We experienced a case of Takayasus arteritis with eclampsia in a 43-year-old woman. The patient had angiographically definite Takayasus arteritis with the involvement of right common and internal carotid arteries. On MR images performed at clinical manifestations of eclampsia, unilateral involvement of T2 high signal intensities were demonstrated in right cerebral hemisphere. We report this case with a literature review.

PURPOSE:The purpose of this study is to evaluate the change of pancreatic size after gastric resection in patients with gastric malignancy. MATERIALS AND METHODS: We compared the pancreatic sizes on pre- and post-operative abdominal CT scans in 50 patients whose stomach had been resected due to malignancy. The mean interval was 20.3 months (range, 5-81 months). The types of the operation were total gastrectomy with esophagojejunostomy and jejunojejunostomy (n=7), and subtotal gastrectomy with gastrojejunostomy (Billroth II) (n=43). Pancreatic thickness was measured perpendicular to the pancreatic long axis at head, body and tail. RESULT: There was a significant reduction of pancreatic size on postoperative CT scan. The reduction rate was 5.9% in the head (p<0.001), 7.1% in the body (p<0.001) and 14.4% in the tail (p<0.001). CONCLUSION:Significant reduction of pancreatic size was observed after gastric resection due to gastric rnalignancy, especially in tail.

PURPOSE: We aimed to know the prevalence of abnormal meniscal signal on MR imaging in asymptomatic soccer players and its radiologic significance. MATERIALS AND METHODS: Using T1 and gradient echo T2* weighted sagittal and coronal MR image, 48 knees in twenty-four full time soccer players were evaluated for the meniscal abnormalities, the status of ligament and existance of joint effusion. Meniscal abnormalities were interpretated using grading system of Lotysch. By using Chi-square method, We analyzed the existance of joint effusion could divide the healing state and healed state of the meniscus. RESULTS: The prevalence of Grade 2 and more and Grade 3 were 42% and 39% of asymptomatic knees. In the 24 knees with meniscus tear, nine of the 14 asymptomatic knee showed effusion while eight of the 10 symptomatic knee did. Of 24 knees with meniscal tear, only eleven knees were related to previous history of major knee trauma. CONCLUSIONS: The prevalence of meniscal abnormalities on MR imaging in asymptomatic soccer players was higher(grade 3:39%) than we expected. The joint effusion was not helpful to divide the healing state and healed state of the meniscus. So we suggest baseline MR imaging in the athletes who have been using the knee vigorously could give decisive information for the interpretation of subsequent MRI that may be performed when the players wounded.

We experienced a rare clinical manifestation of a digoxin induced catatonic stupor without other features of digoxin toxicity. This case suggests that the neurological manifestation of digoxin toxicity can occur without the usual side effects. Also, a serum digoxin level should be checked in any elderly patient presenting with abnormal cerebral func-tions, irrespective of whether or not the dose of digoxin has been changed.

Pericarotid syndrome is the combination of a postganglionic Horner's syndrome and ipsilateral head and facial pain, which is caused by diverse pathologic processes in and around the internal carotid artery. We report a case of peri-carotid syndrome which presented Horner's syndrome and ipsilateral periodic severe hemicrania associated with malig-nant lymphma lapping internal carotid artery. After surgical removal of the mass and chemotherapy, miosis, ptosis, and ipsilateral hemicrania improved.

BACKGROUND: Progressing stroke (PS) variably develops from initially the same size and severity, and is most frequently observed in lacunar infarctions. We investigated fractional anisotrophy (FA), mean diffusivity (MD) and infarct volume by using diffusion tensor imaging during the acute phase of ischemic stroke to determine whether these parameters are useful in characterizing and predicting PS. METHODS: In this study, 55 consecutive patients admitted within 24 hours of the onset of their first ischemic stroke were included. NIH stroke scale (NIHSS) and Canadian Neurological scale (CNS) were performed upon admission, twice a day, and at discharge. Modified Rankin scale and Barthel index were also evaluated. PS was defined as a 2-point drop in NIHSS and a 1-point drop in CNS from admission to day 3. A correlation analysis was performed between clinical scale scores and imaging parameters, and the distribution of those values was compared between the two groups with and without PS. RESULTS: Significant correlations were observed between clinical scale scores and infarct volumes. The FA ratio in 14 patients with PS was lower than the patients without PS (p=0.004). Other characteristics including infarct volume and MD ratio were not different. The FA ratio remained as an independent predictor of PS (OR, 1.055; p=0.011). CONCLUSIONS: In acute ischemic stroke within the first 24 hours, only infarct volume was correlated with clinical status. However, patients with PS showed lower FA values, which accounts for rapid and severe vasogenic edema involving the disruption of the cell membrane and axonal fibers. Moreover, FA may be a predictor of PS.

