Lemierre syndrome is a rare disease characterized by internal jugular vein thrombosis and septic emboli, and it primarily occurs in healthy young individuals; this disease usually follows an acute oropharyngeal infection. To the best of our knowledge, only a few reports about this disease have appeared in the radiologic literature. We report here the radiologic findings of a case of Lemierre syndrome in a young healthy female adolescent who had a history of acute haryngotonsilitis. Chest radiographs showed lung nodules that displayed cavitary changes with rapid progression on the serial studies. High-resolution CT scan showed multi-focal patchy consolidations that connect with vessels, and this was suggestive of septic pulmonary embolism. Ultrasonography and CT scan of the neck revealed right internal jugular vein thrombosis. 르미에르 증후군은 젊은 성인에서 급성 구인두 감염 이후에 내경정맥 혈전과 패혈성 폐색전증을 특징으로 하는 드문 질환으로 이 질환에 대한 보고가 많지 않다. 저자들은 급성 편도선염을 앓고 있던 16세 여자환자에서 발생한 르미에르 증후군의 방사선학적 소견을 보고하고자 한다. 단순흉부촬영상 빠르게 진행하는 공동화를 보이는 결절들을 볼 수 있었고 HRCT에서는 패혈성 폐색전증을 시사하는 혈관과 연결된 다병소의 반점형 폐경화의 소견이 관찰되었다. 경부 초음파와 두부 CT 검사에서는 내경정맥 혈전이 보였다.

Cystic adventitial disease of the popliteal artery is rare condition, but it is an important cause of peripheral vascular insufficiency in young men. Conventional angiography or MR imaging has traditionally been considered as the study of choice to diagnose this disease. We experienced a case of cystic adventitial disease of the popliteal artery that was diagnosed by 16-slice MDCT angiography, and this imaging modality displayed an accurate diagnostic capability for this disease. 슬와동맥의 cystic adventitial disease는 드문 질환으로 젊은 남성의 말초 혈관 부전의 중요한 원인이다. 전통적으로 고식적 혈관조영술이나 MR영상이 영상진단의 표준이지만 저자들은 16-slice MDCT로 영상진단이 가능하였던 슬와동맥의 cystic adventitial disease를 경험하였기에 이를 보고하고자 한다.

The detailed kinetics of the cytomegalovirus (CMV)-specific T cell response in hematopoietic stem cell transplant (HCT) recipients have not yet been fully assessed. We evaluated these kinetics of CMV-specific T cell response and factors associated with high CMV-specific T cell responses 1 year after HCT. In HCT recipients, CMV pp65 and IE1-specific ELISPOT assay were performed before HCT (D0), and at 30 (D30), 90 (D90), 180 (D180), and 360 (D360) days after HCT. Of the 51 HCT recipients with donor-positive (D+)/recipient-positive (R+) serology, 26 (51%) developed CMV infections after HCT. The patterns of post-transplantation reconstitution for CMV-specific T cell response were classified into 4 types: 1) an initial decrease at D30 followed by gradual T cell reconstitution without CMV infection (35%), 2) an initial decrease at D30 followed by gradual T cell reconstitution preceded by CMV infection (35%), 3) failure of gradual or constant T cell reconstitution (26%), and 4) no significant T cell reconstitution (4%). There was no significant difference between ELISPOT counts of D360 and those of D0. High CMV-specific T cell responses at D360 were not associated with high CMV-specific T cell response at D0, CMV infection, ganciclovir therapy, graft versus host disease (GVHD), and immunosuppressant use. In conclusion, there are 4 distinct patterns of reconstitution of the CMV-specific T cell response after HCT. In addition, reconstituted donor-origin CMV-specific T cell responses appeared to be constant until day 360 after HCT, regardless of the level of the pre-transplant CMV-specific T cell response, CMV infection, and immunosuppressant use.

