Benign neoplasm of meninges, unspecified [D32.9], Reason for Study: ^Reason: resection of meningioma History: Meningioma Post left frontotemporal craniotomy status with extradural fluid collection underneath of the craniotomy site. There are diffuse dural enhancements, however, there is no evidence of residual meningioma on this scan.There is no evidence of acute ischemic lesion.Several susceptibility artifacts especially on the left side frontal and temporal lobe may indicate postoperative blood products.There are also blood products within the ventricular system especially bilateral lateral ventricle occipital horn.There is no evidence of abnormal enhancement.The ventricles, sulci and cisterns are symmetric and unremarkable. 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. Postoperative status of the left sphenoid wing meningioma.2. No evidence of residual mass on this scan.3. Some parenchymal and ventricular blood products with craniotomy site extradural fluid collections are procedure related, there is no post-operative unusual finding.
