Male, 26 years old, with seizures, right lower extremity weakness, and brain lesions status post biopsy. An irregularly marginated, enhancing lesion is redemonstrated centered on the left cingulate gyrus. The lesion is predominately solidly enhancing with a somewhat feathery appearance along its inferior margin which encroaches into the corpus callosum. The lesion is similar in size when compared to the immediate prior Stealth MRI, but has increased relative to the examination of 05/26/16. Associated surrounding edema has also increased.A smaller but similar-appearing, solidly enhancing lesion is again seen within the left parietal lobe. This lesion is also unchanged relative to the immediate prior examination, but increased in size when compared to the older study. Adjacent postbiopsy changes are seen including a burr hole in the left parietal bone and a small biopsy cavity immediately anterior to the enhancing lesion.No other pathologic intracranial enhancement is observed. However, there are scattered small foci of white matter T2 hyperintensity within the right cerebral hemisphere which are not significantly changed. No areas of significant intracranial hemorrhage or any abnormal extra-axial fluid are seen.
1.Findings are seen compatible with left parietal lobe biopsy. A biopsy cavity is evident just anterior to the enhancing nodule within the left parietal lobe.2.Solidly enhancing lesions within the left parietal lobe and in the left cingulate gyrus are redemonstrated. When compared to the immediate prior Stealth MRI, these lesions and their associated edema have not changed, but when compared to the older MRI, they have increased in size.
