We examined patients with suspected acute or intermittent biliary obstruction using hepatobiliary scintigraphy, ultrasonography and contrast cholangiography. Of 16 patients with confirmed common bile duct obstruction, sonography and scintigraphy disagreed in 8(50%). Scintigraphy revealed partial or complete common bile duct obstruction in 13 patients (81.3%) and 6 of them had no evidence of dilated biliary trees. It is concluded that disagreement between sonography and scintigraphy is not rare in patients with acute or intermittent biliary obstruction and hepatobiliary scintigraphy is useful in diagnosing obstruction prior to ductal dilatation.

전통적으로 슬관절 질병은 주로 방사선 촬영과 자기 공명 영상에 근거하여 진단과 치료를 하고 있다. 그러나 방사선 진단은 골 내부의 변화에는 좋은 영상을 가져다 주지만 연부 조직의 영상은 잘 볼 수 없는 단점이 있고 외래 진료실에서 실시간으로 할 수 없는 단점이 있다. 또 자기 공명 영상은 고가이고 역시 실시간으로 볼 수 없으며 정적인 정보만 제공한다. 초음파는 동적인 영상을 실시간으로 외래 진료실에서 즉시 볼 수 있고 비용이 저렴하며 동적 영상을 제공하고 연조직 영상을 잘 보여준다. 슬관절에서는 연조직 및 골 표면의 변화까지 관찰이 가능하므로 진단에 중요한 역할을 한다. 이 글에서는 정상적인 구조물의 초음파 영상과 병적 소견을 방사선 또는 자기 공명 영상 소견과 연계하여 소개하고 그 용도의 개략적인 것들을 설명하였다.

Background : The vasoreactivity of cerebral artery is currently the subject of increasing interest. Transcranial Doppler Sonography(TCD) is an accurate method of monitoring the blood flow velocities of the cerebral artery. We wished to assess the vasoreactivity between age-matched normal and cerebral infarction group. Method : We performed TCD findings in 40 normals and 20 cb-inf. subjects who arrived at hospital during 48 hours after attack. The former were devided into twenties normal group and fifties normal group. Result : 1. Fibrinogen levels showed significant changes between age-matched normal and cb-inf. group. 2. $V^{MEAN}$ of the both side Carotid Siphon during rest state increased significantly in cb-inf. group as compared with the age-matched normal group. 3. $V^{MEAN}and\;V^{MAX}$ of the both side carotid siphon during breath-hold state increased significantly in cb-inf. group as compared with the age-matched normal group. 4. Vasoreactivity of cerebral artery increased significantly in cb-inf. group as compared with the age-matched normal group. 5. $V^{MEAN}and\;V^{MAX}$ of the both side Radial artery during heat-stimuration state increased significantly in cb-inf. group as compared with the age-matched normal group. 6. Vasoreactivity of Radial artery increased significantly in cb-inf. group as compared with the age-matched normal group.

A 29-year-old Korean woman visited the Department of Surgery in MizMedi Hospital with a palpable itching mass on the right breast that had existed for the past 7 months. She had no history to eat either frogs or snakes, but had the history of drinking impure water. Sonography revealed a serpiginous hypoechoic tubular structure associated with partial fat necrosis in breast parenchymal layer and subcutaneous fat layer. It also revealed oval cystic lesions. At operation, an ivory white opaque ribbon-like worm that measured 16.5 cm in length and 0.5 cm in width was extracted. Anti-sparganum specific serum IgG level in the patient's serum (absorbance ＝ 0.71), measured by ELISA, was found to be significantly higher than those of normal controls (cut off point ＝ 0.21) . Sonography and ELISA appear to be helpful to diagnose sparganosis. Breast sparganosis is rarely found throughout the world.

This study reports the effectiveness of Korean medicine and Chuna manual therapy on patients with De Quervain's tenosynovitis. Two patients were treated with Chuna manual therapy, electro-acupuncture, moxibustion therapy. We used numeric rating scale (NRS), Finkelstein's test, sonography to measure changes during treatment. After each treatment, NRS, Finkelstein's test, sonography outcome were improved. Korean medicine including Chuna manual therapy can be effectively used to improve De Quervain's tenosynovitis. This study may suggest that korean medicine including Chuna manual therapy can be effective for De Quervain's tenosynovitis.

