The role of magnetic resonance(MR) imaging in the evaluation of thoracic disease has been limited Nontheless, MR has inherent properties of better contrast resolution than CT allowing tissue-specific diagnosis. MR has capability of direct imaging in sagittal, coronal, and oblique planes which provide better anatomic information than axial images of CT such as lesions in the pulmonary apex, aorticopulmonary window, peridiaphragmatic region, and subcarinal region. MR is sensitive to blood flow making it an ideal imaging modality for the evaluation of cardiovascular system of the thorax without the need for intravenous contrast media. Technical developments and better control of motion artifacts have resulted in improved image quality, and clinical applications of MR imaging in thoracic diseases have been expanded. Although MR imaging is considered as a problem-solving tool in patients with equivocal CT findings, MR should be used as the primary imaging modality in the following situations: 1) Evaluation of the cardiovascular abnormalities of the thorax 2) Evaluation of the superior sulcus tumors 3) Evaluation of the chest wall invasion or mediastinal invasion by tumor 4) Evaluation of the posterior mediastinal mass, especially neurogenic tumor 5) Differentiation of fibrosis and residual or recurrent tumor, especially in lymphoma 6) Evaluation of brachial plexopathy With technical developments and fast scan capabilities, clinical indications for MR imaging in thorax will increase in the area of pulmonary parenchymal and pulmonary vascular imaging.

연구배경 : 많은 외상 환자에서 흉곽골이 손상에 노출되지만 흉곽골 외상 환자에서 단순 흉부 사진으로 흉곽부위 손상정도를 최종진단 하기는 어려운 경우가 많다. 특별히 흉곽골의 경미한 손상의 경우는 골주사 검사를 사용하여 명확한 진단을 할 수 있겠는데 감수성은 매우 높은 결과를 나타내었다. 재료 및 방법 : 680명의 흉곽 외상환자 중 골스캔을 환자를 대상으로 조사하였다. 결과 : 680례에서 감수성은 97.4%이고 위음성은 2.6%였다. 감수성에 있어서 검사 실시 시기가 가장 중요한 요소로 생각되며 손상 부위별로 늑골이나 흉골 골절의 경우는 1주 이후, 늑연골 접합부골절의 경우와 상기 부위골절들이 동반된 경우는 3일 이후면 언제나 우수한 결과를 보였다. 결론 : 흉부외상환자에서 골절에 대한 정확한 진단을 위하여는 적절한 시기의 골스캔이 필요하다.

A 7-year-old intact female Maltese dog presented with a history of bite wounds. Physical examination revealed labored breathing, four puncture wounds with subcutaneous emphysema of the thorax, and paradoxical respiratory movement of the right thoracic wall. On radiography, a segmental fracture of the right 7th rib and a single fracture of the 8th rib were evident on the dorsal thorax. An inward displacement of the fractured segment and contusion of the right caudal lung lobe were identified with computed tomography. A diagnosis of pseudo-flail chest was made. Exploratory thoracotomy revealed a full-thickness muscular defect, a marked discoloration of the right caudal lung lobe, a segmental fracture of the right 7th rib, and a single fracture of the right 8th rib. Necrotic tissues were removed using surgical debridement. The fractured 7th and 8th ribs were corrected using a single interfragmentary wiring technique. The thoracic wall was reconstructed using the latissimus dorsi muscle flap. Additional thoracic stabilization using a thermoplastic splint was applied to correct paradoxical respiratory movement. The external splint was removed 4 weeks postoperatively. There was no evidence of respiratory abnormalities 18 months postoperatively.

Angiomatosis [ or Diffuse Hemangima] is a rare condition in which large segments of the body are involved by proliferating vessels. By now, some authers say that this lesion begins during early intrauterine life when the limb buds form, grow proportionately with the fetus, and consequently affect large areas of the trunk or extremity. The majority of angiomatoses present during childhood or infancy as swelling, induration, or discoloration of the affected area. The patient was 13 year old male and had no specific signs and symptoms except palpable mass on the left lateral chest wall from childhood and a painful tender mass on the posterior chest wall for 5 days before admission. The chest PA showed no abnormalities.The operation was done with the resection of left 10th rib and 9th and 10th intercostal muscles including masses and the ligation of the both intercostal and feeding vessels of the masses. The pathologic result was angiomatosis involving intercostal muscles and rib.

A recently recognized connective tissue disorder, Loeys-Dietz syndrome (LDS) is a genetic aortic aneurysm syndrome caused by mutations in the transforming growth factor-receptor type I or II gene (TGFBR1 or TGFBR2). They have distinctive phenotypic abnormalities including widely spaced eyes (hypertelorism), bifid uvula or cleft palate, and arterial tortuosity with aortic aneurysm or dissection throughout the arterial tree. LDS is characterized by aggressive and rapid progression of aortic aneurysm. Therefore, the patients with distinct phenotype, marked aortic dilatation and aneurysm at early age should be suspected to be affected by LDS and rapid TGFBR gene analysis should be done. We report one child diagnosed as LDS due to typical phenotypes and two novel missense mutations of the TGFBR2 gene (c.1526G>T and c.1528A>T).

