Secondary malignant neoplasm of brain [C79.31], Reason for Study: ^Reason: eval postop changes History: s/p crani for tumor There is evidence of right frontal craniotomy with near total resection of the right frontal lobe mass with minimal surrounding enhancement which could represent postoperative changes including resection site blood products.There still has remained mass effect of the resection site with minimal midline shift toward left side, no significant change since prior scan.The craniotomy site shows subgaleal and extra axial fluid collections which are likely to be procedure related.There is no other abnormal enhancement seen.The ventricles, sulci and cisterns are grossly symmetric and unremarkable. There is no restricted diffusion/acute ischemia, or new hemorrhagic lesion. The cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Right frontal craniotomy postoperative changes including subgaleal and extra dural fluid collections.2. Near total excision of the right frontal mass lesion with minimal resection site enhancement.3. No acute ischemic lesion. No hemorrhagic lesion except resection site blood products.
