Disorder of brain, unspecified [G93.9] / Secondary malignant neoplasm of brain [C79.31], Reason for Study: ^Reason: s/p crani for tumor History: speech changes Limited exam due to patient's motion, gradient-echo scans was not obtained and post enhancement scan was also not obtained.Previously seen left parietal opercular mass is again seen with the significant surrounding edema. The extent of mass effect appears to be slightly increased results midline shift toward right side at the level of foramen of Monro, on axial scan, the degree of midline shift is measured about 7 mm.The size of mass itself has been decreased (22.7mm x 24.4mm x 25.6mm) with the increased component of low signal intensity especially posterior inferior aspect of the mass lesion indicating intralesional blood products.There is also about 9 mm thickness extra axial, intracranial blood products on the operation site.No change of right parieto-occipital lesion with the prior hemorrhageNormal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Interval partial resection status of the left parietal opercular mass.2. Intra-lesional blood products with postoperative increased surrounding edema and mass effects since prior scan.3. Extra axial, intracranial fluid collection likely represent blood products overlying the operation site as described above.