In pediatric thoracic CT, respiratory motion is generally treated as a motion artifact degrading the image quality. Conversely, respiratory motion in the thorax can be used to answer important clinical questions, that cannot be assessed adequately via conventional static thoracic CT, by utilizing four-dimensional (4D) CT. However, clinical experiences of 4D thoracic CT are quite limited. In order to use 4D thoracic CT properly, imagers should understand imaging techniques, radiation dose optimization methods, and normal as well as typical abnormal imaging appearances. In this article, the imaging techniques of pediatric thoracic 4D CT are reviewed with an emphasis on radiation dose. In addition, several clinical applications of pediatric 4D thoracic CT are addressed in various thoracic functional abnormalities, including upper airway obstruction, tracheobronchomalacia, pulmonary air trapping, abnormal diaphragmatic motion, and tumor invasion. One may further explore the clinical usefulness of 4D thoracic CT in free-breathing children, which can enrich one's clinical practice.

In 1835,Schlesinger first described a case of subisthmlc lower thoracic aortic coarctation. Since Olim`s unsuccessful reconstructive surgery in 1949 and Beattie`s first successful resection with homograft replacement on such a lesion in 1951 were reported,about 20 cases of atypical aortic coarctation had been treated by definitive surgery until 1964. In Korea, only 2 cases of atypical aortic coarctation treated by bypass graft were reported until now. This is the third case-report treated by reconstructive surgery. The patient,11 year old girl who had 2 year history of headache, visual weakness, intermittent claudlcation, and general weakness, was first diagnosed of having the hypertension due to atypical coarctation by the findings of high blood pressure[170/110mmHg] at the upper extremity and weak pulsation on both femoral artery,murmur on the epigastrium, absence of aortic knob, and aorto graphy. Aortography demonstrated the isolated segmental narrowing[length 5cm, diameter 0.4cm] at the level of aortic hiatus 2cm above celiac arterial origin, the dilated right 9th, 10th, 11th intercostal arteries with multiple dimunitive collaterals and no associated abnormalities in the other arteries. Preoperatlve positive findings were strong positive mantoux test, high AST[720 units]. transient mild cardiomegaly with right lung infiltration on chest X-ray and suggestive left ventricular hypertrophy on ECG. On December 1970, through separate left thoracotomy and abdominal approach, bypass graft between descending thoracic aorta and abdominal aorta below renal artery was performed. The operation was first successful with satisfactory reduction of hypertension on the upper trunk[postoperatlve 130/80mmHg] and strong pulsation on the lower extremities[postop. O, postop. 140/100mmHg]. However,6 weeks after surgery, she expired of sudden hemoptysis and shock due to anastomotic leak within the thorax. Operative finding disclosed that the affected aorta was firm, with rich periaortic fibrosis and the outer diameter of stenotic site was not attenuated. Histopathology of the resected specimen was also compatible with primary arteritis.

배 경 : 결핵성 흉벽 농양은 결핵의 드문 합병증이다. 결핵성 흉벽 농양은 다양한 병인에 따라 CT 소견에 차이가 있을 것으로 생각되며 이러한 차이를 밝히는 것이 결핵성 흉벽농양의 진단 뿐만 병인을 이해하는 것에도 도움이 될 것으로 생각된다. 대상 및 방법 : 결핵성 농양으로 확진된 20명의 환자를 대상으로 하였다. 20명 환자의 29개 농양을 활동성 폐실질 혹은 흉막 병변의 유무와 이들 병변과 농양의 접촉 여부에 따라 3가지 유형으로 분류하였다. l형은 폐실질 또는 흉막에 활동성 결핵성 병변이 없는 경우로, 2형은 활동성 폐결핵이나 흉막병변이 흉벽농양과 접하고 있는 경우로, 3형은 폐결핵이나 흉막병변이 있으나 농양과 접하고 있지 않는 경우로 각각 정의하였다. CT 유형에 따른 농양의 크기, 모양 및 위치 등의 차이를 분석하였다. 결 과 : l형에는 6명 환자의 6개의 농양이 속하였다. 이틀 농양은 늑골이나 늑연골의 파괴를 동반하며, 이것을 중심으로 크기가 크고 비교적 구형에 가까운 모양이었다. 2형은 10명 환자의 13개의 농양이 속하였다. 흉막 병변과 접하고 있는 7예와 종격동 림프절염과 접하고 있는 1예는 농양의 중심이 외근육층에 있고, 상하 길이가 긴 타원형의 모양이었다. 폐실질 병변과 접하고 있던 5예는 농양의 중심이 흉막외공간에 있고 크기가 작고 횡축이 긴 타원형이었다. 3형에는 6명 환자에서 10개의 농양이 속하였다. 이것들은 주로 흉막외공간에 생기며 크기가 작고 늑골의 장축을 따라 횡측의 길이가 긴 타원의 모양이고, 다발성의 빈도가 높았다. 결 론 : 결핵성 흉벽 농양은 농양의 모양과 동반된 폐실질 및 흉막 병변에 따라 몇개의 유형으로 나눌 수 있었다. 이러한, 유형의 차이는 다양한 병인에 따른 것으로 추정되며, 결핵성 흉벽 농양의 다양한 형태를 이해하는 것 이 진단 뿐만 아니라 병인을 이해하는데 도움이 될 것으로 생각된다. CT는 결핵성 농양의 진단 뿐만 아니라 농양의 범위, 동반된 폐실질및 흉막병변을 보는데 유용하다.
