Malignant neoplasm of brain, unspecified [C71.9], Reason for Study: ^Reason: astroblastoma resection/ seizures, yearly follow up, evaluate for changes History: yearly follow up for changes There is no evidence of acute ischemic or hemorrhagic lesion. Localized susceptibility lesion on the posterior aspect of resection cavity located on the left superior frontal gyrus is again seen, unchanged.There is no evidence of abnormal enhancement on the scan.High signal intensities on T2/FLAIR images surrounding resection cavity indicating postoperative changes, unchanged since prior scan.The ventricles, sulci and cisterns are unremarkable. There is no evidence of recurrent or residual mass, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and 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. Post resection status of left superior frontal gyrus lesion with postoperative changes, unchanged since prior scan.2. No evidence of recurrent or residual mass. No abnormal enhancement.3. No evidence of acute ischemic or hemorrhagic lesion.
