갑상선 조직 전체가 설기저부에 발생한 이소성 설갑상선 증례를 경험하였기에 그 방사선학적 소견을 문헌고찰과 함께 보고하고자 한다. 증례는 59세 여자 환자로 40 일전부터 발생한 음성 변화를 주소로 내원하였다. 이학적 검사에서 설 기지부 중앙에 회백색의 격막에 둘러 쌓인 3 cm 가량의 종괴가 있었으며, 종괴는 내장으로 돌출하여 구인두를 막고 있었다. 경부 전산화 단층촬영 측면 정찰 촬영에서, 설 기저부에 후방으로 돌출하여 구인두를 막고 있는 경계가 분명한 연부조직 종괴가 보였으며, 전산화 단층촬영 동맥기와 정맥기에 주변의 혈관과 비슷한 강하고 균일한 조영증강을 보이는 장경 2.5 cm의 원형 종괴가 있었다. 또한 갑상선이 있어야 할 경부 전방 공간에서 정상 갑상선 조직은 전혀 보이지 않았다. 설 기저부의 종괴에서 생검을 시행하였으며 병리 검사에서 갑상선 조직으로 진단되어 설갑상선으로 확진되었다. The authors report a case of ectopic thyroid that whole thyroid tissue was replaced by lingual thyroid. A 59-year-old female presented with dysphonia duration of 40 days. On physical examination, there was a 3 cm sized well encapsulated whitish mass protruding to oral cavity in milline of tongue to base. Computerized tomography of neck revealed homogeneously enhancing well marginated 2.5 cm sized round mass in the cecum of tongue base on arterial and venous phase. And there was no normal thyroid gland in lower anterior neck.

한기석 대한영상의학회 1995 대한영상의학회지 Vol.32 No.4

Purpose : Authors investigated the associated findings and their value in the diagnosis of anterior cruciateligament(ACL) injury in MR image. Material and Methods : The knee MR images of 47 patients with ACLinjury(complete;24, partial;23) and 61 patients with normal ACL confirmed by the knee arthroscopy or operationwere reviewed retrospectively. The degree of anterior translocation of tibia and the degree of posterior cruciateligament(PCL) buckling were evaluated. The prevalence and pattern of associated adjacent bone, ligament andmeniscus injuries were studied. Results : The means($\pm$2standard errors) of anterior translocation were differentsignificantly in statistical analysis(p <0.001, student t-test) between injury group(7.51$\pm$1.16mm) and normalgroup(-0.56$\pm$0.92mm) . In the level of 5mm of anterior translocation for the criteria of ACL injury, thesensitivity, specificity, accuracy were 78.7%, 89.5%, 84.3% for each. The means of PCL buckling ratio were alsodifferent statistically between injury group(0.23$\pm$0.02) and normal group(0.17$\pm$0.01)(p<0.001). In the level of0.20 for diagnostic criteria of ACL injury, the sensitivity, specificity, accuracy were 71.4%, 83.6%, 78.4% foreach. Thirty one medial meniscus tear(66%), thirteen lateral meniscus tear(28%), ten medial collateral ligamentinjury(28%), one PCL injury(2%) were associated with ACL injury. The twenty nine bone marrow changes were found intwenty patients(43%) which including acutely injured seven patients. In acute cases, the bone marrow changes weredepicted as diffuse or focal high signal intensity lesions in lateral femoral or tibial condyles in contrast tothe changes in chronic cases were depicted as focal low signal intensity lesions in variable location. Lateralfemoral condylar notch depression were found in nine patients(19%) and avulsion fractures of anterior tibial spinein four patients(9%). Conclusion : The associated findings with ACL injury (anterior translocation, buckling ofPCL, associated bone, ligament and meniscus injuries) are considered to be helpful in the diagnosis of ACL injuryon Knee MR images, when the findings of anterior cruciate ligament itself are not confirmative.

