45 years, Female, trigeminal neuralgia, rule out brainstem lesion. Brain parenchyma appears within normal limits. Specifically no lesions within the brainstem are appreciated. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. No abnormal parenchymal or meningeal enhancement. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. There is moderate mucosal thickening involving the left sphenoid sinus. Bone marrow signal and extracranial soft tissues are within normal limits. Noted is an enhancing, likely small venous structure, coursing along the superior aspect of the cisternal segment of the right trigeminal nerve as well as along the medial aspect of the trigeminal nerve as it enters the Meckel's cave.
1. No brain parenchymal signal abnormalities or intracranial mass.2. There is an enhancing, likely small venous structure, coursing along the superior aspect of the cisternal segment of the right trigeminal nerve as well as along the medial aspect of the right trigeminal nerve as it enters the Meckel's cave. Finding is of uncertain significance and can be correlated with symptomatology (per EMR, patient's symptoms are left sided). Also note examination was performed per routine brain MRI protocol and additional high-resolution sequences of the trigeminal nerve including its extracranial course can be obtained if clinically warranted.
