History of atypical meningioma prior resection and radiation therapy. Follow-up examination. The MRI exam was a scheduled to have pre and post gadolinium enhancement. However, due to patient's left-sided severe pain, the patient wanted to abort the exam prior to gadolinium enhancement. There is no evidence of acute ischemic lesion on the scan.Again there is evidence of tissue loss on right frontal lobe and left frontal lobe with frontal craniotomy and overlying extra axial fluid collections. Encephalomalacia on bifrontal lobes are also shown.Above findings do not show any significant interval change since April 17, 2014.There is no evidence of postoperative unusual signal intensity on the scan. There is no evidence of recurrence of the tumor on this limited scan.The ventricles, sulci and cisterns are symmetric and unremarkable. No change since prior scan. There is no mass, mass effect, edema, midline shift, or restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear. Retention cyst on the left maxillary sinus.
No evidence of acute ischemic lesion.Post surgical resection status of bi-frontal atypical meningioma, no interval change since prior study and no evidence of recurrence on this limited scan.Postgadolinium enhancement study was not performed due to patient pain.
