Utrerine myoma is one of the most commonly encountered gynecologic problem in daily ultrasonographic practice,and is one of the few conditions with which specific histologic diagnosis is possible by ultrasonography in selected patients as well. We recently analysed ultrasonograms of 132 cases of uterine myoma and 31 cases thatshowed similar ultrasonographic findings of myoma, histopathologically verified in both cases. The results were as follows. 1. The diagnostic accuracy by ultrasonography was 93%. 2. The most common ultrasonographic findings of uterine myoma were nodular enlargement of uterus and irregular internal echo texture changes. 3. It was not possible to differentiate the various kinds of secondary degeneration by ultrasonography, except for calcification and cystic change. 4. It was usually unable to differentiate solitary from multiple myoma, and subserosal,interstitial and submucosal types from each other by ultrasonographic findings alone, except for the usual cases of exophytically growing subserosal mass. 5. The most frequent disease that is hard to differentiate from small uterine myoma was adenomyosis, and therefore it is considered necessary to include the adenomyosis in differential diagnosis in the diagnosis of myoma causing moderatelly enlarged uterus.

Eighty-eight patients who presented with a variety of head and neck symptoms were examined with intravenous oritraarterial digital subtraction angiography (IV or IA DSA), using the DSA equipment developed by Seoul NationalUniversity Hospital. A grading system was used to evaluate the ability of DSA to answer specific diagnsoticquestions. Diagnostic information without need of further study was obtained in 71% with IV DSA, in 86% withaortic arch DSA and in 81% with selective arterial DSA, showing a total of 79% of diagnostic accuracy with DSA. Itis concluded that IV DSA is useful in the evaluation of the cervical carotid and vertebral arterial disease, andpituitary mass lesion, while IA DSA is useful in the evaluation of the cervical carotid and vertebral arterialdisease, and pituitary mass lesion, while IA DSA is useful in the evaluation of most of the intracranial lesions,spinal arteriography and intra-arterial embolization. DSA is both an accurate and safe imaging modality in thestudy of head and neck diseases.

CT is the most accurate and reliable method for the diagnosis of intracerebral and intraventricularhemorrhage. The precise anatomic extent of the hematoma, associated cerebral edema, ventricular deformity anddisplacement, and hydrocephalus are all readily assessed. Aside from head trauma, the principal cause ofintracerbral hematoma is hypertensive vascular disease. Although hematomas from various causes may present similarCT appearances frequetnly the correct etiology may be suggested by considereation of patient's age, clinicalhistory, and the location of the hematoma. The analytical study was performed in 180 cases of intracerebralhamorrhages by CT from Oct. 1981 to Jan. 1983. The results were as follows; 1. The most prevalent age group was6th decade(37.2%) Male was prevalent to female at the ration of 1.6 to 1. 2. The most common symptom and sign wasmental distrubance (48.7%), motor weakness(23%), headache(10.6%), nausea and vomiting (9.8%). 3. The causes ofhemorrhage were hypertension (53.9%), head trauma (30.6%), aneurysm(6.1%) and A-V malformation (7.2%). 4. Thefrequent locations of hemorrhage were basal ganglia and thalamus(40.4%), lobes(35%), ventricles(21.8%). 5. Thedistribution of hemorrhage was intracerebral hemorrhage(65.6%), intracerebral and intraventricularhemorrhage(30.3%), intraventricular hemorrhage(4.4%).

Amipaque is a water soluble, non-ionic myelographic contrast media, and owing to its high diagnostic accuracy and safety, its use is gradually increasing. The authors studied the complications after Amipaque lumbermyelography in 61 patients with low back pain during the period from Jan. 1981 to Nov. 1981 in Chung Ang University Hospital. The results were as follows; 1. Total complication rate was 52%(32 of 61) and there was nosexual difference in its occurrence. 2. In total, no difference in complication rate was found between head-up positioned group with a degree of 30degrees (group I) after procedure and head-up positioned group with a degree of 70degrees (group II) but female patients had more complication rate in group I than in group II (75% vs 50%).Headache was more common in group I and nausea was more common in group II. 3. Headache was most common complicaiton (44%) and there was no sexual difference in its occurrence. 4. No significant difference in complication rate was found between patients proved to have HBP and patients to have not. 5. Complications were less common in patients with punctured level of L4-5 than in patients with L2-3 or L3-4 level puncture.

