Clinical question: Stage IIIc melanoma restaging. Signs and symptoms: Melanoma. Pre and post enhanced brain MRI:Negative diffusion weighted series.Examination demonstrates normal anatomic cord morphology and normal signal intensity of brain parenchyma on all MRI sequences.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and brain myelination.There is no detectable abnormal parenchymal or leptomeningeal enhancement to suggest metastatic disease.Normal signal intensity of the calvarium and unremarkable images through the orbits and without detectable abnormal enhancement.On paranasal sinuses and bilateral mastoid air cells and middle ear cavities demonstrate normal pneumatization signal pattern.
Negative pre and post enhanced brain MRI.
