류지화 대한영상의학회 1997 대한영상의학회지 Vol.37 No.4

Purpose : The purpose of this study is to assess the utility of PTBD spiral CT cholangiography, after infunsion of contrst media through a PTBD tube, for evaluatioin of a biliary lesion after emergency PTBD due to severe jaundice.Materials and Methods : Forty patients with emergency PTBD due to extrahepatic biliary obstruction were transferred to our clinic and prospectively studied. The causes of obstruction were 17 extrahepatic cholangiocarcinomas(including three Klatskin's tumors), seven pancreatic head carcinomas, six calculous diseases of the common bile duct, six periampullary lesion, two ampulla of Vater carcinomas, one gall bladder carcinoma with invasion of the common hepatic duct, and one cholangitis. diagnosis was on the basis of pathologic, radiologic, and clinical findings. Pre-contrast CT scaning was performed. After the infusion of contrast media(iothalamate : normal saline=1 : 10) through a PTBD tube, spiral CT scans were obtained. After IV infusion of contrast media(Ultravist, 100cc), early-and delayed- phase spiral CT scans were obtainet 45 and 210 seconds, respectively, with an interscan interval of 5mm. 3-D CT cholangiograms were then recondtituted. Spiral CT without infusion of contrast media through a PTBD tube and PTBD spiral CT cholangiography were performed in 14 cases. The level of extrahepatic biliary obstruction was categorized as either upper, middle, or lower third. In 21 surgically confirmed cases, we evaluated the accuracy with which the level and cause of obstruction was determined ; levels and causes during surgery and by as seen on PTBD cholaniography were compared.Results : The levels of obstruction diagnosed on PTBD spiral CT cholangiography and on 3-D CT cholangiography corresponded in all cases to the levels during surgery and on PTBD cholangiography [upper third (n=7), middle third (n=12), lower third (n=21)], and the level diagnosed on spiral CT without infusion of contrast media through a PTBD tube corresponded to the level during surgery in ten of 14 cases. The cause of obstruction diagnosed on PTB spiral CT cholangiography corresponded to pathologic findings in 19 of 21 cases. In 15 cases, 3-D CT cholangiography was diagnostically helpful.Conclusion : PTBD spiral CT cholangiography is useful diagnostic method for determining the level and cause of biliary obstructoin.

중이에 생긴 골종: 증례 보고

류지화 대한영상의학회 2005 대한영상의학회지 Vol.52 No.3

중이에 생긴 골종은 극히 드문 양성 종양으로써 지금까지 전세계적으로 21예만이 보고되었다. 주로 갑각, 추체돌기, 이소골 등에서 생기며, 증상이 없거나 전도성 청력손실을 유발할 수 있다. 저자들은 만성 중이염이 있는 38세 여자에서 중이에 생긴 골종 1예를 경험하였기에 CT와 병리 조직 소견을 보고하고자 한다. Osteomas of the middle ear are exceedingly rare benign neoplasms. To date, only 21 cases have been reported in the literature. They arise from the promontory, the pyramidal process and the ossicles, and they are usually asymptomatic or cause some conductive hearing loss. We report here the CT & pathologic findings in a 38-year-old woman with a benign osteoma of the middle ear along with chronic otitis media.

Spontaneous Retropharyngeal Hematoma: A Case Report and Literature Overview

류지화 대한영상의학회 2014 대한영상의학회지 Vol.70 No.2

A spontaneous retropharyngeal hematoma is a rare condition with a difficult diagnostic. This disease may rapidly progress to an airway obstruction. The author reports about a case of a 56-year-old man with an acute onset of sore throat, dysphonia and dyspnea. A retropharyngeal high attenuated soft tissue density could be seen on the neck CT. A rapid improvement of the retropharyngeal abnormality was seen on the 3 days follow-up MR imaging. Signal changes caused by blood products which were visible on the MRI images suggested the diagnosis of retropharyngeal hematoma. The patient was conservatively managed

자궁의 해면상혈관종의 자기공명영상 소견: 1예 보고

Hemangioma is the most common soft tissue tumor in the body. Though it may occur anywhere in the body, hemangioma of the uterus is a very rare tumor. Hemangioma is almost asymptomatic, but it is sometimes clinically important because it can cause massive hemorrhage and this is a life-threatening condition. We report here on the magnetic resonance imaging and pathologic findings of cavernous hemangioma of the uterus in a 32-year-woman with menorrhagia. 혈관종은 가장 흔한 연부조직 종양으로 인체 어느 부위에나 생길 수 있지만 자궁 경부나 체부에 생기는 것은 매우 드물다. 증상이 없는 경우가 많지만 때로 과다 출혈을 일으켜 생명을 위협할 수 있다는 점에서 중요한 임상적 의의를 가진다. 저자들은 월경과다를 호소하는 32세 여자 환자의 자궁에 생긴 해면상혈관종 1예를 경험하였기에 자기공명영상 및 병리 소견을 보고하고자 한다.

