This study was an analyses of blood supply of the liver in 125 patients who received hepatic arteriography and abdominal aortography from Jan. 1984 at the Dept. of Radiologyof Hanyang Univ. Hosptial. A. Variations in extraheptic artery pattern occured in 106 of 125 cases.; Right hepatic and left hepatic arteries arising from the hepatic artery proper and heaptic artery proper arising from the common hepatic artery. 2. The most common type of variation of extrahepatic artery was replaced right hepatic artery from superior mesenteric artery : 6 of 125 cases. B. Variatonsin intrahepatic arteries 1. The normal intrahepatic artery pattern occurred in 83 of 125 cases.: Right hepatic and left hepatc arteries arising from the hepatic artery proper and middle hepatic artery aising from lower portion of the umbilical point of left hepatic artery. 2. The most common variation of intrahepatic arteries was middle hepatic artery. 3. Among the variation of middle hepatic artery; Right, middl and left hepatic arteries arising from the same location at the hepatic artery proper was the mostcommon type; 17 of 125 cases.

Lots of recent technical advances in radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC) have introduced. First, contrast-enhanced ultrasound can help to detect the index tumors, residual tumor, and local recurrence. After contrast-enhanced ultrasound for subtle small tumors, we can perform RFA with high confidence. The use of artificial ascites in RFA is a simple and useful technique to minimize collateral thermal injury and to improve the sonic window. Fusion imaging between US and CT or MR during RFA is useful since US can provide real-time imaging and CT or MR provides high quality images with good contrast and spatial resolution. RFA can be performed with fluoroscopy guidance to lipiodol retention tumors.
Henoch-Sch$\"{o}$nlein 자반증 환아에서 동반된 공장-공장형 장중첩증 1례

저자들은 복부 통증 및 구토를 주소로 내원한 HSP를 진단받은 5세의 남아에서, 복부 초음파 검사를 통해 공장-공장형 장중첩증을 진단하였으며 그 후 자연감압으로 증세가 호전되었고, 복부 전산화 단층 촬영 검사로 자연정복되었음을 확인한 환아 1례를 경험하였기에 보고하는 바이다. Gastrointestinal involvement occurs in two thirds of children with Henoch-Sch$\"{o}$nlein purpura (HSP) and intussusception is by far the most common abdominal complication. Intussusception in HSP almost originates in the small bowel, which is in contrast with idiopathic intussusception. Earlier diagnosis and prompt treatment of intra-abdominal complications can reduce the mortality and ultrasound is the imaging modality of choice in evaluation the bowel manifestations of HSP. We report a case of jejuno-jejunal intussusception associated with HSP in a 5-year-old boy who presented with diffuse abdominal pain and vomiting after a few days of HSP onset. Abdominal ultrasound demonstrated intussusception in the jejunum with well defined target appearance because of the thickened intussusceptum, which disappeared on the computerized tomographic examination checked approximately 24 hours later. A brief review of literature was made.

Cerebral primitive neuroectodermal tumor (PNET) is a neoplasm of children and young individuals that occurs predominantly in the supratentorial compartment. It is a diagnosed as a genetic term for cerebellar medulloblastomas and for neoplasm which are morphologically indistinguishable from the medulloblastoma but are located at other sites in the CNS. In this report, we retrospectively reviewed and analyzed 7CT and 2 MR findings in 7 patients with pathologically-proven PNET or radiologically characteristic PNET findings. The most characteristic features of the PNETs was a well-defined oval or round large mass with/without intratumoral calcification and hemorrhage in the cerebral hemisphere, especially in the parietal and frontal lobe. There was only minimal surrounding edema. The CT and MR findings demonstrated solid portion and cystic area but mainly enhanced in the solid portion.

The hepatoid adenocarcinoma is a rare extrahepatic primary neoplasm showing similar histopathologic features of primary hepatocellular carcinnoma and usually produce a large amount of alpha-fetoprotein hepatic type. There ate several pathologic and radiologic reports of adenocarinoma of stomach, lung, pancreas, gallbladder, bile duct, ampulla of Vater, renal pelvis arid urinary bladder. Authors report a case of biopsy-proven hepatoid adrnocarcinoma of the duodenum.

두개인두종은 소아에서는 전형적으로 안상병번 (suprasellar lesion)으로서 관찰되나 성인에서는 비전형적인 위치에서 자주 관찰된다. 조직학적으로는 크게 에나멜 형 (adamantinous type)과 인유두형(squamous papillary type)으로 구분되며 같은 에나멜형 일지라도 소아와 성인간에 조직학적 차이가 다소 있고 인유두형은 소아연령에서는 거의 발견되지 않는다. 이러한 병리조직학적 관점에서 볼 때 이들간의 방사선학적 검사소견의 차이를 이해할 수 있으며 정확한 진단과 예후판정에 도움을 줄 수 있으리라 생각한다. 저자들은 남자 성인의 사상하부에서 발생한 인유두형의 두개인두종 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Thrity one lymph njodes in thirty follow-up CT studies in 9 patients with a diagnosis of malignant lymphoma were reviewed to determine the efficacy of CT studies for determining response of the therapy. In these 9 patients, CT findings are subdivided to 5 groups by the gross appearances of lymph nodes; (a)complete disappear, (b)multiple strands, (c)decreasd size without changes in internal characteristics, (d)decreased size with central low density, (e)increased size. Clinical correlation preceding the follow-up CT examination was obtained and it's correlation was very excellent. The group (a) to (d)were matched with good clinical course and group (e)was matched with poor clinical course. The appearances of the lymph nodes were not correlated with the histologic cell types and methods of therapy. The CT examination is satisfactory in the post-therapy follow-up of lymphoma patients.
