Acute mobile thrombus of the abdominal aorta after chemotherapy is a very unusual finding, which can be a potential source of arterial embolism. We report here on a case of an acute mobile aortic thrombus with renal infarction. We successfully treated the patient with hybrid operation-open surgical and endovascular approach. Our case shows that hybrid treatment using wire-directed balloon catheter thrombectomy is a feasible, minimally-invasive treatment for a mobile aortic thrombus.

Endovascular repair of abdominal aortic aneurysm is associated with low morbidity and mortality rates when compared to open surgery, and this can be used in patients who are at a high risk for open surgical repair. Also, secondary intervention is an important for achieving intermediate and long term success of endovascular repair of abdominal aortic aneurysm as this can resolve complications. We report here on endovascular stent-graft placement and a secondary interventional procedure in the abdominal aortic aneurysm of a patient who had a previously inserted iliac stent.

A patient is described who was presented with a little finger tip sized palpable nodular mass on left calf muscle for 2 years of duration. The pathologic result of the biopsy specimen for nodular mass showed a clear cell carcinoma. The full metastatic work up demonstrated tumor in the right kidney, with no other detectable primary focus. Result of the radical nephrectomy exhibited renal cell carcinoma confined within renal parenchyme. The patient was treated with IFN-alpha-2b as adjuvant therapy and now is on close observation without the evidence of tumor recurrence.

It is well recognized that diabetic patients have small pupil. The most likely cause of the abnormally small pupil in diabetics is decreased funcitor of the autonomic nerves. We measured pupil size in 141 control subjects and 53 diabetic patients (29 cases with symptomatic autonomic neuropathy, 24 cases without symptomatic autonomic neuropathy) with portable pupillometry, PUPILSCAN in darkness. Pupils become smaller in healthy and diabetic subjects with advancing age.

PURPOSE: To determine the influence of manganese dipyridoxyl diphosphate (Mn-DPDP) on MRI and proton MRS. MATERIALS AND METHODS: In an in-vitro study designed to determine changes in the lipid peak at 1.3 ppm, 4.7T MR equipment was used to obtain proton MR spectrographic images of a lipid solution of varying concentration, with and without Mn-DPDP. Before; at 10, 20, and 30 minutes; and at 1, 2, 4, and 24 hours after the IV injection of Mn-DPDP (10umol, 1ml/kg), the concentration of Mn in liver tissue was measured by atomic absorption spectrometry. At the same intervals, T1-weighted MR images were obtained, the signal intensity ofthe liver was thus determined, and the relative enhancement ratio was calculated. MRS of rabbit liver was performed serially at the same intervals, and the peak areas of metabolites, as well as their peak areas relative to lipids, were calculated. The findings were correlated with tissue Mn concentration. RESULTS: At 1.3 ppm with Mn-DPDP, MRS showed that the peak area of the lipid had decreased. Tissue Mn concentration increased just after Mn-DPDP injection and peaked after 20 minutes, decreasing to a level within the normal range after 24 hours. Serial changes in the signal intensity of the liver, as seen at MRI, showed a similar pattern to that of Mn concentration. There was reverse correlation between serial change in the peak area of lipids at 1.3 ppm and Mn concentration after Mn-DPDP injection. CONCLUSION: At T1-weighted MR imaging, the injection of Mn-DPDP led to the enhancement of liver tissue, and at MRS, the lipid peak at 1.3 ppm decreased. There was close correlation between these effects and tissue Mn concentration.

PURPOSE: To investigate the in vivo proton MRS features of various focal hepatic lesions and to distinguish these features according to the involved. MATERIALS AND METHODS: Twenty-five hepatic lesions [hepatocellular carcinoma (n=7), cholangiocarcinoma(n=3), metastatic tumor (n=9), hemangioma (n=3), hepatic abscess (n=2), lymphoma (n=1)] underwent proton MR spectroscopy using a 1.5T unit and a localized proton STEAM sequence, without respiratory interruption, The findings of this in-vivo sequence were then reviewed, with particular attention to the presence and location of dominant peaks. RESULTS: In-vivo proton MR spectra were successfully acquired in all cases. A dominant lipid peak appeared in the MR spectra of the hepatocellular carcinomas, metastatic tumors, hepatic abscesses, lymphoma, one hemangioma and one cholangiocarcinoma(88%) at 1.3ppm, but not in two cholangiocarcinomas and one hemangioma. The spectral peaks of other metabolites appeared very irregular and even different in the same disease. CONCLUSION: In focal hepatic lesions, the spectra obtained during in-vivo proton MRS were useful, and a lipid peak was most frequent and dominant. Among the various neoplasms there were, however, no specific MR spectral features, and nor did such features vary according to the specific pathologic entity.
