Secondary malignant neoplasm of brain [C79.31], Reason for Study: ^Reason: eval for tumor resection History: left weakness Post right fronto-parietal craniotomy status.Previously seen right parietal lobe intra-axial enhancing masses (one at the right inferior parietal lobule and another at the precuneus) are not demonstrated on this scan with minimal tumor bed enhancement indicating near complete or complete resection status. Susceptibility lesions on tumor bed indicate operation related blood products. Minimal enhancement on the tumor bed may indicate postoperative changes, but may need follow up scan.The degree of brain edema and midline shift toward left do not show any significant interval change since prior scan.There is no evidence of acute ischemic or hemorrhagic lesion except resection bed blood products on this scan.The ventricles, sulci and cisterns are unremarkable and unchanged since prior scan. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Near total or complete resection status of the right parietal metastatic lesions, postoperative no unusual finding.2. Subtle enhancement of tumor beds are likely represent postoperative changes but needs follow up scan.3. Unchanged the degree of brain edema and midline shift toward left side since prior scan.
