Primary paraganglioma of the liver is a very rare disorder, and radiologic findings have not yet been described. We report a case of this entity in which the US, CT, MRI and 131I-MIBG scan findings are described.

The VATER syndrome is defined as a non-random association of congenital anomalies including three or more of vertebra(V), anal(A), tracheoesophageal(TE), and radial or renal(R) deficiencies. We experienced two cases of VATER syndrome; one is a 2-year-old male having imperforate anus. V-U reflux. polydactyly and secondary ASD and another one is a 17-year-old Female having lumbar scoliosis, imperforate anus, renal agenesis and didelphy uterus with ovarian cystadenoma.

Echocardiography was done on 51 cases with various cardiovascular disease and on 23 cases of normal control subjects from April, 1981 to March, 1982 in the Department of internal medicine, Eul Ji General Hospital, Seoul, Korea. The results obtained were as follows: 1. The left ventricular mass estimated by the measurements made with standard convention was 261+/-8gm in patient group and 126+/-6gm in control group. With penn convention, the left ventricular mass of the patients group was 297+/-11gm and that of control group was 127+/-6gm. The differences between both conventions were significant statistically. 2. In measurements made with standard convention, those who showed increased left ventricular posterior wall thickness were 37 cases(73%) and those who showed increased left ventricular internal dimension were 15 cases(29%). On the other hand, number of cases who showed increased left ventricular mass were 45 cases(88%) and this results suggested estimation of left ventricular mass seems to be more useful method in the diagnosis of left ventricular hypertrophy than simple measurements of left ventricular posterior wall thickness of left ventricular internal dimension. 3. The correlation coefficient between left ventricular mass and maximum voltage of electrocardiography, left ventricular posterior wall thickness left ventricularinternal dimension was 0.70, 0.74 0.51 respectively in standard method and 0.82, 0.76, 0.44 respectively in penn convention. Left ventricular mass was correlated fairly closely with the maximum voltage of electrocardiography and left ventricular posterior wall thickeness, less closely with the left ventricular internal dimension.

PURPOSE: To determine the different of enhancement patterns of hepatic hemangioma according to the lesionsize, using dual-phase spiral CT. MATERIALS AND METHODS: Fify-nine lesions in 45 patients with hepatichemangiomas were subjected to spiral Ct. According to size, the lesions were divided into two groups(< 2.5cm :n=34 ; >_2.5cm : n=25). The enhancement patterns of the lesions were classified as one of four types (homogeneoushyperdense, peripheral hyperdense, central hyperdense, or hypodense) during the early phase, and as one of fivetypes homogeneous hyperdense, peripheral hyperdense, central hyperdense, hypodense or isodense) during the delayedphase. We evaluated differences in enhancement patterns during the early and delayed phase according to lesionsize. RESULTS: During the early phase, the enhancement patterns of lesions large than 2.5cm were peripheralhyperdense(96%) or homogeneous hyperdense (4%);those of less than 2.5cm were peripheral hyperdense (53%),homogeneous hyperdense(26%), hypodense(18%), or central hyperdense(3%). Thus, hemangiomas in these two groupsusually showed a peripheral enhancement pattern during the early phase, but in those which were smaller than2.5cm, atypical enhancement patterns were more common. During the delayed phase, the enhancement patterns oflesions larger than 2.5cm were peripheral hyperdense (60%) or homogenous hyperdense (40%), while the patterns ofthose smaller than 2.5cm were homogeneous hyperdense (67%), peripheral hyperdense (24%), central hyperdense (3%),hypodense (3%), or isodense (3%). Thus, the enhancement patterns of lesions larger than 2.5cm were usuallyperipherally hyperdense during the delayed phase, while those smaller than 2.5cm showed a homogeneous enhancementpattern. CONCLUSION: The enhancement patterns of hepatic hemangiomas differ according to lesion size. A knowledgeof these differences is helpful in the diagnosis of hepatic hemangioma.

PURPOSE: To evaluate the US findings of epididymal adenomatoid tumor. MATERIALS AND METHODS: Were trospectively reviewed US findings of four patients with histopathologically proven epididymal adenomatoidtumors. Lesions were evaluated for their size, location, margin, shape and echogenicity. RESULTS: The size of thetumors ranged between 0.5cm and 2cm and all occurred on the left side of the epididymis. Of the four cases, three were located at the tail of the epididymis and one at its head. The tumors were well marginated and spherical andecho-texture was variable but homogenous. CONCLUSION: The possibility of and adenomatoid tumor should be considered when the epididymal mass is round and has a clear margin and the echo-texture of ultrasound ishomogenous.

PURPOSE: To determine the enhancing patterns of hepatocellular carcinoma(HCC) and the difference of enhancing patterns according to the tumor size, using spiral CT. MATERIALS & METHODS: We reviewed 213 lesions in 76patients who had been clinically or histopathologically diagnosed as HCC sufferer. The tumors were divided into three groups, according to size(&3 cm, 3-5cm and >5 cm). The enhancing patterns of tumor and capsule in the earlyand delayed phase were analysed. The enhancing patterns of the tumor were divided into five types(high, peripheralhigh, mixed, iso and low attenuation) in the early phase and four types(central high, mixed, iso, and low attenuation) in the delayed phase. The enhancing patterns of the capsule were divided into three types such asiso, low and high attenuation. RESULTS: High attenuating lesions in the early phase were as follows : below 3cm 72% ; 3-5cm., 60% ; above 5cm., 49%. Mixed attenuating lesions in the early phase were as follows : below 3cm., 1%; 3-5cm., 22% ; above 5cm., 36%. Thus, most HCCs were high attenuation type in the early phase, but as the tumorbecame larger, less high attenuation and more mixed attenuation was demonstrated(p<0.01). There was no difference of enhancing patterns according to the tumor size in peripheral high, iso and low-attenuating lesions. In the delayed phase most of the hepatomas appeared as totally hypodense lesions. For capsules, the results were as follows : below 3cm., 20% ; 3-5cm.,58% ; above 5cm., 73%. As the tumors became larger, more capsules were demonstrated(p <0.01). The capsules were visualized as iso or low attenuating rim in the early phase and high attenuating rim in the delayed phase. CONCLUSIONS: To determine the enhancing patterns of HCC using spiral CT is considered to be helpful in the diagnosis of HCC.
