비장국소병변의 초음파 유도하 생검의 유효성과 안전성

한현영,김주헌,신경숙 대한초음파의학회 2002 ULTRASONOGRAPHY Vol.21 No.2

목적 : 비장 국소 병변에 대한 초음파 유도하 생검술의 임상적 유용성과 안전성에 대해 알아보고자 하였다. 대상 및 방법 : CT와 초음파 검사상 비장에 국소 종괴가 발견되어 초음파 유도하 생검을 시행한 11명의 환자를 (남자 9명, 여자 2명, 평균 연령: 49세) 대상으로 하였다. 여섯 명에서는 다 발성 종괴가 있었고, 이중 2명은 비장 종대가 동반되었다. 5명은 단일 종괴로 관찰되었고, 11명 모두 비장 외의 악성종양의 기왕력은 없었다. 18G 주사침을 사용하여 자동 총 생검을 시행하였고 병리조직검사에서 진단이 가능한 경우 성공이라 하였다. 결과 : 열 한 명의 환자 중 9명의 환자에서 조직학적인 진단이 가능하였고 (82%), 시술시의 경미한 통증외에 다른 합병증은 없었다. 비장 종대 없이 다발성 종괴가 있었던 5명은 호즈킨림 프종 (2명), 결핵 (1명), 경색 (1명), 혈관종 (1명)으로 확인되었다. 단일 종괴로 보였던 4명중에서 과오종이 2명, 림프관종, 만성농양이 각각 1명씩이었고, 과오종이 있던 한 명의 환자만이 비장절제술을 시행하였고 나머지 환자들은 내과적 치료를 하거나 더 이상의 처치가 필요치 않았다. 생검에서 병리조직검사에서 진단이 이루어지지 않은 비장종대와 다발성 종괴를 가지고 있던 2명의 환자는, 비장 절제술을 시행하여, 각각 호즈킨림프종과 비호즈킨림 프종으로 확인되었다. 결론 : 비장 국소 종괴의 초음파 유도하의 생검은 비장 질환의 정확한 진단을 얻을 수 있는 안전하고 유용한 시술방법이다. PURPOSE : To evaluate the diagnostic yield and safety of ultrasound (US)-guided percutaneous needle biopsy for the diagnosis of focal splenic lesions. MATERIALS and METHODS : US guided, automated needle biopsy using an 18-gauge cutting needle was performed in 11 patients, consisted of nine men and two women (mean age = 49 years), with focal splenic lesions detected on the CT or US. Six patients (55%) had multiple lesions while five (45%) had a single lesion. Two of eleven patients had splenomegaly. None of 11 patients had the prior diagnosis of extrasplenic or hematopoietic malignancies. The biopsy was considered successful if a specific pathological diagnosis was possible. The diagnostic yield and frequency of complication were retrospectively analysed RESULTS : Tissue adequate for histological diagnosis was obtained in nine (82%) of 11 patients, and no complications other than mild, localized discomfort occurred. Multifocal splenic lesions without splenomegaly in five patients were confirmed as Hodgkin’s disease (n=2), tuberculosis (n=1), infarction (n=1), and hemangioma (n=1). All single lesion in four patients were proven as benign conditions including hamartoma (n=2), lymphangioma (n=1) and chronic organizing abscess (n=1), and only one of them with a large hamartoma received splenectomy while others did not receive further treatment. Although in two (18%) patients with multiple lesions and splenomegaly, no specific diagnosis was established by US-guided biopsy, malignant lymphoma and Hodgkin’s disease were confirmed by surgery. CONCLUSION : US-guided automated needle biopsy is a safe and valuable procedure that can provides a specific diagnosis in patients with splenic lesions.

한현영,김종수,손명희,한영민,정경호,최기철 의과학연구소 1994 全北醫大論文集 Vol.18 No.1

Purpose : To ascertain the characteristic CT findings of multiple focal fatty infiltrations mimicking the metastases in the cirrhotic liver. Materials and method : Multiple hypodensities in the liver on abdominal CT scan proved to be fatty infiltraton by histological diagnosis(n=3) and showed changes on follow up CT scans(n=5) were retrospectively analysed in five patients with liver cirrhosis. Results : CT scans showed that all five patients had typical finding of liver cirrhosis and multiple hypodensities in the liver. These hypodensties were small, discrete, and diffusely distributed throughout the liver. There was enhancing central spot within some of the hypodensities. The hypodensities disappeared completely in two cases and partially disappeared in one case but there was no remakabel changes in the rest two cases on follow up CT scans. Conclusion : Fatty infiltration may be suggested if there if relatively uniform sized and discrete hypodensities with central enhancing dot in the cirrhotic liver. These hypodensities may be disappeared on follow-up CT scans.

