종격동에 발생한 혈관종은 전체 종격동 종양의 0.5% 미만을 차지할 정도로 드문 질환이다. 후종격동에 발생한 혈관종의 경우는 전종격동에 비해 더 드문 것으로 알려져 있다. 환자는 21세 여자로 단순흉부 방사선촬영상 후종격동에 비정상적인 음영을 보여 본원으로 전원되어 시행한 흉부 전산화 단층촬영과 흉추 자기공명 영상촬영에서 척수 경막까지 도달되어 있는 아령모양의 후종격동 종양 소견을 보였다. 이에 수술적 절제를 시행하였고 병리 조직학적 검사결과 3${\times}$4${\times}$2 cm의 모세혈관상 혈관종의 소견이 관찰되었다.

Background and Purpose : The aim of the present study was to investigate the prodromes of stroke in already attacked patients and to prove the traditional hypothesis that some symptoms were to be prodromes of stroke in the oriental medicine. Methods : The questionnaire which was based on symptoms of traditional hypothesis was distributed to subacute stroke patients who were confirmed by Brain CT or MRI in Oriental Medical Hospital, Kyung Hee University, except patients with indistinct onset, symptoms proved any other disease. Results : Eighty-three patients(82.2%) felt some prodromal symptoms and fifty-nine patients (58.4%) underwent a change in their life within one week before onset. Most common prodromal symptoms was the weakness or numbness of limbs, single or unilateral. Conclusion : Our results suggest that the prodromal symptoms before stroke can be regarded as predicting sign. And we think that these research may contribute to preventing stroke and relapse.

Objective : Neuroimaging data are of paramount importance in making correct diagnosis. We herein evaluate the clinical usefulness of image transfer using cellular phones to facilitate neurological diagnosis and decision-making. Methods : Selected images from CT, MRI scans, and plain films obtained from 50 neurosurgical patients were transferred by cellular phones. A cellular phone with a built-in 1,300,000-pixel digital camera was used to capture and send the images. A cellular phone with a 262,000 color thin-film transistor liquid crystal display was used to receive the images. Communication between both cellular phones was operated by the same wireless protocol and the same wireless internet service. We compared the concordance of diagnoses and treatment plans between a house staff who could review full-scale original films and a consultant who could only review transferred images. These finding were later analyzed by a third observer. Results : The mean time of complete transfer was $2{\sim}3\;minutes$. The quality of all images received was good enough to make precise diagnosis and to select treatment options. Transferred images were helpful in making correct diagnosis and decision making in 49/50 [98%] cases. Discordant result was caused in one patient by improper selection of images by the house staff. Conclusion : The cellular phone system was useful for image transfer and delivery patient's information, leading to earlier diagnosis and initiation of treatment. This usefulness was due to sufficient resolution of the built-in camera and the TFT-LCD, the user-friendly features of the devices, and their low cost.

Objective: The purpose of this study is to report the case of a patient with non-small cell lung cancer (NSCLC) with Programmed cell death protein 1 (PD-1) mutation treated by Integrative Medicine Therapy (IMT). Methods: A patient with metastatic NSCLC received pembrolizumab 200mg intravenously for every 3 weeks from July 2017. Repeat cycle every 3 weeks since July 2017. The patient has been treated with Integrative Medicine Therapy (IMT) since December 2016. The tumor size was measured by computed tomography (CT) and magnetic resonance imaging(MRI). Adverse events were evaluated by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 5.0. Results: After combined treatment, the extent of proximal portion of primary tumor in the left lower lobe was decreased and disease status was stable radiologically. No evidence of newly developed metastatic lesions in the brain since May 2017. The patient did not experience any adverse event according to NCI-CTCAE ver. 5.0. Conclusion: This case study suggests that Integrative Medicine Therapy (IMT) may contribute to tumor response, in conjunction with Pembrolizumab on the treatment of patients with NSCLC.

Purpose: Concomitant ankle injuries associated with tibial shaft fractures can affect postoperative ankle joint pain and various postoperative ankle complications. This study compared the clinical outcomes between surgical treatment and conservative treatment of concomitant ankle injuries associated with tibial shaft fractures. Materials and Methods: From January 2015 to June 2020, a retrospective study was conducted on 118 tibia shaft fractures at the orthopedics department of the hospital. Associated ankle injuries were analyzed using plain radiographs, computed tomography (CT), magnetic resonance imaging (MRI), and intraoperative stress exams. The clinical outcomes were compared using the pain visual analog scale (pain VAS), American Orthopaedic Foot and Ankle Society Ankle-Hindfoot score (AOFAS score), and Karlsson-Peterson ankle score (KP score). Results: Seventy-two (61.02%) of the 118 cases were diagnosed with associated ankle injuries. Fifty-six cases underwent surgery for the ankle injury, and 16 cases underwent conservative treatment. The clinical results (according to the pain VAS score, AOFAS score, the KP score) were 1.79±1.26, 94.48±4.03, and 94.57±3.60, respectively, in the surgical treatment group, and 3.00±1.03, 91.06±3.02, and 91.25±3.31, respectively, in the conservative treatment group. Conclusion: Surgical treatment showed better clinical outcomes than conservative treatment in concomitant ankle injury in tibia fractures. Therefore, surgical treatment produces better clinical outcomes than conservative treatment in concomitant ankle injuries in tibia fractures. Hence to improve the clinical outcomes, more attention is needed on ankle joint injury in tibial shaft fractures for selecting suitable surgical treatments for those patients.

