기소연,김슬기,허태욱,백병현,김형석,윤웅 대한영상의학회 2016 Korean Journal of Radiology Vol.17 No.1

Chordoid glioma is a rare low grade tumor typically located in the third ventricle. Although a chordoid glioma can arise from ventricle with tumor cells having features of ependymal differentiation, intraventricular dissemination has not been reported. Here we report a case of a patient with third ventricular chordoid glioma and intraventricular dissemination in the lateral and fourth ventricles. We described the perfusion MR imaging features of our case different from a previous report.

기소연(So-yeon Kim),인태경(Tae-kyung In),김진우(Jin-woo Kim),김명수(Myung-su Kim) 한국신뢰성학회 2009 신뢰성응용연구 Vol.9 No.4

PSA (Pressure Sensitive Adhesive) is used for various purposes in electronic appliances such as double-sided tape for fitting parts, product’s name plate, and surface protecting film, and so forth. In several kinds of PSAs, this paper dealt with the failure analysis of PET (Polyethylene Terephthalate) acrylic adhesive tapes. The causes of interface failure were investigated through the test of adhesive strength, thickness, and structure. And test standard methods to prevent recurrences were established.

Cutaneous Scalp Metastases of Malignant Phyllodes Tumor of the Breast

이효재,임효순,기소연,이종은,이지신,박민호 한국유방암학회 2020 Journal of breast cancer Vol.23 No.3

Phyllodes tumor (PT) of the breast is a relatively rare fibroepithelial tumor that accounts for < 1% of primary breast neoplasms. PT is classified histologically as benign, borderline, or malignant, and a malignant PT has greater potential to metastasize than benign PT. Although almost all other organs can be affected, common metastatic sites are the lung and bone via the hematogenous route. There have been several studies reporting cutaneous and soft tissue metastases of PT, though the incidence is rare. Herein, we report a very rare case of scalp metastasis of malignant PT that was diagnosed via skin biopsy and surgical excision.

박혜미,임효순,기소연,이효재,이지신,박민호 대한영상의학회 2021 대한영상의학회지 Vol.82 No.4

Phyllodes tumors of the breast are relatively rare fibroepithelial tumors that account for less than 1% of primary breast neoplasms. Phyllodes tumors have epithelial and stromal components and they originate from the periductal stroma. They are classified as benign, borderline, or malignant. Carcinomatous differentiation of the epithelial components of phyllodes tumors is rare, and their imaging features have not been accurately described. Herein, we report a rare case of invasive ductal carcinoma originating from a borderline phyllodes tumor in a 21-yearold female with radiologic and pathologic findings. 유방 엽상종양은 전체 유방 종양의 1% 미만을 차지하는 드문 섬유상피종양이다. 엽상종양은유관주위 버팀질 세포에서 기원하여 상피 성분과 버팀질 성분을 모두 포함하는 특징을 가지며, 조직학적으로 양성, 경계성, 악성으로 구분된다. 엽상종양의 상피 성분에서 암이 발생하는 것은 매우 드물기 때문에 이에 대한 영상의학적 소견은 명확히 정립된 바가 없다. 이에 저자들은 21세 젊은 여성에서 경계성 엽상종양 내에서 생긴 침윤성 유관암을 경험하였기에 자기공명영상을 포함한 영상의학적 소견과 조직병리학적 소견을 보고하고자 한다.