부자(附子) 및 천오(川烏)를 포함한 처방이 혈중 Aspartate Aminotransferase, Alanine Aminotransferase 수치에 미치는 영향

한현영 ( Hyun Young Han ),황원덕 ( Won Duk Hwang ) 대한본초학회 2009 大韓本草學會誌 Vol.24 No.4

Objectives: Aconiti Lateralis Preparata Radix (附子) and Aconiti Tuber (川烏) are not commonly prescribed, but are necessary for some clinical conditions, despite of the fact that some negative effects have been known to occur with these medicines. This study shows the consequences for aspartate aminotransferase (AST), alanine aminotransferase (ALT) due to herbal medicines, including Aconiti Lateralis Preparata Radix (附子) and Aconiti Tuber (川烏). Methods: From 1st June 2007 to 10th May 2009, the results were analyzed for 64 patients belonging to the OO Oriental Medical Hospital who took herbal medicine, including Aconiti Lateralis Preparata Radix (附子) and Aconiti Tuber (川烏), more than 20 days. This is the study about the comparison and the investigation of AST, ALT. And the results were taken upon their hospitalization and to their departure. The Criteria of Diagnosis in Liver Injury of CIOMS was used as a standard for their examinations. Results: AST, ALT (total 64). The number of patients who were within normal reference value: 49. The number of patients who exceed the normal reference value after dosage, without satisfying the Criteria of Diagnosis in Liver Injury: 5. The number of patients who were recovered in normal reference value after dosage: 9. The number of patients who satisfying the Criteria of Diagnosis in Liver Injury after dosage: 1. Conclusions: This results suggest that these herbal medicines, including Aconiti Lateralis Preparata Radix (附子) and Aconiti Tuber (川烏), didn`t cause adverse side-effects on AST, ALT of the patients who are taking them.

이경훈,한현영,김희진,김희경,이문수 대한초음파의학회 2015 ULTRASONOGRAPHY Vol.34 No.3

Purpose: To evaluate ultrasonographic accuracy in the differentiation of a bezoar from feces in a small bowel obstruction showing feces-like material just proximal to the transitional zone in abdominal computed tomography (CT). Methods: This study included 14 patients who showed feces-like material just proximal to the transitional zone, among 302 patients diagnosed with small bowel obstruction on abdominal CT. The diagnostic signs of a bezoar on ultrasonography included an arc-like surfaced intraluminal mass, posterior acoustic shadow and twinkling artifacts. The diagnostic performance of ultrasonography in each patient was compared with a final diagnosis that was surgically or clinically made. Results: Among the 14 patients, seven were ultrasonographically diagnosed as having a bezoar, and five of the seven were surgically diagnosed as having a phytobezoar. The remaining two of the seven showed complete symptomatic improvement before surgery. The other seven patients were ultrasonographically diagnosed as not having a bezoar. Among them, six patients were conservatively treated with symptomatic improvement, suggesting the absence of a bezoar. The remaining one patient was confirmed not to have a bezoar during adhesiolysis. In all patients, the ultrasonographic diagnosis agreed with the clinically confirmed diagnosis. Conclusion: Ultrasonography might be an accurate method for the differential diagnosis of feceslike material just proximal to the transitional zone in abdominal CT. It can help radiologists to quickly and easily diagnose a bezoar

Giant cavernous hemangioma coexistent with diffuse hepatic hemangiomatosis presenting as portal vein thrombosis and hepatic lobar atrophy

유보름,한현영,최소영,김주헌 대한초음파의학회 2014 ULTRASONOGRAPHY Vol.33 No.1

A combination of giant hepatic hemangioma and diffuse hemangiomatosis is extremely rare in adults. Even when they are large, hemangiomas are soft and rarely compress adjacent structures. A 78-year-old man presented with abdominal pain and distension. Ultrasonography, computed tomography, and magnetic resonance imaging demonstrated a large expansile mass replacing the medial segment and caudate lobe with diffusely scattered nodules in the entire liver. The large hilar mass contained a central nonenhancing area and had a mass effect, leading to left portal vein occlusion. The image findings also revealed two unprecedented findings: left lateral segmental atrophy of the liver and recent portomesenteric vein thrombosis. The hepatic lesions were confirmed with hemangiomas by ultrasonography-guided biopsy. We diagnosed intrahepatic portal vein obstruction caused by a mass effect of giant hepatic hemangioma coexistent with diffuse hemangiomatosis, resulting in hepatic segmental atrophy and extrahepatic portal vein thrombosis.

Xanthogranulomatous cholecystitis is an uncommon benign inflammatory disease of the gallbladder characterized histopathologically by extensive lipid-containing histiocytes. It has been usually mistaken for gallbladder cancer due to diffuse wall thickening of gallbladder with peripheral infiltration radiographically. Xanthogranulomatous cholecystitis has been reported to combine cholelithiasis frequently. A 59-year-old man was admitted with jaundice and right upper quadrant pain. By abdominal ultrasonogram, computed tomography scan, cholangiogram, and repeated biopsy, his case was diagnosed as xanthogranulomatous cholecystitis associated with Mirizzi syndrome. An exploratory laparatomy was performed. On operation, the gallbladder wall was irregularly markedly thickened and multiple stones existed in the gallbladder. The largest one (2×1.5×1.5 cm) of these stones was impacted in necrotic defect site between gallbladder wall and common hepatic duct wall, and it partially obstructed (80%) the common hepatic duc Partial cholecystectomy with T-tube drainage was performed. Postoperatively, we diagnosed this case as xanthogranulomatous cholecystitis associated with Mirizzi syndrome.

Retrograde Colonic Stent Implantation Assisted by Percutaneous Colostomy: A Case Report

임형근,한현영,전동진 대한영상의학회 2009 대한영상의학회지 Vol.61 No.4

We present a patient with disseminated pancreatic cancer who presented with symptoms of acute obstruction of the sigmoid colon. It was not possible to pass the region of the obstruction with a guide wire under colonoscopy and fluoroscopy. Consequently retrograde implantation of stents was performed successfully with the assistance of a minimally-sized colostomy when compared with a previously described procedure in the literature.
