 Brain: There are no T2/FLAIR abnormalities. There is no abnormal signal in T1. There are no restriction or susceptibility abnormalities. Ventricular size is normal. There is no midline shift. There is no evidence of hemorrhage or mass effect. No structural abnormalities. The vascular flow voids are normal. Cervical spine: There is normal alignment or the vertebral bodies. There is no subluxation. There is no definite ligamentous STIR hyperintensity. The intervertebral disc spaces are preserved. No evidence of cord abnormal signal. The neural foramina are within normal limits. MRA neck: Dissection protocol was inadvertently not obtained. The right vertebral artery along the V2 segment is not well visualized due to venous contamination. Axial reformatted images suggest that the vessel is irregular and discontinuously narrowed, although the T2 flow void appears more uniform on MRI of the cervical spine. The axial T1-weighted images do not demonstrate any gross evidence of mural hematoma along the vertebral arteries. The dominant left vertebral body is within the normal limits. The common carotid arteries and the cervical carotid arteries are within normal limits.
1. Unremarkable MRI of the brain and of the cervical spine.2. The V2 segment of the right vertebral artery is questionably narrowed and irregular, although evaluation is limited due to venous contamination. Arterial dissection cannot be entirely excluded. If there is clinical suspicion for dissection, CTA of the neck may be obtained. Please note that dissection-specific sequences were inadvertently not obtained.Dr. Jason Choi was notified by Dr. Arie Franco on 11/8/2015 at 1:40 PM
