 Postcontrast images are limited by patient motion. Incidental note is made of slight asymmetric prominence of the diploic veins along the right posterior parietal calvarium with no significant asymmetry in appearance of the convexity cortical veins. This is seen on 2801/8 and 3001/10, resulting in slight increased T2/FLAIR signal along this area of the calvarium. Correlating with the recent CT, there is evidence of osseous linear lucency correlating with a prominent diploic veins in this area. No abnormal arterial structures are visualized.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 parenchymal 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 right intracranial venous structures are prominent and therefore larger than the left. There is slight paucity of pituitary tissue within the sella. The remainder of the midline structures and craniocervical junction are within normal limits. There is trace fluid within the right mastoid air cells.MRA HEAD
1. No evidence of vascular malformation, although whole head MRA was not obtained inadvertently. No suspicious vasculature identified on slightly motion limited postcontrast imaging.2. Incidental prominence of diploic veins along the high right parietal calvarium as detailed above. Please correlate with area of concern, although this likely would not result in an audible finding. Consideration could be made for ultrasound interrogation of the temporal scalp.3. Motion limited MRA of the neck, demonstrating no significant abnormality. Unremarkable contrast-enhanced MRI of the brain and noncontrast MRA of the circle of Willis.4. Mild right mastoid fluid, for which clinical correlation is recommended.
