 The ventricles and sulci are within normal limits. The basal cisterns remain patent. There is no midline shift or mass effect. There are no areas of abnormal signal or pathological enhancement. There is no diffusion abnormality. No extra-axial fluid collection is identified. Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. There is redemonstration of a chronic right orbital floor blowout fracture with caudal extension of orbital fat. There is also associated deformity with rounding of the right inferior rectus muscle. There is minimal adjacent patchy opacity within the right maxillary sinus.MRA HEAD
1.No MR evidence of demyelinating disease within the brain or cervical spine.2.Unremarkable MRA of the head and neck, although with limited evaluation of the V2 segments secondary to venous contamination. Grossly, cervical vertebral artery flow voids are present on MRI of the cervical spine.3.Minimal lower cervical spondylotic changes without significant stenosis at any level.4.Redemonstration of chronic right orbital floor blowout fracture.
