Reason: evaluate for infarction or other abnormality History: loss of motor and sensory function of left lower extremity. Brain MRI appears within normal limits. No intracranial mass or abnormal parenchymal or meningeal enhancement to suggest metastatic disease. The ventricles and sulci are normal in size. There is no evidence of mass effect or herniation. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. The pituitary gland is normal in size. The paranasal sinuses and mastoid air cells are clear.
No evidence of intracranial metastatic disease. No evidence of acute infarct, hemorrhage, or mass effect.
