Other speech disturbances [R47.89], Reason for Study: ^Reason: any ischemic lesions? History: transient speech arrest No evidence of acute ischemic or hemorrhagic lesion on this scan.There are enlarged CSF spaces especially in front of bilateral cerebellar hemispheres without showing any evidence of cerebellar dysplasia, atrophy or other structural change. Thus, most likely explanation may include extra axial CSF collections such as arachnoid cyst. Multifocal lacunar infarctionUnderlying brain show multifocal patchy scattered high signal intensity lesions on bilateral periventricular white matter and centrum semiovale indicating non specific small vessel ischemic disease.The ventricles, sulci 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 and mastoid air cells are clear.
1. Extra axial CSF collections especially in front of bilateral cerebellar hemispheres suggest possible arachnoid cysts.2. Non specific small vessel ischemic disease.3. No acute ischemic or hemorrhagic lesion.
