CT) scan and positive sputum AFB stain results revealed that she had active pulmonary tuberculosis accompanying erythema nodosum and aseptic polyarthritis. Her arthritis and erythema nodosum were dramatically improved within four weeks after anti-tuberculosis therapy. We report a case of Poncet's disease in pulmonary tuberculosis accompanying erythema nodosum.

Mycoplasma pneumoniae에 의한 폐렴의 임상양상은 다양하다고 알려져 있으며, 흉부 방사선 소견상 대부분 기관지 주위 폐렴이나 반점형 폐 침윤 양상을 보이고 폐허탈은 5% 정도로 매우 드물게 발생하는 것으로 되어 있다. 본 저자들은 미열, 두통, 건성 기침, 근육통 등 비정형적인 폐렴의 증상을 보이면서 대엽성 무기 폐로 발현한, 마이코플라즈마 폐렴을 경험하였기에 이를 보고하는 바이다.

박리성 간질성 폐렴은 흡연가에 호발하는 비교적 드문 미만성 간질성 폐질환이다. 박리성 간질성 폐렴은 치료에 대한 반응과 예후가 좋은 질환이나, 재발하는 경우가 있고 치료기간이 명확히 정해져 있지 않으며, 심한 섬유화가 동반되는 경우는 드문 질환이다. 저자들은 흉부 전산화단층 촬영에서 견인성 기관지확장증과 초기의 벌집모양 폐 소견과 함께 미만성 간유리혼탁화를 보이는 환자에서 흉강경하 폐 조직 검사로 박리성 간질성 폐렴을 진단하였고, 치료 종결 후 재발한 박리성 간질성 폐렴을 경험하였기에 이를 보고하는 바이다.

흉선암종은 드문 종격동의 악성 종양으로서 흉선상피세포에서 기원하지만 흉선종과는 조직학적 특징이 다르다. 흉선종이 자가면역질환을 종종 동반하는데 반해 흉선암종에서 자가면역질환이 동반되는 예는 드물다. 국내에서는 흉선암종과 자가면역질환이 동반된 예가 보고된 적이 없는데 저자들은 전신 근육통을 주소로 내원한 49세 남자 환자가 전신홍반루프스와 흉선암종을 동시에 진단받고 항암치료를 시작한 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

Background: Eosinophilia is well recognized in specific conditions. The objective of the present study was to determine clinico-radiologic characteristics of eosinophilia and changes in prevalence over 10 years in recipients of private health screening program at a tertiary hospital in Korea. Methods: Data of private health screening program recipients at the health promotion center of Chung-Ang University Hospital from 2004 to 2013 were collected. Health-related questionnaires and laboratory findings of private health screening program with possible relation with eosinophilia were reviewed. Results of enzyme-linked immunosorbent assay (ELISA) for parasite, chest computed tomography, and pulmonary function test were also reviewed. Results: The cumulative prevalence of eosinophilia was 4.0% (1,963 of 48,928). Prevalence of eosinophilia showed a decreased trend from 2004 to 2013. Most cases (96.6%) had mild degree of eosinophilia. Eosinophilic subjects were older and male-predominant. They showed lower levels of forced expiratory volume in 1 second ($FEV_1%$), forced vital capacity (FVC%), and $FEV_1/FVC$ than those without eosinophilia. Eosinophilic subjects showed higher positive rate for common parasite in ELISA than those without eosinophilia. On radiologic findings, consolidation and ground glass opacities were positively associated with the degree of eosinophilia. When eosinophil was classified based on severity, statistically significant correlation between the severity of eosinophil and radiologic abnormalities was found. Conclusion: Eosinophilia is uncommon in healthy population. It usually occurs at a mild degree. Eosinophilic patients have more radiologic abnormalities compared to those without eosinophilia. Such radiologic abnormalities are associated with the severity of eosinophilia.

During the mobile clinic activities in Tak Province, Thailand, Paragonimus sp. eggs were found in a fecal sample of a 72-year-old Karen resident. Paragonimus DNA was amplified from the stool sample and identified to P. heterotremus. The patient did not have any symptoms. Apparent pulmonary lesion was not found on the chest X-ray. The patient admitted habitual consumption of semi-cooked or roasted waterfall crabs for several years. The waterfall crabs collected from stream near the village were found negative for Paragonimus metacercariae. In northern Thailand, paragonimiasis remains as one of the public health concerns and should be ruled out for asymptomatic pulmonary patients.
