경화성 복막염 (sclerosing peritonitis)은 복막 투석 (continuous ambulatory peritoneal dial-ysis,CAPD)을 하고 있는 환자들에서 드물게 발생하는 합병증으로 소장의 기능장애, 복부 통증,투석 기능의 저하를 가져오며 심한 경우에는 장폐색을 일으킬 수 있다.경화성 복막염에서 드물게 석회화를 동반할 수 있으며 작은 석회화로 시작하여 광범위한 석회화로 진행될 수 있다. 저자들은 복부 단순 촬영과 컴퓨터 단층촬영 (CT)에서 광범위한 석회화를 동반한 경화성복막염의 전형적인 소견을 보인 예를 보고하고자 한다. Sclerosing peritonitis is an uncommon complication of continuous ambulatory peritoneal dialysis (CAPD) and can lead to small bowel dysfunction involving abdominal pain, progressive loss of ultrafiltration, and small intestinal obstruction. Peritoneal thickening, in which calcification can develop, often starts as a small plaque which gradually becomes larger. We report a case of CAPD-related calcifying peritonitis.

목적 :갑상선에서 직경 10 mm 미만의 소결절의 초음파 소견을 분석하여 양성과 악성결절의 감대 상 및 방 법 : 58명의 환자에서 수술 및 세침흡인검사에 의해 병리조직학적으로 확진된 최대직경 10 mm 미만의 갑상선 소결절 72예(양성 44예, 악성 28예)의 초음파 소견을 후향적으로 분석하였다. 양성과 악성결절에서 병변의 경계, 내부에코의 양상 및 미세석회화, 결절내부 낭성변화, 결절주위 저에코의 테두리 존재여부를 비교하였다. 결과 : 초음파소견에서 악성결절은 불분명한 경계면을 보이는 경우가 많았다(61% vs 11%, p < 0.05). 내부에코 양상에서는 양성결절은 등에코나 고에코를 보이는 경우가 많았으며(45% vs 18%, p < 0.05) 악성결절은 현저한 저에코를 보이는 경우가 많았다(39% vs 18%, p < 0.05). 미세석회화는 악성결절에서 더 많이 관찰되었고(36% vs 9%, p < 0.05) 결절내 부의 낭성변화(39% vs 7%, p < 0.05) 및 결절주위 저에코의 테두리(41% vs 18%, p < 0.05)는 양성결절에서 더 많이 관찰되었다. 결론 : 초음파는 갑상선 소결절에서 양성과 악성결절의 감별에 도움이 될 것으로 사료된다. PURPOSE : To evaluate the usefulness of ultrasonography in the differentiation between benignity and malignancy in the evaluation of small thyroid nodules (the longest diameter < 10 mm). MATERIALS and METHODS : Fine needle aspiration or surgery was performed for the evaluation of seventy two (44 benign and 28 malignant) small thyroid nodules from fifty eight patients. Ultrasonographic findings were retrospectively reviewed for the margin, echogenecity, presence of microcalcification, intranodular cystic change and peripheral hypoechoic halo. RESULTS : Ill-defined margin was more common in malignant nodules (61% vs 11%, p<0.05). In internal echogenecity, either iso- or hyperechogenicity was more coomon in benign nodules (45% vs 18%, p<0.05) while malignant nodules were often markedly hypoechoic (39% vs 18%, p<0.05). Malignant nodules contained more microcalcifications (36% vs 9%, p<0.05) whereas benign nodules often showed intranodular cystic change(39% vs 7%, p<0.05) and hypoechoic halo (41% vs 18%, p<0.05). CONCLUSION : Ultrasonography can be useful in the differentiation between benign and malignant small thyroid nodules.

