About 20 or more cases of seminal vesicle cyst were reported up to nowadays, but CT findings are not yetdescribed. Seminal visicle cyst is often associated with ipsilateral renal agenesis, and the mechanism ofdevelopment is based on embryogenesis. A 26 year old male was confirmed as seminal vesicle cyst in S.N.U.H. inNov. 1981. CT of the seminal vesicle cyst revealed huge, globular and homogeneous mass with well-circumscribedsmooth margin between urinary bladder and rectum. Adilated tubular structure was also found lateral to the hugecystic mass. The ipsilateral kidney was not found in any level of abdomen from the diaphragmetic dome to thesymphisis pubis.

This study was designed to evaluate the potential applicability of magnetic resonance imaging (MRI) for the diagnosis of acute renal vein thrombosis. Renal vein thrombosis was experimentally induced by surgical ligation of the left renal vein in a total of 21 rabbits. MRI was performed with a 0.5 Tesla superconductive magnetic system. Spin echo technique was used with varying TR and TE parameters. Spin echo images of the rabbit kidney were analysed for morphology and signal intensity. T1 and T2 relaxation times of the renal cortex and medulla were calculated from the images. After venous ligation, kidneys became enlarged. Low signal band along the outer medulla in T2 weighted images were characteristically shown from 1 hour to 3 days after ligation, Changes of cortex to medullar contrast (CMC) values were significant (p<0.05) in T1 - and T2- weighted images of the ligated side. T1 and T2 relaxation times were significantly prolonged (p<0.05) on the ligated side, both in the cortex and medulla from 1 hour to 2 weeks after the ligation, while T2 relaxation time on the contralateral side was significantly prolonged both in the cortex and medulla 2 weeks after venous ligation. The most useful MRI criteria for the diagnosis of renal vein thrombosis were enlarged renal size, and the low signal band along the outer medulla of ligated kidney. The relative intensity difference between cortex and medulla (CMC) in T1-and T2-weighted images, and T1 and T2 relaxation times were suggested to be the useful MR parameters for the diagnosis of acute renal vein thrombosis.

Plain chest films are the most useful modality in diagnosis of primary lung cancer, but it is difficult tointerpret the radiologic findings by histological types. Authors reviewed chest films of 324 cases ofhistologically confirmed primary lung cancer from Jan. 1974 to April 1982 at Seoul National University. The resulsare as follows; 1. Incidence was most common in the 6th decade as 34.4%. Male to female sex ratio was 3.8:1 andthere was no sex difference in Adenocarcinoma. 2. Distrubution of histologic types of primary lung cancer asfollows; Squamous cell Carcinoma 50.6%, Small Cell Carcinoma 22.5% lange Cell Carcinoma 9.3% Bronchegenic adenocaranoma 10.5% Bronchioloalveolar Cell Carcinoma 1.9%. Adenosquamos Carcinoma 0,6%, Carcinoid Tumor 0.3%, AdenoidCystic Carcinoma 0.3%. 3. Radiologic findings by histologic types as follows; a) Squamous cell carcinoma commonlypresent as collapse(51.8%) peripheral mass (40.8%), pneumonitis(37.2%), hilar involvement(34.8%), and in singleabnormality, peripheral mass (44.4%). b) Small cell carcinoma commonly present as hilar involvement(78.1%),mediastinal wideing or mass (53.4%) and in single abnormality, hilar involvement(58.3%). c) Large cell carciomacommonly present as hilar involvement(50%) pneumonia(46.7%), collapse (40%), peripheral mass(36.7%) and in singleabnormality, large peripheral mass (33.3%). d) Bronchogenic Adenocarcinoma commonly present as peripheralmass(44.1%), collapse (41.2%), pleural effusion (35.2%) and in single abnormality, peripheral mass(50%). e)Solitary peripheral mass commonly present as lobulation(48%) and spiculated margin (51%), but no specific findingsby histologic types. Cavitary formation was most common in Squamous cell carcinoma.

Authors retrospectively analysed the diagnostic values of oblique tomography of hilum over simple chest PA &AP tomography in 129 cases at Seoul National University Hospital during 3yrs from may 1979 to may 1982. Theresults are as follows; 1. Among 129 cases, 42 cases were lung cancer, 24 cases were tuberculosis, 22 cases wereprominent pulmonary artery, 10 cases were metastasis, & etc. 2. In 42 cases of lung cancer. 1) Diagnostic accuracyof oblique tomography in the evaluation of hilar lymphadenopathy was 92%, that of AP tomography & simple chest PAwere 67% & 54% respectively. 2) Diagnotic accuracy of oblique tomography in the evaluation of endobronchial lesionwas 95%, that of AP tomography & simple chest PA were 24% 14% respectively. 3. It is suggested that in lung cancerif there is no evidence of hilar enlargement in simple X-ray, 55degrees oblique tomography is recommended forevaluation of hilum, or if hilar enlargement is shown in simple X-ray, then AP tomography or CT is recommended forevaluation of mediastinum.