김건수,김고은,김용균,기소연,배은희,김수완,김윤현 대한영상의학회 2018 대한영상의학회지 Vol.78 No.2

Purpose: To investigate risk factors of coronary arterial calcification in chronic kidney disease (CKD) patients who did not undergo hemodialysis or peritoneal dialysis. Materials and Methods: We enrolled 83 patients of normal renal function (Group I) and 112 patients of CKD [Group II (CKD stage 1–2) and Group III (CKD stage 3–5)], who were assessed coronary artery calcium score (CACS) with cardiac CT. CACS between the groups were compared. Risk factors for coronary artery calcification in patients with CKD including diabetes, hypertension, and smoking were identified as relevant to CACS using logistic regression analysis. Serologic data of electrolytes were analyzed to evaluate effect for coronary calcification in patients with CKD. Results: Group III showed significant increment of CACS compared to Group I at the CACS level over 400 [odds ratio (OR) = 7.581, p = 0.01]. The OR were decreased in non-diabetic patients group, increased in non-hypertensive patients group, no significant differences in non-current smoker group. Serum phosphorous level was the only factor which showed significant effect for increased CACS (OR of 2.649, p = 0.02). Conclusion: In CKD patients, higher stage of CKD was associated with increased CACS. Diabetes mellitus and increased serum phosphorous level would be considered as factors influencing coronary arterial calcification in CKD patients. 목적: 투석을 시행 받지 않은 만성 신질환(chronic kidney disease; 이하 CKD) 환자에서 관상동맥 석회화에 영향을 미치는 인자에 대하여 알아보았다. 대상과 방법: 투석을 시행 받지 않은 CKD 환자 중 심장 CT를 이용하여 관상동맥 칼슘 점수(coronary artery calcium score; 이하 CACS)를 측정한 112명과, 동일한 검사를 시행한 정상 신기능군 83명을 대상으로 하였다. 정상 신기능군을 Group I으로, CKD 환자들은 병기에 따라 Group II (1~2기 환자)와 Group III (3~5기 환자)로 나누고 이들 군 간의 CACS를 비교하였다. 또한 CKD 환자군에서 당뇨, 고혈압, 흡연 등이 CACS에 미치는 영향과, 이들의 혈액검사에서 CACS에 영향을 미치는 인자를 분석하였다. 결과: Group I에 비하여 Group III의 환자군에서 CACS 400 이상의 빈도가 유의하게 높았다[odd ratios (이하 OR) = 7.581, p = 0.01]. CKD 환자군에서 당뇨가 CACS의 증가에 유의한 결과를 보였으며, 혈청 인의 농도가 CACS 400 이상에서 유의한 관련성을 보였다(OR = 2.649, p = 0.02). 결론: CKD의 병기가 높을수록 CACS가 의의 있게 높았으며, 이들 환자에서 당뇨와 혈청 인의 농도가 관상동맥 석회화에 유의한 영향을 주었다.

Purpose: To investigate radiologic findings of intraosseous lipoma on plain radiograph and magnetic resonance imaging (MRI). Materials and Methods: Twenty-seven radiologically or pathologically confirmed intraosseous lipomas of long bones were included in the study. The size, involved bone and site, bone destruction pattern, border, internal calcification, bony expansion, cortical disruption and endosteal erosion were retrospectively analyzed on plain radiograph. The cases were classified into three stages based on calcification and cystic change. Eccentricity, margin, signal intensity of internal fatty portion, and presence of enhancement were analyzed. Results: Twelve tumors were located in femur and 8 in humerus. Proximal metaphysis was the most common involved site, with 14 cases. All tumors had geographic bone destruction, with sclerotic rim in 18 cases on plain radiograph. Internal calcification was seen in 18 cases and bony expansion in 6 cases. Twenty-three cases had cystic change in MRI. Eleven cases had eccentric location. The margins were well-defined in 11 cases. High signal intensity of fatty portion on fat-sat T2-weighted image was present in 17 cases. Contrast enhancement was seen in 17 cases. Conclusion: Knowledge of plain radiographic and MRI findings of intraosseous lipoma of long bones is valuable to the tumor diagnosis differentiation from other bone lesions. 목적: 장관골에 발생한 골내지방종의 단순촬영 소견과 자기공명영상(magnetic resonance image; 이하 MRI) 소견을 알아보고자 하였다. 대상과 방법: 장관골의 골내지방종으로 진단된 환자 중 단순촬영과 MRI를 시행한 27예를 대상으로 하였다. 단순촬영에서 크기, 위치, 골파괴 양상, 경계, 내부 석회화, 뼈확장, 피질골 단절 및 골내막 미란 등을 분석하였다. MRI에서는 석회화와 낭성변화에 따라 세 병기(stage)로 분류하였고, 병변의 경계, 편심성, 지방성분의 신호강도와 조영증강 유무를 평가하였다. 결과: 총 27예 중 대퇴골에서 12예, 상박골에서 8예가 발견되었고, 상부 골간단에서 발생한 경우가 14예로 가장 많았다. 단순촬영에서 모두 지도형 골파괴 양상을 보였으며, 경화성 테두리가 있는 경우가 18예로 가장 많았다. 내부 석회화는 18예에서, 뼈확장은 6예에서 관찰되었다. MRI에서 낭성변화가 있는 경우가 23예였고, 골수강 내에 편심성으로 위치하는 경우가 11예였다. 경계는 분명한 경우가 11예, 불분명한 경우가 16예였다. 병변의 지방성분이 높은 신호강도를 보인 경우가 17예였다. 조영제 주입 후 조영증강이 되는 경우는 17예였다. 결론: 장관골에 발생한 골내지방종의 단순촬영과 MRI 소견을 이해하는 것은 장관골에 발생한 골내지방종의 진단과 다른 골병변과의 감별에 도움이 된다.

