Clinical question: Adenocarcinoma, initial staging. Signs and symptoms: Adenocarcinoma. Pre-and post-enhanced brain MRI:Negative diffusion weighted series.The anatomical morphology as well as the signal intensity of brain parenchyma remains within normal on all MRI sequences.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and brain myelination.There is no detectable abnormal enhancement the brain parenchyma or the meninges to suggest metastatic disease.The signal void of major intracranial arterial branches are identified.The signal intensity of the intracranial venous sinuses and pattern of enhancement is within normal limits.Calvarium demonstrate normal signal intensity and without detectable abnormal enhancement.Unremarkable images through the orbits and including axial fat sat post enhanced series.All paranasal sinuses and bilateral mastoid air cells and middle ear cavities demonstrate normal pneumatization signal patterns.
Negative pre-and post enhanced brain MRI.