Mild cognitive impairment (MCI) has been defined as a transitional state between normal aging and Alzheimer disease. Diffusion tensor imaging (DTI) can estimate the microstructural integrity of white matter tracts in MCI. We evaluated the microstructural changes in the white matter of MCI patients with DTI. We recruited 11 patients with MCI who met the working criteria of MCI and 11 elderly normal controls. The mean diffusivity (MD) and fractional anisotropy (FA) were measured in 26 regions of the brain with the regions of interest (ROIs) method. In the MCI patients, FA values were significantly decreased in the hippocampus, the posterior limb of the internal capsule, the splenium of corpus callosum, and in the superior and inferior longitudinal fasciculus compared to the control group. MD values were significantly increased in the hippocampus, the anterior and posterior limbs of the internal capsules, the splenium of the corpus callosum, the right frontal lobe, and in the superior and the inferior longitudinal fasciculus. Microstructural changes of several corticocortical tracts associated with cognition were identified in patients with MCI. FA and MD values of DTI may be used as novel biomarkers for the evaluation of neurodegenerative disorders.

PURPOSE: To implant tissue chips in New Zealand rabbits, and thus redurce the frequency with which scattered VX2 carcinoma nodules and early metastasis develop in these animals. MATERIALS AND METHODS: VX2-carcinoma tissue chips of two different sizes were implanted under ultrasonographic guidance. In each of 12 New Zealand rabbits (group 1), there 1-mm tissue chips were implanted in the liver using an 18-gauge needle, and in the same way, one 3-mm chip with an added gelfoam pellet was implanted in the proximal lumen of the liver of each of ten other New Zealand rabbits (group 2). Three weeks after implantation, the animals underwent dvalphase CT scanning and were sacrificed, and the Number and size of tumor nodules, and metastasis were evaluated either macro-or microscopically. RESULTS: In ten rabbits in group I, a total of 21 nodules (16 in the liver, 5 in the peritoneal wall) were observed, which in nine rabbits in group 2, a total of ten nodules-all in the liver-were present. CT scans depicted tumor nodules in 50% of group-I rabbits, and in 29% those in group 2. Mean tumor diameter was 12 +/-9 mm in group 1 and 6.4 +/-3 mm in group 2. Histologic examination indicated the presence of nodular VX2 carcinoma, with varying degrees of central necrosis, a feature more prominent in group 2. CONCLUSION: To provide a well-localized tumor nodule in rabbit liver, tissue chip implantation of VX2 carcinoma, especially with added gelfoam, is a good alternative to intraparenchymal injection of tumor suspension.

PURPOSE: To determine the hepatic and vascular enhancement profiles with nonionic dimeric, iodixanol, contrast agent in the rabbit and to compare them with nonionic monomeric, ioversol, contrast agent. MATERIALS AND METHODS: Seven rabbits initially underwent hepatic dynamic CT scan with either iodixanol or ioversol, followed by repeated CT scan with other unused contrast agent with one week interval between scans. Pre and post contrast attenuation values of hepatic parenchyma, aorta and portal vein were measured sequentially. The mean enhancement of the hepatic parenchyma, aorta and portal vein were compared between two agents. The mean peak enhancement and peak enhancement time of the liver, aorta, and portal vein were also compared. RESULTS: The attenuation values of ioversol showed a greater mean hepatic enhancement than iodixanol from 18 seconds to 39 seconds after injection (from late arterial phase to early portal venous phase) with a statistical significance (p<0.05). The mean peak enhancement of hepatic parenchyma, aorta and portal vein was also greater using ioversol than iodixanol, but the mean peak enhancement times of ioversol and iodixanol were nearly identical. CONCLUSION: Ioversol may have the greater effects than iodixanol on hepatic tumor conspicuity, especially from late arterial phase to early portal veneous phase.
