Transcatheter arterial chemoembolization(TACE) was performed in a 61 year old male patient with hepatocellular carcinoma with 10 cc of Lipiodol and 50 mg of doxorubicin. Three days later, he complained of dyspnea and dry cough. The arterial blood gas study revealed moderate hypoxemia and hypocarbia. The chest PA showed acute pulmonary edema with bilateral pleural effusion. To rule out the possibilities of acute respiratory failure caused by infection, pulmonary embolism or congestive heart failure, we performed several laboratory studies. The blood and sputum culture studies revealed negative results for bacterial growth. The echocardiogram was normal. The abdominal CT scan and MR imaging revealed no thrombus or mass lesion in the inferior vena cava. So we concluded pulmonary oil embolism induced by lipiodol as the cause of acute lung injury. Four weeks later, clinical symptoms and chest x-ray were markedly improved with conservative care. We report a case of acute lung injury after TACE with lipiodol and doxorubicin, with review of literatures.

Lymphangioleiomyomatosis is a rare disease which afflicts young women of childbearing age. We experienced a 32-year-old female who was admitted because of worsening exertional dyspnea after hormonal therapy with Clomifen for five months and intermittent hemoptysis. Chest PA showed diffuse ground glass appearance with some reticular infiltrations. High resolution CT scan showed multiple small thin walled cysts distributed homogeneously throughout the entire lung. Pulmonary function test showed characteristic obstructive pattern despite the restrictive interstitial pattern of chest radiography. Thoracoscopic lung biopsy specimen showed abnormal proliferation of smooth muscle cells in the walls of lymphatic vessels, bronchioles, and pulmonary vessels typical of pulmonary lymphangioleiomyomatosis. Hormonal therapy with medroxyprogesterone was initiated.
A 23-year old woman was admitted to our hospital with hemoptysis. The chest X-ray showed reticulonodular opacity and multiple cysts throughout the entire lung field. The chest CT scan revealed numerous bilateral cysts with various sizes, some of them with thickened walls. An open lung wedge resection was performed. The resected specimen showed scattered small nodules, 0.3 to 0.6 cm in size. Microscopically, each nodule was composed of atypical glands with an occasional papillary architecture spreading to the alveolar septa, which were morphologically consistent with a papillary adenocarcinoma with a bronchioloalveolar carcinoma growth pattern. Immunochemically, the tumor cells were negative for the S-100 protein. The patient was diagnosed with an adenocarcinoma of the lung. A variety of diseases can produce or mimic multiple, thin-walled cysts in the lung. Lung cancer with multiple cysts is quite rare. Nevertheless, adenocarcinoma should be a diagnostic consideration. We report a case of a multiple cystic adenocarcinoma of the lung.

Background: This study aimed to investigate sternal healing over time and the incidence of poor sternal healing in patients undergoing coronary artery bypass graft (CABG) surgery using bilateral internal thoracic arteries. Methods: This study enrolled 197 patients who underwent isolated CABG using skeletonized bilateral internal thoracic arteries (sBITA) from 2006 through 2009. Postoperative computed tomography (CT) angiography was performed on all patients at monthly intervals for three to six months after surgery. In 108 patients, an additional CT study was performed 24 to 48 months after surgery. The axial CT images were used to score sternal fusion at the manubrium, the upper sternum, and the lower sternum. These scores were added to evaluate overall healing: a score of 0 to 1 reflected poor healing, a score of 2 to 4 was defined as fair healing, and a score of 5 to 6 indicated complete healing. Medical records were also retrospectively reviewed to identify perioperative variables associated with poor early sternal healing. Results: Three to six months after surgery, the average total score of sternal healing was $2.07{\pm}1.52$ and 68 patients (34.5%) showed poor healing. Poor healing was most frequently found in the manubrium, which was scored as zero in 72.6% of patients. In multivariate analysis, the factors associated with poor early healing were shorter post-surgery time, older age, diabetes mellitus, and postoperative renal dysfunction. In later CT images, the average sternal healing score improved to $5.88{\pm}0.38$ and complete healing was observed in 98.2% of patients. Conclusion: Complete sternal healing takes more than three months after a median sternotomy for CABG using sBITA. Healing is most delayed in the manubrium.