Opacification of the gallbladder after parenteral administration of contrast material usually indicates diminished renal function but can occur with normal renal function. The authors recently experienced 13 cases of such vicarious excretion of contrast media. Among 13 patients. 9 patients had renal disease unilateral ureteral stone(n=3), staghorn calculi(n=2), acute renal failure from sepsis(n=1), renal contusion(n=2) and unilateral renal artery involvement by dissecting aortic aneurysm(n=1). Of these 9 patients, 3 patients showed abnormal serum creatinine levels at the time of presentation or shortly thereafter. In 6 patients, injection of a large amount of contrast media was possibly the additional cause of vicarius excretion. There was no detectable cause in the remaining 4 patients. Heterotopic excretion of contrast media is clearly a complex phenomenon, the reason for which it is difficult to establish with certainty in each individual case. Anyhow, vicarius excretion of contrast media occurs more frequently than previously thought, and it can occur not only with abnormal renal function but with normal function also.

Transcatheter arterial embolization was applied in 7 cases of hepatic disease including hemobilia of various causes and malignant tumors at Department of Radiology, Seoul National University Hospital during recent several years. The embolic materials were autologous blood clot and Gelfoam particle. Successful control of bleeding or devascularization of tumor vessel was made in 6 of the 7 patients. There was no serious complications; however, post embolization syndrome was found including pain, fever, nausea and vomiting in all cases and subsided after a few days. Transcatheter hepatic arterial embolization is suggested to be a safe and effective treatment in control of hemobilia and devascularization of malignant hepatic tumors.

Obstruction of the inferior vena cava(IVC) is an uncommon condition, and the collateral pathway variesaccording to the level, extent, duration and the cause of obstruction. Membranous obstruction of IVC in itshepatic portion might be one of the principal cause among Korean, though not reported till now. Analytical studywas perfomred in 26 cases of IVC obstruction with various cause. 1. The level of the obstruction showed relativelyeven distribution as follows, upper caval in 11 cases, middle caval in 6 cases and infrarenal in 9 cases. 2. Themain cause of upper caval obstruction was membranous obstruction . 3. As a whole, the main collateral pathway wasthe central route(22 case:85%). 4. Characteristic collateral pathway unique to upper caval obstruction wastranshepatic vanous collateral, developed between the obstructed segment and unobstructed segment of IVC. 5.Scalloping of left cardiac border produced by pericardiophrenic venous collateral was characteristic simple chestX-ray finding in IVC obstruction.

PURPOSE: The purpose of this study is to assess the effect of Transcatheter Arterial Embolization(TAE) according to anglographic findings in hepatocellular carcinoma. MATERIALS AND METHOD: We retrospectively reviewed 50 cases who received TAE for unresectable hepatocellular carcinoma. We analyzed the anglographic findings which were correlated with the effect of TAE. The common anglographic findings of the hepatocellular carcinoma were tumor staining, neovascularity and enlargement of feeding artery. These anglographic findings were classified into grade 0, +1, +2. Effect of TAE were classified into five patterns;good response, partial response, minimal response, no response and more aggravation. RESULT:In grading of tumor staining, among 50 cases, the grade 0, +1, +2 were seen in 1 case(2%), 14 cases(28%), 35 cases(70%) each. In grading of enlargement of feeding artery, the grade 0, +1, +2 were seen in 7 cases(14%), 19 cases(38%), 24 cases(48%) each. In grading of neovascularity, the grade 0, +1, +2 were seen in 6 cases(12%), 15 cases(30%), 29 cases(58%) each. This study showed that the higher grade of anglographic finding, the better effect of TAE. A statistically significant differance was found (p<0.005). But the TAE was not effective in some cases (the maximum diameter of mass is over 10cm, portal vein thrombosis or ateriovenous shunt) in spite of high grade. CONCLUSION: We believe that these angiogr. aphic findings (tumor staining, enlargement of feeding artery, neovascularity) are one of important indices for anticipating the effect of TAE in patients with unresectable hepatocellular carcinoma.
