Brief Summary
Combidex (ferumoxtran-10) is an ultra-small iron oxide particle covered with a sugar coating. It has been evaluated as an MRI contrast agent for use in imaging well perfused organs such as the liver and spleen and for imaging lymph nodes. In this study, Combidex is being used to compare the standard imaging agent, Gadolinium, in imaging brain tumors and the area adjacent to the tumor location. Combidex may provide the ability to better see brain tumors and inflammatory lesions on magnetic resonance imaging (MRI) scans. Combidex may be useful in its ability to cross blood vessels into brain tumors, and because of its size and ability to get into the area next to brain tumors, could assist in the treatment of brain tumors with other drugs in the future.

Outcome Measures
Primary Outcomes (1)
Number of Participants Who Experience Optimal Imaging in Adult and Pediatric Brain Tumors to Establish Timing and Sequencing Parameters of Combidex.
Signal intensity change in participants with Pre and 24 hours Post Combidex on T1, T2, T2\* MRI sequences will be assessed (some patients undergo scans at 3 and 72 hours in order to assess radiographic changes at these time points). Combidex will be administered in dose 2.6 mg/kg in adults with high and low grade gliomas, metastases, meningiomas, and PNET; and in pediatric patients with astrocytomas grade i-iv, brain stem gliomas, ependymomas, CNS germ cell tumors, and PNET.
24 hours (some patients between 3 and 72 hours) after administration of Combidex
Secondary Outcomes (3)
Assess the Cellular Uptake of Particles in Brain Tumor Patients by Comparing Imaging Results With Histology and Electron Microscopic Examination of Biopsy Tissue
2 years
Compare Combidex Imaging in Brain Tumor Patients, With Other CNS Inflammatory Lesions Such as Multiple Sclerosis and Stroke.
2 years
Compare Pre- and Post-op Gd Enhanced MRI Combidex Enhanced MR Imaging Done Pre-, Intra- and Post-operatively, to Assess the Degree of Resection and Residual Tumor.

ACTIVE COMPARATORAdults with Inflammatory lesions (stroke or MS) to receive Combidex only
Interventions
neuro-surgical tumor biopsy or resection to assess particle localization. Biopsy (stereotactic, when possible) will take place following the 24 hour post- Combidex MR and within 48 hrs of i.v. Combidex administration. Biopsies will be taken from the tumor, brain around tumor (BAT) and brain distant to tumor and the MR localization and histology will be compared. The tissue will be obtained by either resection or needle frameless stereotactic biopsy.
