Benign neoplasm of cerebral meninges [D32.0], Reason for Study: ^Reason: Eval meningiomas. History: meningiomas. Multiple extra axial enhancing mass lesions are seen. Though the number of lesions appears to be unchanged, some of lesions especially one on the right frontal lobe in front of the pre-central gyrus (14.8mm x 15.4mm, was 13.7mm x 13.4mm) as well as a couple of falx lesions especially anterior aspect of the falx (11.4mm, was 11.1mm and 9mm was 7.6mm) demonstrate interval increase in size.Other lesions do not show any significant interval change in terms of size since prior scan.There is no evidence of acute ischemic or hemorrhagic lesion.Redemonstrated and unchanged right posterior temporal lobe susceptibility lesion since prior scan.About 4 mm sized enhancing lesion within the left internal auditory canal is again seen, unchanged in size and enhancement pattern.Right frontal parietal craniotomy with multifocal underlying foci of encephalomalacia indicating postoperative changes, unchanged since prior scan.The ventricles, sulci and cisterns are 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. Subtle interval increase of measured maximum diameter of extra axial enhancing lesions most likely meningiomas including right frontal precentral gyrus lesion and anterior aspect of falx lesions. Other lesions do not show any significant interval changes.2. No evidence of acute ischemic or hemorrhagic lesion.3. Right temporal susceptibility lesion as well as left internal with technical enhancing lesion do not show any significant interval change since prior scan.
