Subcutaneous fluid collection: An imaging marker for treatment response of infectious thoracolumbar spondylodiscitis.

Purpose: To evaluate prevalence of subcutaneous fluid collection (SFC) in infectious thoracolumbar spondylodiscitis (SD) compared with control patients and to investigate correlation between volume changes of SFC and treatment response of SD.

Materials And Methods: This retrospective study was approved by our institutional review board. From April 2011 to March 2012, 49 patients (24 SD and 25 non-SD patients) were enrolled.

Comparative study of vascular enhancement on post-contrast CT using three dosages of iodinated contrast media for the aim of detecting brain metastasis in patients with lung cancer.

Objective: A prospective double-blind randomized study was performed to compare the contrast of vascular enhancement using three dosages of iodinated contrast media for a possible metastatic lesion in the brain.

Materials And Methods: Sixty-six patients with lung cancer received brain computed tomography (CT) with intravenous administration of iodinated contrast medium (CM). The patients were randomly assigned to receive one of the three types of CM: 30 g iodine, 24 g iodine, and 15 g iodine.

Trans-arterial infusion chemotherapy for recurrence of pleural dissemination after thymectomy.

We present a report of trans-arterial infusion chemotherapy through the intercostal arteries and subphrenic artery for pleural dissemination of recurrent thymoma after thymectomy. The disseminated tumor did not enlarge for more than a year after this treatment, and there were no side effects. Trans-arterial infusion chemotherapy appears to be a preferable procedure for pleural dissemination of thymoma.