The purpose of this study is investigation of radiation dose in CT scan. Data were collected from various references and organizations. Doses measured by CT scanners of each medical organization were analyzed and they were calculated through the examination protocol. The results are as follows : 1. $CTDI_W$ value per 100mAs measured by Head Phantom was the highest in <4-slice MDCT scanner> of 24.20 mGy. $CTDI_W$ values were significantly different among scanner generations(p < 0.01). 2. $CTDI_W$ value per 100 mAs measured using body phantom was the highest in <4-slice MDCT scanner> of 13.58 mGy and the $CTDI_W$ values were significantly different among scanner generations(p < 0.01). 3. When contrast medium was not used, the highest scanner was <16 slice MDCT> of $818.83\;mGy{\codt}cm$ in exposure dose in brain scan(p < 0.05). When the contrast medium was used, the highest scanner was <4 slice MDCT> and its average was $1,460.77\;mGy{\cdot}cm$(p < 0.1). 4. When the contrast medium was not used, the highest scanner was <16-slice MDCT> of $521.63\;mGy{\cdot}cm$ on average in terms of the exposure dose in chest inspection(p<0.05). when the contrast medium was used, the highest scanner was found in 8 slice MDCT scanner and its average was $1,174.70\;mGy{\cdot}cm$. There was no statistically significant difference among scanners. 5. When the contrast medium was not used, the highest scanner was <16-slice MDCT> and its average was $856.27\;mGy{\cdot}cm$ in exposure dose on the abdomen-pelvis(p<0.05). when the contrast medium was used, the highest scanner was <16-slice MDCT> and its average was $1,720.64\;mGy{\cdot}cm$ on average (p < 0.05). 6. When the contrast medium was not used, the highest scanner was <8-slice MDCT> and its average was $612.07\;mGy{\cdot}cm$ in exposure dose in liver inspection(p < 0.05). when the contrast medium was used, the highest scanner was <8-slice MDCT scanner> and its average was $2,197.93\;mGy{\cdot}cm$ in exposure dose(p < 0.1). seventy six point two percent of medical facilities were in risk of radiation exposure while the number of phase was three to four times in their dose inspection of contrast medium.

Objective : Unclear mental state is one of the major factors contributing to diagnostic failure of occult skeletal trauma in patients with traumatic brain injury (TBI). The aim of this study was to evaluate the overlooked co-occurring skeletal trauma through whole body bone scan (WBBS) in TBI. Methods : A retrospective study of 547 TBI patients admitted between 2015 and 2017 was performed to investigate their cooccurring skeletal injuries detected by WBBS. The patients were divided into three groups based on the timing of suspecting skeletal trauma confirmed : 1) before WBBS (pre-WBBS); 2) after the routine WBBS (post-WBBS) with good mental state and no initial musculoskeletal complaints; and 3) after the routine WBBS with poor mental state (poor MS). The skeletal trauma detected by WBBS was classified into six skeletal categories : spine, upper and lower extremities, pelvis, chest wall, and clavicles. The skeletal injuries identified by WBBS were confirmed to be simple contusion or fractures by other imaging modalities such as X-ray or computed tomography (CT) scans. Of the six categorizations of skeletal trauma detected as hot uptake lesions in WBBS, the lesions of spine, upper and lower extremities were further statistically analyzed to calculate the incidence rates of actual fractures (AF) and actual surgery (AS) cases over the total number of hot uptake lesions in WBBS. Results : Of 547 patients with TBI, 112 patients (20.4 %) were presented with TBI alone. Four hundred and thirty-five patients with TBI had co-occurring skeletal injuries confirmed by WBBS. The incidences were as follows : chest wall (27.4%), spine (22.9%), lower extremities (20.2%), upper extremities (13.5%), pelvis (9.4%), and clavicles (6.3%). It is notable that relatively larger number of positive hot uptakes were observed in the groups of post-WBBS and poor MS. The percentage of post-WBBS group over the total hot uptake lesions in upper and lower extremities, and spines were 51.0%, 43.8%, and 41.7%, respectively, while their percentages of AS were 2.73%, 1.1%, and 0%, respectively. The percentages of poor MS group in the upper and lower extremities, and spines were 10.4%, 17.4%, and 7.8%, respectively, while their percentages of AS were 26.7%, 14.2%, and 11.1%, respectively. There was a statistical difference in the percentage of AS between the groups of post-WBBS and poor MS (p=0.000). Conclusion : WBBS is a potential diagnostic tool in understanding the skeletal conditions of patients with head injuries which may be undetected during the initial assessment.
