Altered mental status [780.97], Reason for Study: ^Reason: CVA? History: altered mental status Due to patient incorporation, the exam was prematurely ended. As a consequence, there is no acquisition of gradient echo sequences.There is a focal high signal intensity on diffusion weighted image (series #406, image 200/32), with restricted diffusion on the right precentral gyrus.There is a focal encephalomalacia seen on the left side of upper pons most likely representing previous stroke.Underlying brain shows patch confluent high signal intensity on periventricular white matter on FLAIR images indicate nonspecific small vessel ischemic disease.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses are clear.Bilateral mastoid air cell show fluid collection.Nonvisualization of right eyeball lens.
1.Focal acute ischemic infarction, right precentral gyrus as described above.2. Chronic infarction with encephalomalacia seen on the right upper pons with nonspecific small vessel ischemic disease.3. Hemorrhagic lesions cannot be precisely evaluated due to Mr. Gradient-echo sequences, however, there is no other evidence suggesting intracranial acute hemorrhagic lesion on the scan.