Hyperechoic Cervical Lymph Nodes after Injection of Silicone into the Face: A Case Report

류지화 대한초음파의학회 2013 ULTRASONOGRAPHY Vol.32 No.4

Lymph nodes (LNs) containing echogenic deposits is a specific ultrasonographic(US) finding of pathologic LNs. Here, I reported on a case of hyperechoic cervicallymph nodes after injection of silicone into the face. US showed globally or partiallyhyperechoic cervical LNs with hyperechoic tapering trails. This is the first descriptionof ultrasonographic findings and the pathologic correlation for LNs affected by migrationof liquid injectable silicone into the neck.

Sinonasal Glomangiopericytoma : A Case Report

류지화,이광희,김지연,김용완 대한이비인후과학회 부산,울산,경남 지부회 2015 임상이비인후과 Vol.26 No.1

Glomangiopericytoma (sinonasal-type hemangiopericytoma) is a rare sinonasal neoplasm, arising from pericytes surrounding capillaries. This tumor accounts for less than 0.5% of all sinonasal tumors. It is a borderline or low grade malignant tumor and a radial surgical resection is considered. The endoscopic and imaging findings are nonspecific. The final diagnosis is based on histopathology and immunochemistry. A 71-year-old woman presented with glomangiopericytoma of the nasal cavity manifestating nasal obstruction and epistaxis. Complete resection of the mass was performed endoscopically. We report herein a case of sinonasal glomangiopericytoma.

정현석,류지화,김동욱,정현경,김홍대,박영미,김수진,김운원,김진수,강태우 대한영상의학회 2011 대한영상의학회지 Vol.65 No.6

Gossypiboma is generally defined as an inflammatory lesion resulting from a foreign substance like a retained surgical sponge or gauze after surgery. Despite a number of reports of gossypiboma after thoracic and abdominal surgery, the gossypiboma after thyroid surgery has quite rarely been reported. We report a case of gossypiboma in the neck after a total thyroidectomy with ultrasonography, computed tomography, and a magnetic resonance image. Gossypiboma는 수술 과정에서 제거되지 않은 거즈나 스펀지 등의 이물질에 의해 발생한 염증성 병변이다. 이는 복부나 흉부 수술과 관련하여서 많은 증례 보고가 있으나, 갑상선절제술 후 발생한 gossypiboma는 매우 드물다. 이에 저자들은 전갑상선절제술 후 gossypiboma를 경험하였기에, 이에 대한 초음파, 전산화단층촬영, 자기공명영상의 소견을 보고하는 바이다.

Spontaneous disappearance of breast calcification has rarely been reported. The majority of cases of spontaneously resolving calcifications have been concerned with benign processes. We report here on breast papillary carcinoma that showed spontaneously resolving microcalcifications without newly developed parenchymal changes on the follow-up mammogram. 유방 석회화의 자연적 소실에 대한 보고들이 드물게 있었지만 이들 대부분은 양성 석회화의 경우였다. 저자들은 추적 유방촬영술에서 새로운 병변의 발생 없이 미세석회화의 자연적 소실만을 보인 유방 유두암의 1예를 보고하고자 한다.

Primary Intraosseous Meningioma in the Orbital Bony Wall: A Case Report and Review of the Literature Review

이성재,류지화,김홍대,이광희,백혜진,김옥화,윤정희,박영미,김동욱,김지연 대한영상의학회 2015 대한영상의학회지 Vol.72 No.1

Meningiomas arising outside the intracranial compartment are known as extradural meningiomas. Extradural meningiomas are rare conditions, accounting for less than 2% of all meningiomas. Primary intraosseous meningioma is used to describe a subset of extradural meningiomas arising from bone. A 46-year-old woman presented with left exophthalmos. Computed tomography and magnetic resonance images revealed an expansile bony lesion in the orbital lateral wall of the left sphenoid bone. The patient underwent craniotomy for excision of the bony lesion. Pathologic examination revealed an intraosseous meningioma.
