 Images are moderately limited by patient motion, especially postcontrast imaging. Postoperative changes are again seen from a previous right frontal approach biopsy of the thalamus, with a few foci of susceptibility. There is redemonstration of mild subtle residual gyral thickening along the right insula, similar to prior exams. There is no corresponding enhancement.The ventricles and sulci are within normal limits. The cisterns remain patent. There is no midline shift or mass effect. There are no new 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.
Continued stable appearance of mild residual asymmetric gyral thickening along the right insula, within motion limitation.