Percutaneous nephrostomy for relief of obstruction and functional preservation of the kidney was effectivelyperformed 19 times in 14 patients for recent 1 year since July 1982 at Departement of Radiology in Seoul NationalUniversity Hospital. The etiologies of the total 14 obstructive uropathies were metastatic cervix cancer in 6-cases, metastatic rectal cancer in 2 cases, and metastatic bladder cancer, malignant mixed mesodermal tumor operimetrium, pyonephrosis, bilateral staghorn stone, UVJ obstruction of undertermined cause, congenital UPJobstruction in 1 case respectively. Percutaneous nephrostomy was done bilaterally in 1 case of congenital UPJobstruction and unilaterally in 13 cases. We used ultrasound as puncture guide in 13 cases and CT in 1 case. Majorcomplication was absent, but minor complications occured in 4 patients; gross hematuria persisting 24 hours (1case), catheter dislodgment after several seeks (2 cases ) and luminal narrowing after 3 months(1 case).Satisfactory outcomes were made in 13 patients except 1 patient who succumbed one day after the procedure due topreexisting severe sepsis. The procedure proved to be safe and effective alternative to operative nephrostomy insome patients with urinary obstruction.

The aim of percutaneous transhepatic biliary drainage(PTBD) is to decrease serum bilirubin level and promoteliver function in patient with biliary tract disease, especially obstruction by malignant disese. But somepatients showed persistent high serum bilirubin level or higher than pre-PTBD level. Percutaneous transhepaticbiliary drainage was performed in 341 patients of obstructive jaundice for 5 years from July, 1981 to July, 1986at departement of radiology, Seoul Natinal University Hospital. Follow up check of the serum bilibrubin level waspossible in 188 patients. Among them the authors analysed 32 patients who showed persistent high serum bilirubinlevel after PTBD. The results were as follows: 1. The male to female ratio was 3.4:1 and the age ranged from 33 to 75. 2. The causes of obstructive jaundice included 30 malignant diseases and 2 benign diseases. Malignant diseasewere 16 cases of bile duct carcinoma, 7 cases of pancreatic cancer and 7 cases of matastasis from stomach, colonand uterine cervix. Benign disease were 1 cases of common hepatic duct stone and 1 case of intrahepatic ductstones. 3. The msot common level of obstruction was trifurcation in 17 cases. 4. The most common indication ofPTBD was palliative drainage of obstruciton secondary to malignant tumor in 28 cases. 5. Change of serujmbilirubin level ratio(post-PTBD level) was 1.28, 1.22, 1.38, 1.51 in serial period of 1–3 days, 4–6 days, 1–2 week 2–3 week after PTBD. 6. Causes of persistent high serum bilirubin level after PTBD were 12 cases of partialdrainage of intrahepatic bile, 13 cases of hepatic dysfunction including 9 cases of metastatic nodule, 2 cases ofbiliary cirrhosis, 2 cases of multiple liver abscess, and 7 cases of poor function of cather including 4 cases ofhemobilia, 1 case of multiple intrahepatic stones, pyobilia and intraheptic Clonorchis sinensis.

The purpose of this paper is to review the colonoscopic fingings of twenty two patients with colonic tuberculosis which were diagnosed by colonoscopic finding, histopathology, and follow-up observation after antituberculosis chemotherapy at Pusan National University Hospital from January 1992 to December 1994. The results were as follows: 1) The male to female ratio was 1: 1.2, and the average age of the patients was 39.4 years with a slight predominance in women. The age of peak incidence was the 4th decade 40.9%). 2) Abdominal pain(95%), diarrhea(63%), and weight loss(50%) were the most common clinical findings. Others were constipation, melena, and palpable abdominal mass. The location of the pain was right lower abdomen, epigastrium, central abdomen, and left lower abdomen in decreasing order. 3) Hematologic findings showed decrease in hemoglobin level, increase in ESR, and positive CRP(61.5%). The white blood cell counts were mostly normal. 4) The stool examination showed positive occult blood in 7 cases among 18 cases (38.9%). Acid-fast bacteria was observed in stool of one case. 5) On colonoscopy, the lesion sites were ileoeecal valve(75%), ascending colon(72.7 %), terminal ileum(52.6%), cecum(42.9%), transverse colon(31.8%), descending colon (27.3%), sigmoid colon(9%), and rectum(9%) in decreasing order of frequency. Most of them involved ileocecal area. 6) On colonoscopy, the shape of ulcer revealed circular(41%), fusion(36%), and irregular pattern(18%). It found skipped area in 9 cases, pseudopolyp in 8 cases, patency of ileocecal valve in 5 cases, and severe deformity of ileocecal valve in 6 cases. 7) Microscopic finding of biopsy specimens revealed noncaseating granulomatous inflammation in 12 cases, and nonspecific ulcerative inflammation in 10 cases. In conclusion the diagnostic yield may be greatly enhanced by obtaining multiple target biopsies frorn tbe deep portion of the ulcer bed and margins. Judged from the colonoscopic finding and clinical improvement after antituberculosis chemotherapy, more accurate diagnosis can be acquired.
