Authors compared early phase scan of the IV bolus CT (two phase incremental bolus dynamic CT) with late enhanecd scan similar to the conventional contrast enhanced CT for evaluation of the advantages of the IV bolus CT with two viewpoints of the pancreatic or peripancreatic mass and peripancreatic lymphadenopathy in 68 patients-28 cases of the pancreatic cancer, 6 cases of the pancreatitis and 34 cases of the pancreatic or peripancreatic metastasis. On the diagnosis of the pancreatic or peripancreatic mass, IV bolus CT could show the lesion(s) more easily in 41% (Grade II; 13/31) and much more easily in 34% (Grade III; 10/31) when compared with conventional contrast CT scan. The diagnosis of the peripancreatic lymph node involvement was also easy in 51%(Grade II; 20/39) and much easier in 37% (Grade III; 14/39). We thought that these differences were originated from the increase of the contrast between the lesion and normal portion because the early enhanced scans reflected the active blood flow change more exactly. Therefore IV bolus CT had advantages in comparison with the conventional drip infusion contrast CT in the diagnosis of the presence and pathologic extension of the pancreatic and peripancreatic lesion.

We performed IV bolus CT scan in 40 patients with final diagnosis of various hepatic masses in order to evaluate hemodynamic changes and differentiating characters of the lesions. Preenhanced, early and late phase post enhanced, and delayed CT scans were obtained with rapid IV bolus injection of contrast materials and table sliding method for pertinent scans. In hepatomas, early enhanced CT scan directly showed hypervascular change and active viable portion of the mass and late phase CT scan showed capsular enhancement. In addition, extracapsular invasion and post-embolization recurrence were more easily visualized. In hemangiomas, early and late enhancing types could be categorized according to the time of maximal enhancement. In metastatic liver malignancies and cholangiocarcinomas, specific findings were seen in early phase and delayed CT scans and not in conventional CT scan. In conclusion, IV bolus CT scan is a very useful CT method in demonstrating the characteristic hemodynamic patterns and in differential diagnosis of the hepatic masses.

Failed Back Surgery Syndrome*

Neurofibromatosis(NF) is a disorder characterized by its relative commonness, variability, and heterogeneity. It is usually expressed as a generalized form, but is rarely localized in a limited part of the body as a segmental form. In 1981, Riccardi classified NF into 8 types and a segmental form (type V) was defined by limitation of cafe-au-lait spots and/or neurofibroma on a given unilateral segment of the body. Recently we came across two cases of typical segmental neurofibromatosis. The First case was a 53-year-old woman with localized neurofibromatosis on the right T8,9 dermatome. The Second case was a 34-year-old man with localized neurofibromatosis on the right T5,6 dermatome. There were no cafe-au-lait spots, axillary frecklings, Lisch nodules or a family history in both cases. We report these rare cases with a literature review.

The transarterial embolization has been widely used to control bleeding. It has a variety of clinical utility; to reduce bleeding on the surgical field, to reduce the size of malignant tumor as a preopearative treatment, to treat arteriovenous malformation or arterial aneurysm as a curative method and to promote life qua' ity of patient with diffuse or multiple hepatocellular carcinoma as a palliative treatment, etc. With the advance of modem technology, various embolic materials have been also developed. IIowever, it has not- been -fully investigated of histopathologic changes of the embolized organs according to the embolic materials used. This study was undertaken to investigate the histopathologic changes of embolized renal artery in rabbit by various embolic materials, according to each embolic material and to time passed by after embolization. Of the 5 arteries embolized by ethylene vinyl alcohol copolymer(EVAL), one showed abscess formation in embolized kidney. The other 4 allowed to perform further pathologic study: within a week after embolization there was no any specific change in vessels, however, r,unimal endothelial hypertrophy was observed following 2 weeks of embolization. Of the 8 renal arteries embolized by N-buthyl-2-cyanoacrylate(Histoacryl), 4 showed total occlusion of the main renal arteries as well as renal infarction, which reflects the strong adhesiveness of Histoacryl to vascular wall. The other 4 showed fibrinoid degeneration in vascular wall within a week. However, further change was not observed thereafter. In all the 5 renal arteries embolized by polyvinyl

The fibromatosis is a rare timorous with local invasion, but is not metastasized distantly. This term should not be applied to nonspecific reactive fibrous proliferations that are part of an inflammatory process of are secondary to injury of hemorrhage and have no tendency toward growth or recurrence. It arises principally from the connective tissue of muscle and overlying fascia or aponeurosis (musculoaponeurotic fibromatosis), and chiefly affects the muscle of shoulder, pelvic girdle, and extremity. The term 'aggressive fibromatosis' is also employed to describe this disease, but it is impossible to predict the clinical course in the individual case. The fibromatosis arising in the mediastinum is very rare, and the report about it is nearly absent. The plain radiography shows merely mass with soft tissue density. The CT demonstrates a poorly defined homogenous or heterogeneous mass, isodense with skeletal muscle on precontrast-images, and slightly hyperdense to muscle on postcontrast-scan. Accurate delineation between the tumor & surrounding tissue is vague or frequently impossible. The authors experienced one case of the mediastinal fibromatosis recently and report the case with review of concerned literature.
