Bell's palsy [G51.0], Reason for Study: ^Reason: Eval for neoplastic vs vasculitis History: Bilateral bells palsy in setting of SCLC. Brain MRINo evidence of acute ischemic or hemorrhagic lesion on the scan.There is no abnormal enhancement.About 2mm herniation of cerebellar tonsil through the foramen magnum, this is normal but can be said as benign tonsilar ectopia.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.MRI IACThe brainstem, cerebellum, vermis and tonsils are normal. The inner ear structures, cochlea, vestibule, semicircular labyrinth are normal. The internal auditory canals are normal with delineation of the facial, cochlear and vestibular nerves. No evidence of signal abnormality, mass or abnormal enhancement is noted.
