Clinical question: History of melanoma with complaints of headaches. Signs and symptoms: As above. Pre-and post's brain MRI:Negative diffusion weighted series.There is normal anatomical morphology as well as 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.Calvarium and soft tissues of the scalp demonstrate normal signal intensity and without abnormal enhancement.Minimal bilateral (right greater than left) anterior ethmoid air cell opacification is noted and unremarkable paranasal sinuses otherwise.Bilateral mastoid air cells and middle ear cavities demonstrate normal pneumatization signal pattern.
Negative pre-and post enhanced brain MRI.