Undifferentiated pleomorphic sarcoma (UPS) arising from the descending thoracic aorta is a rare type of tumor. To our knowledge, only a few cases have been reported in the literature. We present computed tomography (CT) and magnetic resonance imaging findings of a 43-year-old male patient with undifferentiated pleomorphic sarcoma of the descending thoracic aorta, which showed enhancement on only magnetic resonance imaging (MRI). MRI with contrast enhancement may be useful in differentiating an aortic tumor from atherosclerotic disease.
Pulmonary Adenofibroma Manifesting as Two Nodules in Different Lobes of the Lung: A Case Report
김민수,배영아,변선주,최정아 대한영상의학회 2020 대한영상의학회지 Vol.81 No.2
Pulmonary adenofibroma is a rare tumor, with a few reported cases in the literature. Radiologically, the lesion appears as a solitary pulmonary nodule in most cases, and the multiplicity of this disease entity is extremely rare. We present an unusual case of pulmonary adenofibroma in a 71-year-old woman manifested as two nodules in different lobes of the lung on CT. Histopathological and immunohistochemical examinations are needed to establish the definitive diagnosis of pulmonary adenofibroma.
Sonographic Appearance of Dermal and Subcutaneous Sarcoidosis: A Case Report
장자윤,배영아,홍혁진,권계원 대한초음파의학회 2012 ULTRASONOGRAPHY Vol.31 No.4
Sarcoidosis is a systemic granulomatous disease of unknown origin that mainly involves lung and skin, but rarely involves subcutaneous tissue. While some studies have reported on CT or MR imaging findings of subcutaneous sarcoidosis, there is only one report on sonographic findings of subcutaneous sarcoidosis, recently published in the US. Familiarity with ultrasonographic findings of subcutaneous sarcoidosis might be helpful for the early diagnosis in patient with palpable nodules and image follow-up for subcutaneous sarcoidosis. Here we report on the sonographic appearance of subcutaneous sarcoidosis involving dermal and subcutaneous tissue over axilla and sole, a case diagnosed as sarcoidosis and improved by steroid treatment,along with a review of the relevant literature.

Supradiaphragmatic liver is a rare condition. Establishing an accurate preoperativediagnosis is difficult. Operative exploration is necessary to differentiate this lesion fromintrathoracic masses, such as a pleural based tumor, diaphragmatic tumor and peripherallung tumor. However, with the aid of the hepatocyte-specific magnetic resonanceimaging contrast agent, gadoxetic acid (Gd-EOB-DTPA), functional hepatocytes in thelesion can be identified in the hepatobiliary phase, potentially allowing an accurate andnon-invasive diagnosis. We report a case of supradiaphragmatic liver diagnosed by Gd-EOB-DTPA-enhanced magnetic resonance imaging.
인플루엔자 바이러스A 감염에 의한 반복적인 급성 호흡곤란 증후군의 발생 증례
김형우,이경주,최성실,배영아 대한내과학회 2015 대한내과학회 추계학술대회 Vol.2015 No.1
서론: 급성 호흡곤란 증후군은 급성의 비심장성 폐부종, 심한 동맥혈 저산소혈증, 흉부 방사선상 양측성 폐침윤이 특징인 질환이며 원인으로 외상, 약물중독, 세균성질환, 바이러스질환 등이 있다. 이중 바이러스에 의한 원인으로 최근에 가장 많은 비율을 차지하는 것은 인플루엔자 바이러스이다. 본 저자는 반복적인인플루엔자 바이러스A에 의한 감염으로 반복적인 급성 호흡곤란 증후군을 보인 증례를 보고하고자 한다. 증례: 39세 남자환자로 내원 7일전부터 발생한 호흡곤란과 발열을 주소로 입원하여 시행한 흉부 전산화 단층촬영에서 양측 폐 전체에 걸쳐있는 간유리음영과 일부 경화성병변이 관찰되었다. 인플루엔자 바이러스A항원 양성소견 이외 다른 배양검사 및 면역관련 검사는 음성이었고 베를린정의상 중증의 급성 호흡곤란 증후군에 부합했다. 항바이러스제재와 기계호흡에도 저산소혈증이 개선되지 않아 체외막 산소화 장치까지 적용했고 이후 흉부 방사선상 병변과 저산소혈증이 호전되어 입원한지 29일만에 퇴원했다. 외래 추적에서 인플루엔자 백신을 접종했으나 1년뒤 2015년 3월에 다시 발열과 호흡곤란을 보이며 인플루엔자 바이러스A항원 양성과 흉부 방사선상 양측성 폐침윤및 흉부 전산화 단층촬영에서 양측 폐에 간유리음영의 병변을 보여 베를린정의상 경도의 급성 호흡곤란 증후군으로 12일간 입원 치료했다. 2015년 4월에도발열과 호흡곤란을 보이며 인플루엔자 바이러스A항원 양성과 경도의 급성 호흡곤란 증후군으로 12일간 입원치료 후 퇴원했다. 고찰: 반복적인 인플루엔자바이러스A에 의한 감염으로 급성 호흡곤란 증후군이 반복 발생한 상기 환자는 처음 보고되는 증례이며 급성 호흡곤란 증후군의 반복적인 발생은 다른 배양검사나 면역관련검사에서 특이점이 없었던 것으로 보아 사이토카인 폭풍과 관련이 있을 것으로 생각된다.
