Bell's palsy [351.0], Reason for Study: ^Reason: eval underlying structural lesions; neurosarcoidosis History: recurrent bell's palsy Bilateral facial nerves especially geniculate ganglions, tympanic segment and mastoid segment show enhancement on Gad infusion. Although the right side enhancement appears to be a bit more prominent than that of the left, the degree of enhancement should be interpreted as not significantly different.There is no evidence of acute ischemic or hemorrhagic lesion on this scan.There is no evidence of abnormal intra axial enhancement.There is no mass.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. 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.
Bilateral enhancement of facial nerves as described above, no definitive asymmetric or focal enhancement was seen.No evidence of acute ischemic or hemorrhagic lesion on this scan.No evidence of mass.
