 There is evidence of interval development of the left fronto-parietal craniotomy for the biopsy of the left parietal intra axial lesion. There is extra dural fluid collections with blood products just underneath of the craniotomy site which is measured about 11.2mm.There is fluid fluid level within the lesion indicating local blood products within the resection cavity.There are irregular enhancement on the site of the lesion especially inferior and peripheral aspect of the original lesion which could represent residual tumor or could represent reactive changes after the surgery.There is no evidence of acute ischemic lesion on this scan.The ventricles, sulci and cisterns are symmetric and unremarkable. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Postoperative status of the left parietal intra-axial mass lesion as described above.In particular, intra lesional blood products, extra dural blood products and subtle enhancement especially on peripheral aspect of the lesion were demonstrated.