신경증을 수반한 Paroxysmal Dystonic Seizure 2례

한기석,정영조 인제대학교 1989 仁濟醫學 Vol.10 No.3

신경증을 수반한 paroxysmal dystonic seizure 2례를 치험하였기에 문헌 고찰과 함께 이를 보고한다. The auther experienced a varient form of idiopathic reflex epilepsy ; paroxysmal dystonic seizure. The Two cases described in which motor seizure, consisting usually of focal or generalized paroxysmal dystonic writhing movements without loss of consciousness, were provoked by sudden movement. And they also suffered from panic disorder with agoraphobia, conversion disorder, avoident behavior and hypochondriacal ideation due to underlying paroxysmal dystonic seizure. This form of epileptic attack showed good response to anticonvulsant medication and the neurotic symptoms were relieved by supportive psychotherapy and behavioral therapy.

부인두 종괴 : CT 및 MR 소견

한기석 대한영상의학회 1994 대한영상의학회지 Vol.30 No.3

Purpose : Authors reviewed CT and MR findings of patients with parapharyngeal masses, and their incidence and characteristic findings were studied.Materials and Methods: We reviewed 27 CT and 9 MR of pathologically proven 29 patients with primary parapharyngeal mass Neurogenic tumor (17 cases) and other rare masses (3 carotid body tumors, 2 pleomorphic adenomas, 2 cavernous hemangiomas, 1 cavernous Iymphangioma, 2 carotid artery pseudoaneurysrns, 1 non-Hodgkin's Iymphoma, 1 idiopathic cervical fibrosis) were included and the characteristic CT and MR findings were studied.Results: Neurilemmoma was seen as a well-demarcated, solid mass of heterogeneous attenuation or intensity, so that pleomorphic adenoma of minor salivary gland origin could not be differentiated by demarcation, attenuation, or signal intensity of the tumor itself. The direction of carotid artery displacement was not constant in cases of neurilemmomas while the styloid process was constantly displaced laterally in all cases. Characteristic CT and MR findings of other rare tumors were described.Conclusion : Neurogenic tumor is the most common parapharyngeal space mass and the direction of displacement of styloid process might be helpful in differential diagnosis from pleomorphic adenoma. Other rare tumors showed very characteristic CT and MR finidings and could be differentiated easily.

방추형 동맥류 모형에서 자기공명 혈관조영술의 신호강도에 대한 연구

한기석 대한자기공명의과학회 1998 Investigative Magnetic Resonance Imaging Vol.2 No.1

Purpose : Authors correlated the three-dimensional time-of-flight MRA signal intensity characteristics and flow profile simulated by computer in an experimental flow phantom model. Materials and Methods : The three-dimensional time-of-flight MRA was performed in a fusiform flow phantom and analyzed the flow signal. computer assisted flow simulation was performed in same flow geometry. The MRA signal intensity and flow velocity distribution and direction was compared. Results : The flow was depicted as homogeneous signal internsity in inlet and outlet area and inhomogeneous signal intensity in fusiform area. Typically, the flow was depicted as target appearance in transition area to outlet. Whereas mean signal internsity decreased slowly in fusiform area, it rapidly dropped and resumed in transition area to outlet. In computer assisted flow simulation, Whereas there were flow velocity decrease and flow direction change to peripheral in entrance to fusiform area, ther were rapid flow velocity resuming and flow direction change to central in transition area to outlet. Conclusion : The signal loss and target appearance in transition area to outlet is characteristic of fusiform flow. These signal changes correlate with abrupt flow velocity and direction change well.

청소년 자살의 원인과 치료적 개입

한기석,정영조 인제대학교 1992 仁濟醫學 Vol.13 No.2

최근 청소년 자살이 증가하고 있으므로 청소년 자살의 원인과 자살의 예측인자에 대한 고찰을 통하여 이들의 자살을 예방하고 치료에 도움이 되고자 하였는데 특히 부모, 교사 및 일반 타과 의사에게 도움이 되도록 기술하였다. Currently, the suicidal rate is rising most rapidly in adolescence. In this article, we review the recent research for causes and therapeutic intervention of adolescent suicide. The risk factors include psychiatric disorders-such as affective, conduct, and subatance abuse disorders-, developmental and personality types, familial and environmental factors, and biologic factors. It is important for us to prevent suicide that is extensive efforts for early identification and intervention. And it is also needed changes in value system, the attitude of repoters, and the way of bringing up children for prevention it,
