Left trigeminal neuralgia. BRAIN MRI:Brain parenchyma appears within normal limits. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. Focal susceptibility along the left side of the posterior falx demonstrates no associated enhancement and compatible with a nonspecific dural calcification. T1-hyperintense, centrally T2-hyperintense material in the left lateral sphenoid sinus is compatible with a mucus retention cyst with inspissated secretions and was present previously on MRI/19/2009. This focus is medial to the foramen rotundum. There is trace mucosal thickening in the paranasal sinuses, elsewhere. There is asymmetric prominence of the right palatine tonsillar tissue, possibly related to left-sided tonsillectomy, but can be correlated with direct examination. There is also nonspecific prominence of the nasopharyngeal tonsillar tissue without suspicious masses.MRI OF THE CRANIAL NERVES:The cavernous sinuses and Meckel's caves are symmetric and preserved. There is no abnormal contrast enhancement along the trigeminal nerve cisternal segments or the other imaged cranial nerves. There is also no brainstem or root entry zoon lesion. No abnormal vasculature structure is appreciated at the origin of the left trigeminal nerve. There is no abnormal signal or contrast enhancement in the foramina rotunda and ovale. The orbital floors show no gross abnormality.
MRI of the brain appears within normal limits. Specifically no lesion to explain trigeminal neuralgia is appreciated. Please see additional findings above.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
