Percutaneous transhepatic intervention for removal of common bile duct stones is introduced as a secondary choice of treatment in the high-risk patient. Through a percutaneous transhepatic biliary drainage catheter, a Dormia basket was inserted and the stone was entraped. Then the stone was crushed and fragments were passed spontaneously to the duodenum through the Ampulla of Vater. We experienced one case of successful treatment of a common bile duct stone using percutaneous transhepatic insertion of the Dormia basket.

We reviewed the magnetic resonance imaging (MRI) of intracranial teratoma to detect the characteristic findings. Five patients with intracranial teratoma were evaulated with MRI from January 1988 to December 1990. Four male and one female patients with age ranging from 6 to 14 years were surgicelly confirmed. MRI was done with 2.0T superconducting system (Spectro 20000, Goldstar, Seoul)and gadolinium enhancement was done in 4 patients. We retrospectively reviewed the clinical, operative, pathologic, and radiologic findings. Intracranial teratomas showed fatty component, calcification and cystic component filled with sebum or serous fluid. Peripheral rim enhancement was seen in three and irregular enhacement in two cases. There were hydrocephalus in all pineal teratoma, but neither surrounding edema nor surrounding tissue invasion was seen. Low signal intensity rim was noted around the solid component of all tumors and they were not enhanced. MRI showed multicomponent of intrac anial teratoma including the solid and cystic component, and low singal rim which might be the characteristic finding of the intracranial teratoma.

Hepatic tumors include a broad spectrum of benign and malignant neoplasms. Hepatocellular carcinoma (HCC) is frequent malignancy in Korea, and its diagnosis is usually done by radiological studies. But other hypervascular lesions can mimic the radiological findings of HCC. So, it is important to know the decisive radiological findings for differential diagnosis to avoid inappropriate decisions based on misdiagnosis. In this article, the imaging features of the liver masses including hemangioma, adenoma, focal nodular hyperplasia, peliosis, and other miscellaneous tumors will be presented, and the points to distinguish between benign and malignant hepatic lesions will be discussed.

Purpose : Tumor vascularity is useful for characterizing tumors and determining tumor management. The recent development of power Doppler sonography has enhanced the sensitivity in the detection of blood flow. In addition, use of contrast agent in Doppler sonography makes it much easier to depict the tumor vascularity. The purpose of this study was to evaluate the efficacy of contrast agent in power Doppler sonography in demonstrating tumor vascularity of VX-2 carcinoma. Materials and methods : Power Doppler sonography was performed on VX-2 carcinnoma in the rabbit things. Contrast enhancement ratio was measured in each rabbit from 5 to 180 seconds after contrast injection. For quantitative analysis, percentages of tumor vascular area per tumor area on each case were measured. Results : The contrast enhancement ratio were significantly increased from 10 to 180 seconds after injection of contrast agent in all rabbit. The mean percentages of tumor vascular area per tumor area were 5.07% on non-enhanced scan, and 10.97% on maximum contrast-enhanced study. Conclusion : Contrast-enhanced power Doppler sonography can demonstrate the tumor vascularity better than non-enhanced scans. However, it tends to overestimate the tumor vascularity.

Tuberculosis and lymphoma, these 2 diseases can present with lymphadenopathy in anywhere of the body. Therefore differentiation of tuberculosis from lymphoma is often difficult. CT scans of 17 patients with tuber-culosis and 23 patients with lymphoma were retrospectively reviewed to evaluate the efficacy of CT scans in differentating adenopathy between tuberculosis and lymphoma. All the patients underwent abdominal CT scans with contrast enhancement before treatment. The size, internal architecture, distribution of lymph nodes, and associated findings on CT scans were analyzed. As compared with lymphoma, tuberculous lymphadenopathy showed 1) female preponderance (65%), 2) predilection for portocaval lymph nodes (47%), 3) internal low attenuation in lymph nodes(82%) 4) cold absecss formation (24%) Characteristics of lymphoma on CT scans included 1) male prepondrance (78%) 2) conglomeration of lymph nodes (39%) 3) homogeneous internal lymph node structure (83%) These results suggest that evaluation of the characteristics of lymphadenopathy on CT scans is helpful for differentiating between tuberculosis and lymphoma.