Silicone fluid(polydimethylsiloxane) is widely used in breast augmentation and other cosmetic procedures because of little incidence of complications and low mortality rate. However, local reaction following silicone injections can be occurred sometimes leading to serious complications. Especially, illicit silicone injections have resulted in severe reactions within the pulmonary area, and some have resulted in acute respiratory distress syndrome subsequently. We experienced a case of acute respiratory distress syndrome induced by subcutaneous injections of silicone at vaginal wall. The patients was 39-year-old, previously healthy woman who had complained of dyspnea related to silicone injection at vaginal wall. Chest X-ray and chest CT scan show diffuse air consolidation with ground glass opacities and perfusion lung scan revealed likelihood of pulmonary embolism as showing multiple perfusion defects. We report a case of acute respiratory distress syndrome occured after silicone injection with review of literature.
Background: As well as fiberoptic bronchoscopy, chest computerized tomographic scan can now differentiate the benign from malignant causes and the obstructive from non-obstructive causes of lung collapse. This study was designed to evaluate the usefulness of chest CT scan and fiberoptic bronchoscopy in the diagnosis of middle lobe syndrome. Method: We reviewed the clinical features, roentgenographic changes, pathologic findings and bronchoscopic findings in 16 patients with middle lobe syndrome who were admitted to Severance Hospital during period of January, 1987 through January, 1992. Results: The male to female ratio was 1:1. The most common symptoms were cough and sputums. Crackle was the most common physical finding. Underlying disease was lung cancer, pulmonary tuberculosis and endobronchial tuberculosis in 3 each other, benign stenosis in 2, lung abscess, broncholithiasis, bronchial chondroma, pneumonia and nonspecific inflammation in 1 each other. Conclusion: We conclude that the combination of chest computerized tomogram and fiberoptic bronchoscopy was most desirable for the diagnosis of middle lobe syndrome.

Empyema necessitatis refers to empyema that extends into the extrapleural space through a defect in the pleural surface. Tuberculous empyema necessitatis is a rare complication of tuberculosis. We experienced a 21-month-old boy with tuberculous empyema necessitatis with osteomyelitis in the right $7^{th}$ rib. He presented with a mass on the right lateral chest wall, which was soft and nontender, enlarging for one month. He also had mild fever. The plain radiograph of his chest revealed soft tissue swelling and calcified lymph node on the left axilla, and his PPD skin test was positive. CT scan of the chest showed empyema necessitatis at the right lower chest and upper abdominal walls with osteomyelitis of the right $7^{th}$ rib. He did not have concurrent pulmonary tuberculosis. Surgery was performed for diagnosis and treatment. In histopathologic findings, chronic granulomatous inflammation with caseation necrosis was shown and was positive for acid fast bacilli stain. In addition, M. tuberculosis complex was found as etiology by polymerase chain reaction. The patient has been treated with anti-tuberculous medication without any specific complication.
A 70-year-old female who was diagnosed as myxoid chondrosarcoma by fine needle aspiration of a pleural mass is described. She presented with left chest discomfort of 4 months' duration and aggravating dyspnea and chest pain for 2 months. Chest X-ray and CT scan revealed a large lobulated low density mass invading chest wall at the left pleural cavity and massive pleural fluid. Fine needle aspiration was done under the impression of mesothelioma or metastatic cancer. The aspirates from the mass were very cellular and composed of isolated or clustered forms of large plump cells. Abundant cytoplasm was blulsh opaque and the margin was rounded in the isolated cells, whereas clustered cells show ill-defined ceil borders and aggregating tendency. The nuclei were eccentric, round to ovoid, and had fine chromatin pattern and multiple small nucleoli. Cellular pleomorphism or mitotic figure was not definite. These findings were consistent with cytologic features of chondrosarcoma. Final diagnosis was confirmed as myxoid chondrosarcoma by mediastinoscopic biopsy and the tumor showed strong positivity for S-100 protein.
