Clinical question: Rule out tumor or acute abnormalities. Signs and symptoms: Facial pain. Pre-and post-enhanced brain MRI:No diffusion weighted abnormalities.Examination demonstrate normal anatomical morphology and 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 on post enhanced series.Calvarium and orbits are unremarkable and without evidence of abnormal enhancement.Pre-and post enhanced IAC MRI:Bilateral internal auditory canals demonstrate normal symmetrical bilateral size and morphology and without detectable abnormal enhancement. The signal intensity and morphology of the visualized inner ear structures are unremarkable. There is no detectable signal abnormality or enhancement of the facial nerves.The signal intensity of bilateral mastoid air cells and middle ear cavities are beginning normal and without abnormal enhancement.The signal intensity and morphology of bilateral neurovascular bundles across the cerebellopontine angles and within the internal auditory canals is within normal and without abnormal enhancement. Pons and bilateral cerebellopontine angles demonstrate normal signal intensity and without abnormal enhancement. Bilateral Meckel's caves and trigeminal nerves demonstrate normal signal intensity and without abnormal enhancement.There is no detectable abnormal enhancement of the cranial nerves.
