From July 1988 to September 1992, we experienced 15 cases of thrombolysoangioplasty (TLA) at Chonnam University Hospital. Among 15 cases, 5 had claudication (Clinical stage II according to Modified Fontaine Classification), pain at rest (III), and gangrene(IV). Duration of symptoms was 1-7 months except patients of clinical stage IV unable to guess occlusion age. The occlusion length was 5-10cm in 8 cases, 10-20cm in 4 cases, and above 30cm in 2 cases. In all cases, thromolytic therapy was performed with intraarterial urokinase infusion. The total amount of urokinase ranged from 300,000 IU to 2,000,000 IU and infusion time ranged from 2 to 50 hours except three cases infused bolus dose only. Complete successful TLA was defined as technical (less than 50% of residual stenosis) and clinical success. Partial success was defined as technical success but clinical failure. Follow-up angiography could be performed in 8 cases. Overall initial success rate was 86.6% (13/15). Among them. Complete success was in 11 cases and partial success was in 2 cases. Recurrence of disease was not noted on all cases(n=8). Severe complications, such as hemorrhage, did not occurred. TLA was considered to be effective and safe way to recanalized chronic long artery occlusion in lower extremity.

Actinomycosis is an uncommon chronic infectious disease caused by Actinomyces. There are three distinct forms of the condition, namely cervicofascial, thoracic, and abdominal; the hepatic variety is an unusual form of abdominal actinomycosis, accounting for about 15% of cases of this type. Many reports of actinomycosis have been published, but few have detailed the MR findings of hepatic actinomycosis. We describe the contrast-enhanced CT and MR findings in one case of hepatic actinomycosis.

PURPOSE: The main aim of this study was to compare spiral CT and MR imaging in the detection and characterization of focal hepatic masses. MATERIALS AND METHODS: Seventy-nine patients with 155 focal hepatic masses confirmed pathologically, or radiologically and clinically [hepatocellular carcinoma(HCC) (n =52), hemangioma (n=36), cysts (n =35), metastasis (n =27), intrahepatic cholangiocarcinoma (n =5)], underwent two- or three-phase spiral CT, and T1-, T2- weighted, and dynamic contrast-enhanced MR imaging. The detection and characterization of focal hepatic masses by these modalities were evaluated and compared. RESULT: The detection rates of spiral CT and MR imaging, respectively, were as follows: HCC, 81%(42/52) and 94%(49/52); hemangioma, 75%(27/36) and 100%(36/36); cysts, 80%(28/35) and 100%(35/35); metastasis, 67%(18/27) and 100%(27/27); and intrahepatic cholangiocarcinoma, 100%(5/5) and 100%(5/5). MR imaging was superior to spiral CT in mass detection of HCC, hemangioma, cysts, and metastasis (p < .05). The characterization rates of spiral CT and MR imaging, respectively, were as follows: HCC, 52%(27/52) and 71%(37/52); hemangioma, 67%(24/36) and 100%(36/36); cysts, 63%(22/35) and 100%(35/35); metastasis, 37%(10/27) and 100%(27/27); and intrahepatic cholangiocarcinoma, 40%(2/5) and 80%(4/5). In the mass characterization of HCC, hemangioma, cysts, and metastasis, MR imaging was superior to spiral CT (p< .05). CONCLUSION: In the detection and characterization of focal hepatic masses, including hepatocellular carcinoma, hemangioma, hepatic cyst and metastasis, MR imaging is superior to spiral CT.

Malignant lymphoma can involve the cardiac cavity or myocardium as a mass. Clinical symptoms of its cardiac involvement are usually absent or nonspecific, making the diagnosis of the cardiac involvement very difficult before death. We experienced a patient with secondary myocardial non-Hodgkin's lymphoma presenting with sustained ventricular tachycardia (VT) as a primary clinical problem. A 39-yr-old woman visited our hospital because of dyspnea and palpitation for 7 days. Physical examination revealed rapid heart beat with variable intensity of the first heart sound and soft mass in the lower abdomen. VT with a cycle length of 480 msec was recorded in resting 12-lead electrocardiogram. Two well-circumscribed hypo-echogenic round masses were demonstrated in the interventricular septum and left ventricular posterior wall. Cytological examination of aspirated pericardial fluid and percutaneous needle biopsy of the abdominal mass revealed a diffuse large cell type non-Hodgkin's lymphoma. Myocardial masses and ventricular tachycardia resolved with chemotherapy using cyclophosphamide, adriamycin, vincristine and prednisone regimen. To our best knowledge, the same case as ours has not been reported previously.