Tumor Seeding after Percutaneous Transthoracic Needle Biopsy of Metastatic Pulmonary Ameloblastoma

박혜미,김윤현,임효순,기소연,이효재,이종은,정원기 대한영상의학회 2021 대한영상의학회지 Vol.82 No.4

Percutaneous transthoracic needle biopsy (PTNB) is a minimally-invasive procedure that is an indispensable tool for evaluating pulmonary lesions. Though extremely rare, tumor seeding of the pleura and chest wall can occur as a complication. Given that the breast is located anterior to the thorax, needle tracking through the breast is inevitable when PTNB is performed using the anterior approach. We describe tumor seeding of metastatic pulmonary ameloblastoma in the pectoralis muscle layer of the breast along the needle track of PTNB in a 51-year-old female presenting with a palpable lump in the right breast.

A Single-Center Experience of 2153 Tunneled-Cuffed Catheter Insertions Radiologically Placed via the Internal Jugular Vein: An Evaluation of Technical Success and Complication Rates Relative to Underlying Disease Conditions

박찬,임남열,김용태,노훈,기소연,김재규,김형욱,장남규 대한영상의학회 2015 대한영상의학회지 Vol.72 No.1

Purpose: To evaluate the technical success and complication rates of tunneled-cuffed catheter insertions radiologically placed via the internal jugular vein in patients with different types of underlying diseases. Materials and Methods: A total of 2153 tunneled-cuffed catheter insertions performed in 1926 patients between January 2008 and December 2012 were retrospectively reviewed. All procedures were conducted using sonography and fluoroscopy. The number of catheter maintenance days, technical success rates, and complication rates were analyzed based on radiologic and medical records. Results: A total of 204809 catheter maintenance days (mean, 95.35 days; range, 0–1710 days) were recorded. Technical success was achieved in 2148 insertions (99.77%). A total of 185 complications (8.61%, 0.903/1000 catheter days) were observed, including 22 procedure-related complications (1.02%). A total of 143 catheters (6.66%) were removed due to complications. Significant differences in complication rates were observed between patients with or without underlying hematologic diseases (11.65% vs. 7.02%, respectively; p = 0.000). Significant differences in catheter thrombosis were observed between patients in which right-sided or left-sided venous approaches were used (0.81% vs. 2.70%, respectively; p = 0.010). Conclusion: The very high technical success rates and very low procedure-related complication rates indicate insertion of a tunneled-cuffed catheter radiologically placed via the internal jugular vein is safe and effective.
