31 years, Female, Reason: Evaluate for ischemia vs. demyelinating disease History: L sided arm and leg weakness. Brain: Brain parenchyma appears within normal limits. 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. Postgadolinium images are motion degraded but demonstrate no abnormal parenchymal or meningeal enhancement. Major flow-voids are preserved.There is an expanded, partially empty sella. Minimal opacification of the left mastoid air cells. Paranasal sinuses are clear. Bone marrow signal and extracranial soft tissues are grossly unremarkable. Cervical Spine: Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate in height. There is straightening of the cervical spinal curvature which may positional. Alignment is otherwise maintained. Bone marrow signal is within normal limits. There is no appreciable cord signal abnormality within the limits of motion degradation on the axial images.Individual levels in the cervical spine as described below:C2-3: No significant compromise to the spinal canal or neural foramina.C3-4: No significant compromise to the spinal canal or neural foramina.C4-5: No significant compromise to the spinal canal or neural foramina.C5-6: No significant compromise to the spinal canal or neural foramina.C6-7: No significant compromise to the spinal canal or neural foramina.C7-T1: No significant compromise to the spinal canal or neural foramina.The vertebral artery flow voids appear to be intact. Paraspinous soft tissue structures appear within normal limits.
1. Brain parenchyma appears within normal limits. Specifically, no evidence of acute infarct or evidence of demyelinating disease.2. No signal abnormality involving the cervical cord is appreciated within the limits of motion degradation. There is also no significant spinal canal or neural foraminal stenosis at any level. 3. Partially empty sella which can be a normal variant or associated with intracranial hypertension in the appropriate clinical setting.