담도선섬유종은 매우 드문 담도상피성 종양으로서 양성 종양으로 분류된다. 그럼에도 불구하고, 담도선섬유종으로부터 악성 종양이 발생했다는 몇 개의 증례가 보고되어 왔다. 하지만 담도선섬유종과 그로부터 발생한 악성 신생물에 대한 영상의학적 소견은 잘 알려져 있지 않다. 우리는 담도선섬유종에서 발생한 담관암의 증례를 초음파, 컴퓨터단층촬영, 자기공명영상 사진과 함께 설명하고, 이와 감별할 질환들의 영상의학적 소견을 고찰하고자 한다.

간세포암종은 역동적 조영증강 컴퓨터단층촬영이나 자기공명영상에서의 동맥기 조영증강 및 문맥기 또는 지연기 씻김현상과 같은 전형적 영상 소견을 기반으로 비침습적으로 진단할 수 있다. 그러나 일부 간세포암종은 비전형적인 영상 소견을 나타내기 때문에 영상의학과 의사는 진단에 있어 어려움에 직면하게 된다. 더욱이 동맥 문맥 단락, 혼합 간세포-담관암, 간내 담관암, 혈관종과 같이 많은 간세포암 유사 병변들이 다수 존재하여 영상을 통한 감별 진단에 난항을 겪는다. 초기 영상 검사에서 간세포암종과 이러한 유사 종양을 구별하는 능력은 적절한 관리 및 치료 결정에 중요하다. 따라서 본 임상화보에서는 간세포암종의 비전형적 영상 소견과 간세포암종을 모방하는 악성 및 양성 병변들의 영상 소견을 제시하고 감별 진단을 좁히는 데 도움이 될 수 있는 중요한 단서들에 대해 알아보고자 한다.

척수 경막외 동정맥루는 매우 드문 질환으로 진단과 치료가 어렵다. 무증상 환자도 있으나 동정맥단락으로 척수주위정맥으로 역류되고 늘어난 정맥이 인접한 신경근을 압박하면서 증상이 생길 수 있다. 본 증례는 31세 남자 환자로 2년 동안 지속되는 요통, 방사성 허벅지통증, 하지 감각변화로 내원하였다. 컴퓨터단층촬영, 자가공명장치 및 척수혈관조영술에서 요추의 경막외 공간에서 동정맥단락에 의해 늘어난 정맥이 신경근을 압박하고 있는 척수 경막외 동정맥루로 진단하였다. 코일색전술을 시행하여 동정맥단락을 차단하였고 수일 내에 신경근 압박증상이 호전되었다. 이번 증례에서는 척수 경막외 동정맥루에서 외과적 수술의 대안으로 코일 색전술이 효과적인 치료가 될 수 있다는 것을 보여주었다.

Objective: To summarize the high-resolution computed tomography (HRCT) and magnetic resonance imaging (HRMRI) features of duplicated internal auditory canals (DIACs). Materials and Methods: Ear HRCT data of 64813 patients with sensorineural hearing loss (SNHL), obtained between August 2009 and November 2017, were reviewed. Among these patients, 12 (13 ears) were found to have DIACs, 9 of whom underwent HRMRI. Their images were evaluated by two otoradiologists. Results: The rate of occurrence of DIAC among SNHL patients was 0.019% (12/64813). The internal auditory canals of 13 ears were divided into double canals by complete (n = 6) and incomplete (n = 7) bony septa, with varied orientations ranging from horizontal to approximately vertical. All of the anterosuperior canals extended into the facial nerve (FN) canal, except for 1, which also extended to the vestibule. The posteroinferior canals ended in the cochlea and vestibule, except for 2, which also connected to the FN canals. Magnetic resonance images revealed that 77.8% (7/9) and 22.2% (2/9) of vestibulocochlear nerves (VCNs) were aplastic and hypoplastic, respectively. Furthermore, 88.9% (8/9) of FNs were normal, except for 1, which was hypoplastic. All of the affected ears also had other ear anomalies: a narrow, bony cochlear nerve canal was the most common other anomaly, accounting for 92.3% (12/13). Malformations of other systems were not found. Conclusion: Double-canal appearance is a characteristic finding of DIAC on HRCT, and it is usually accompanied by other ear anomalies. The VCN usually appears aplastic, with a normal FN, on HRMRI.
