Male, 10 years old. History of a left parietal DNET, S/P craniotomy tumor resection, 6 month f/u since last MRI, evaluate for residual tumor or new tumor. Again seen are postoperative findings of left parietal craniotomy for resection of a small left parietal tumor. The resection cavity lies along the posterior aspects of the supramarginal and angular gyri in the inferior parietal lobule. There is stable to slightly decreased overlying dural enhancement. A small area of curvilinear enhancement extending into the resection cavity from the dura is unchanged and likely postoperative in nature. There is no evidence of residual or recurrent tumor.The pineal gland is prominent and enhancing, unchanged from prior studies. Otherwise, the brain morphology and signal characteristics are within normal limits. There is no evidence of intracranial hemorrhage, mass effect or edema. The ventricles and basal cisterns are normal in size and configuration. The midline structures and craniocervical junction are within normal limits. Normal flow-voids are demonstrated in the major intracranial vascular structures.The paranasal sinuses are clear. The visualized mastoid air cells are clear. The orbits are unremarkable.
1. Continued evolution of postoperative findings related to resection of a small left inferior parietal lobule tumor, without evidence of residual or recurrent tumor.2. Enhancing pineal mass is unchanged from prior exams.
