 There are stable postoperative changes from prior resection of the right temporal lobe with encephalomalacia. There is slight asymmetry in the size of the ventricles with the right ventricle slightly larger than the left, as well as mild ex vacuo midline shift to the right, stable since the previous MRI dated 2/29/2008.There is a cranioplasty plate that severely distorts the diffusion images. However, in the visualized field of the diffusion images, there are no abnormalities. There are punctate susceptibility foci in the right middle cranial fossa that likely represent chronic blood products from previous surgery.There is a punctate enhancement in the pons with questionable curvilinear enhancement anteriorly that may represent a tiny capillary telangiectasia and possible adjacent developmental venous anomaly.There is a chronic fluid in the right mastoid.
1. Stable MRI of the brain. Encephalomalacia seen in the right temporal lobe, unchanged. No abnormal enhancement.2. Stable chronic opacification of the right mastoid.