Bartter syndrome is an autosomal recessive hypokalemic salt-losing tubulopathy, and classic Bartter syndrome is associated with mutations in the CLCNKB gene. While chronic hypokalemia is known to induce renal cyst formation in different renal diseases, renal cyst formation in Bartter syndrome is rarely reported. Russian six-year-old identical male twins were referred to our hospital for the evaluation of renal cysts, which were incidentally detected on abdominal sonography due to diarrhea. Both twins had shown symptoms of polydipsia, polyuria, and nocturia since they were one year olds. Vital signs including blood pressure were normal in both twins. Renal sonography revealed nephromegaly, increased echogenicity of renal cortex, and various sized multiple cysts in both kidneys for both twins. Laboratory findings included hyponatremia, hypokalemia, hypochloremia, and metabolic alkalosis. Bartter syndrome with renal cysts were suspected. Genetic analysis for both twins confirmed a homozygous c.1614delC deletion on exon 15 of the CLCNKB gene, which was confirmed as a previously unreported variant to the best of our knowledge. They were managed with potassium chloride, nonsteroidal anti-inflammatory drugs, and angiotensin-converting-enzyme inhibitors. Metabolic alkalosis, hypokalemia, hypochloremia, and polyuria partially improved during the short course of treatment. This is the first report of a homozygous mutation in the CLCNKB gene in an identical twin, presenting with renal cysts.

Purpose: The aim of this study was to assess the agreement between intraoperative transcranial sonography (TCS) and postoperative computed tomography (CT) in patients with traumatic brain injuries. Methods: We performed a retrospective cross-sectional study of 35 patients who underwent TCS during surgery, among those who presented to a regional trauma center and underwent decompressive craniectomy between January 1, 2017 and April 30, 2020. Results: The mean difference between TCS and CT in measuring the midline shift was -1.33 mm (95% confidence interval, -2.00 to -0.65; intraclass correlation coefficient [ICC], 0.96; P<0.001). An excellent correlation was found between TCS and CT in assessing contralateral subdural hematomas (ICC, 0.96; P<0.001) and focal hematoma lesions (ICC, 0.99; P<0.001). A very good correlation between TCS and CT was found for measurements of ventricle width (ICC, 0.92; P<0.001). Conclusions: TCS during surgery is considered an effective diagnostic tool for the detection of intraoperative parenchymal changes in patients with traumatic brain injuries.

고주파 탐촉자를 이용한 초음파 검사는 음낭 검사의 일차선택 영상기법이다. 대부분의 고환 내 병변은 초음파 검사에서 저음영 병변으로 보인다. 고환 내 저음영 병변을 악성 혹은 양성 병변으로 구별하는 것은 중요한데, 병변의 악성 혹은 양성 여부에 따라 병변의 치료가 달라지기 때문이다. 이에 본 임상화보에서는 고환의 낭성 병변, 고환 종양, 고환의 염증성 병변, 고환 구역성 경색증, 그리고 고환 외상 등 다양한 고환 내 저음영 병변의 초음파 소견들에 대해 알아보고자 한다.

본 연구는 초음파검사를 이용하여 여성 골반내 질환의 발생빈도를 조사하였으며, 기초자료를 제공하기 위한 목적으로 수행되었다. S시에 있는 산부인과 병원에서 1년간에 골반강 초음파검사를 받은 25세 이상 69세 미만의 전체 여성 수검자 604명을 대상으로 하였다. 여성 골반내 질환은 자궁의 혹, 자궁내막 질환, 난소의 혹 및 경부낭종 등 4개 군으로 구분 조사하였고, 연구한 결과는 다음과 같이 나타났다. 위험요인으로 연령, 체중, 임신 횟수의 세 가지를 설정하였다. 분석 및 결론은 다음과 같다. 1) 연령별 발생빈도는 출산 연령층($25{\sim}35$세)에서 10.8%, 출산이 끝난 후 연령층부터 폐경 전 연령층($35{\sim}54$세)까지에서 38.9%, 폐경 후 연령층($55{\sim}69$세)에서 35.8%로, 출산이 끝난 후 연령층에서 폐경 전 연령층과 폐경 후 연령층에서 출산 연령층보다 발생빈도가 높게 나타났다. 2) 여성 골반내 질환의 발생빈도는 체중과 임신 횟수가 증가함에 따라서 증가하였다.
