Other malignant neoplasm without specification of site. The CSF spaces are appropriate for the patient's stated age with no midline shift. There is redemonstration of a small left occipital lobe lesion which enhances following contrast administration and is surrounded by hyperintense signal on FLAIR and T2 images. It currently measures 5 mm diameter and previously measured 5 mm diameter.There is a mild degree of periventricular and subcortical confluent hyperintense white matter lesions present identified on the FLAIR and T2 images. These were also present on the prior exam and have not substantially changed.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate some mucosal thickening in the left sphenoid sinus. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.A left occipital lobe lesion is stable on the current exam when compared to the prior exam.. 2.Periventricular white matter lesions are present of the moderate degree which are stable since the prior exam. These are nonspecific. They could be vascular related or related to prior treatment.
