Clinical question: Metastatic breast cancer, baseline study prior to starting on clinical trial. Signs and symptoms: Research required, no symptoms. Pre and post enhanced brain MRI:No diffusion-weighted abnormalities.Examination demonstrates normal anatomical development of brain with normal signal intensity on all MRI sequences.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and brain myelination.There is no detectable abnormal parenchymal or left meningeal enhancement to suggest metastatic disease.Calvarium and orbits are unremarkable and without evidence of metastatic lesions.All visualized paranasal sinuses and bilateral mastoid air cells and middle ear cavities demonstrate normal pneumatization signal patterns.Intracranial venous sinuses demonstrate normal signal intensity and normal pattern of enhancement.
Unremarkable pre and post enhanced brain MRI.