ObjectivesThe present study was designed to investigate the effects of bee venom extract pharmacopunctureon (BVP) at 肩井 (GB21) on the changes in regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) in normal rats, and further to determine the mechanisms. MethodsWe purchased rats about 300g and prepared diluted BVP with normal saline. And we injected diluted BVP to rats gradually progressed from 0.001 mg/kg to 0.1 mg/kg at corresponding region to GB21. After injection, we measured the changes in rCBF and MABP of rats. In addition, to determine the mechanisms of this changes, we did the same experiments twice more after pretreatment with indomethacin and metylene blue separately. ResultsBVP significantly increased rCBF but decreased MABP, suggesting that BVP potently may increase rCBF by dilating pial arterial diameter. Furthermore, the increase of BVP-induced rCBF and the decrease of BVP-induced MABP were significantly blocked by pretreatment with cyclooxygenase inhibitor, indomethacin (1 mg/kg, i.p.). But the increase of BVP-induced rCBF and the decrease of BVP-induced MABP were not blocked by pretreatment with guanylate cyclase inhibitor, methylene blue (0.01 mg/kg, i.p.). ConclusionsThese findings indicate that the action of BVP is mediated by cyclooxygenase. Furthermore these results suggest that BVP can increase rCBF in normal state, as well as improve the stability of rCBF in ischemic state. (J Korean Med Rehab 2013;23(3):37-44)

The purpose of this study is to report the effect of Korean medical treatment in patient with herpes zoster opthalmicus. The patient was treated by acupuncture, herbal medicine, Hwangryunheadok-tang(HuanglianFiedu-Tang) and Ginseng pharmacopuncture, and western medicine from July 25th to August 8th 2012. We measured visual analogue scale(VAS) and observed the change of herpes size through the picture using digital camera. Before this treatment, he took western medicine for 8 days from onset but there was no effect. However, when this Korean medical treatment was finished, VAS score changed from 10 to 1. Korean medical treatment was effective in herpes zoster. But in treating herpes zoster antiviral agents of western medicine might be needed in early stage. And further studies are needed to figure out the effects of Korean medical treatment on herpes zoster.
Retroperitoneal Bronchogenic Cyst Located in the Presacral Space: A Case Report
김아연,민선정,김현철,최정아 대한영상의학회 2021 대한영상의학회지 Vol.82 No.1
Bronchogenic cysts are rare congenital anomalies that are most frequently found in the mediastinum along the tracheobronchial tree, especially in the posterior aspect of the superior mediastinum. Bronchogenic cysts have also been reported in intrapulmonary, intrapericardial, abdominal, and retroperitoneal locations. Herein, we report a case of a retroperitoneal bronchogenic cyst in the presacral space. The patient was diagnosed based on a post-operative histopathological examination.
Pancreatic Schwannoma with Cystic Degeneration: A Case Report and Literature Review
박준석,민선정,김현철,최정아 대한영상의학회 2021 대한영상의학회지 Vol.82 No.1
Schwannomas originate from Schwann cells, and they are the most common benign neoplasms of the peripheral nerves. They can occur in most parts of the body but have a predilection for the head, the neck, and the flexor aspects of the extremities. Pancreatic schwannomas are uncommon, and only a few cases have been reported in the English literature. Approximately two-thirds of pancreatic schwannomas undergo cystic degeneration, and they should be considered in the differential diagnosis of solid pancreatic tumors with cystic changes to facilitate accurate diagnosis and optimal treatment. We report a case of a pathologically proven schwannoma in the pancreatic tail with multiple cystic and hemorrhagic changes followed by a review of relevant literature.
Intrahepatic Splenosis Mimicking Hepatocellular Carcinoma: A Case Report
황은진,민선정,김영철,최정아 대한영상의학회 2019 대한영상의학회지 Vol.80 No.2
Splenosis refers to autotransplantation of splenic tissue into intraabdominal, intrathoracic or even any other parts of body and occurs after splenic trauma or splenectomy. Hepatic splenosis is usually incidental found during imaging workup. It can mimic other hypervascular mass because it presents vivid and heterogeneous enhancement representing that of splenic tissue. So far, about 20 cases of intrahepatic splenosis have been described in the literature. Herein we report a case of intrahepatic splenosis mimicking hepatocellular carcinoma in a patient with liver cirrhosis. The patient was finally diagnosed on the basis of specific radionuclide imaging.
